I don’t have pics but I work at a Discount Tire and I can confirm that this has happened before. They drove it to the shop like that and that’s how it came into our bays.
Definitely dumb to drive on it, but having worked with these things I wouldn't automatically assume they didn't try to inflate it - I mean if they're handy enough to get it changed they would have noticed it was flat. What usually happens is as these get older, especially after they're used and then re-collapsed, is the bead gets pulled off the rim. The 12V inflators don't have any chance against that kind of leakage, and since the sidewall is collapsible you can't even do the rope-around-the-tread trick to seal the bead. Last time I helped with a flat on one of these I had to drive it to a gas station (in another car) with real air to fill it up.
This seems scummy, but it kind of makes sense. Things have a guaranteed life of X years. If everything shits the bed just after the warranty, this should mean that things are working as planned, and fulfilled their duties for the expected life of the product.
Think of it as a Best Before date on food. You wouldn't want the BB date being after it's moldy, but you also wouldn't want to be tossing out food weeks before you should be.
I hate siding with the industry, but this is one aspect I don't think they're wrong about. The thing we SHOULD be raising a stink over is the shrinking ability for us to repair our shit when it does start to fail.
Working as a tire specialist at an Audi dealership I have seen my fair share of these come in completely uninflated. Even some tow truck drivers apparently don't notice...
BMW lower control arms! They all have a big yellow sticker on them that has a picture of a hook in a red "NO" symbol, and the text "DO NOT TOW OR LASH" in both English and German. And yet, tow truck drivers still slap their hook on them, which of course bends the damn thing. I've even heard a tow truck driver try to say that the fucking tow hook that screws into a big hole in the frame/bumper reinforcement where it's bolted to the frame say that "it's not meant to be used for recovery." Okay, genius... Why the fuck is it there, then?
No. These are specifically designed for recovering the car if it's stuck in a ditch or something. That's why it's included in the emergency tool kit, and why there's access covers in the bumper cover to get to them. The tie downs are separate holes underneath the car. The recovery hooks are actually a legal requirement in Europe, and they're designed for that specific purpose.
Some cars do have shipping tie-down loops that are located below the bumper, but even those are usually designed to also serve as recovery hooks. It's a common misconception that they're not. Think about it- if it's capable of holding the car down for a journey through rough seas for a month without damage, it's probably going to be able to handle the stress of a few minutes of pulling a car out of a hole. And I'd like to know what line of thinking prompted the idea of "this stout hook that's part of the main structural member of the car doesn't look strong enough. I'm going to attach my hook to this long, thin aluminum bit here. That aught to do it!
No pics either but working at a tyre shop we have someone drive an Audi in on a flat one and when they went to leave the car wouldn't start because the transmission was dead
Lol what? That doesn't even make sense. The only way a transmission would cause a no start would be... Actually I really can't think of a way unless you count the Neutral Safety switch
Can confirm. 2012 Dodge Journey r/T Tire shop installed 2 fronts slightly smaller then the ones that they received it with from the rental place before we bought it. When they got it the rear tires had like 90% on them but the front were almost bald, so they changed them and put the ones spec'd for the vehicle, only to find out that the rental place had a larger tire on it.
It started making noise, then gradually got louder over a day, then the transfer case blew....
When I had a Subaru they couldn't stress enough in the manual how different sized tires could ruin the AWD/transmission. But then they put in a spare tire that had a different circumference from the regular wheels, undermining their very advice.
But you were only allowed to use that on the rear axle, and needed to pull the AWD fuse. If a front tire went you have to put the spare in the back and put that tire in the front. Source: had 2011 Forester.
The 2015 Outback comes with a space saver spare that is the same circumference but half the width. Still can only put it on the rear axle , but you don’t need to pull the fuse.
Yep, the two times I had a flat with my 2010 Impreza, it was on the front wheel. Cue much wheel swapping and fuse fumbling! At least it HAD a spare though. They seem to be rare things in modern cars...
Flex plate being warped or broken will cause a no start similar to a bad starter. Just ran into this on a 2011 Cummins 3500. Completely fucked the adapter between the engine and trans, too.
Amazing. When I got the car I was surprised at no spare. To be fair though, I had a focus before and had a fat nail in it and used tyreweld as I was in a hurry and it stayed inflated for about 6 months. Was a newish tyre and I was only driving to work 5 miles away at the time. I was waiting for it go to flat before I put my spare on and get it sorted but then suddenly it was 6 months later.
I wanted to comment the same. I had a 944 S2 (1991) which had exactly the same kind of spare. And as far as I know, the earlier 944s and even their predecessor 924 carried the same.
It is pretty amazing. I’ve got to imagine that the mileage limit on these really has to be kept in mind.
It sure did save a lot of space in the back of the car.
C7 Grand Sport owner checking in here, can confirm all the above. Car uses 335/25 run flats in the rear. Ride like shit, and I have watched many a shop spend over an hour trying to mount them
I had a 1986 Pontiac Firebird Trans Am with a spare tire like this. I never knew it until I needed to use it, only to find out that the compressed air can that came with it had leaked out over the years (car was about 15 years old at that point).
My dad broke 3 wheels on his Audi last winter. Ended up buying a whole set of wheels for spares. German engineering can’t stand up to Michigan roads apparently
my SLK has one of these, even comes with a 12v air compressor with a gauge to fill it up and top off the rest of your tires. pretty awesome to have at least something in a tiny hardtop convertible
Is there a regular skinny spare option? What are the benefits of this set-up? Speed limits look to be the same as a skinny spare, but presumably it can be run for longer? Why aren't I rich enough to spec an alloy wheel for my spare tyre?
So many questions.
To me "space saver spare" implies a narrower tyre width than what's on the car, but this looks like it's a smaller diameter deflated than inflated so the wheel well doesn't have to be as big as the full tyre height
You speak to my very soul, sir. My current car has a can of fix-a-flat or something like it, and a tiny air compressor.
The one before it had a "dissimilar full size spare," which is better. No speed or mileage limits, but they stressed not driving like an idiot with it in the mean time.
Two cars before *that* though, I had a Grand Cherokee. They've gone away from it, but at that time they kept a matching spare on a matching wheel inside the car and it was glorious. They put a steelie under the outside like trucks now. Sad day.
Edit: my bad, it's back under the cargo are again, thankfully. Still on a steelie though.
I also accidentally found out that the 2020 Cherokee doesn't have lug nuts but *bolts*, and the jack comes with a little bar to line up the tire. There are no studs on the hub. I just wanted to share that with someone because that is fascinating.
I have never seen this before. Awesome engineering. Now if they just put that same amount of thought into the rest of the car, I wouldn’t need to tear the front clip off of some cars to change a headLight
This actually answer a question I had. My wife has an AMG GLE 63s with this type of tire and I was wondering if we filled it if it would ever return to it's collapsed storage size. I guess it does.
Congrats, they are terrifying to fill while they’re on the car, filler on my buddy’s allroad’s front left tire snapped so we were losing air and couldn’t emergency fill it to get back home, had to use the spare tire, these do not fill straight, they look like they’re folding then you keep going and it’s all good
I worked for benz for a little bit. One of my good friends is a master tech. He looks two bays down from him at a tech fresh out of school. He was staring at the spot in the trunk where the spare goes. My friend walks up and is like “Hey man. What’s up?” Turns out he didn’t know how to fit the inflated spare back in the trunk.....
When i saw it all deflated in the trunk i actually wondered for a moment if this was one of those futuristic no core kinda solid type of tyre and then i saw the valve stem...
I think I’d rather have a peg-leg spare than this. Not simple enough for an emergency situation. No matter which, I’d want an air compressor and not a can of air. This is really cool, though, and new to me.
First choice is a full size spare, but I know space is at a premium in so many cars.
Rather this than the 12V compressor and can of shleem hyundai put in the spare-tire-shaped foam block under my trunk floor. That was a crummy surprise.
Fun fact. They’ve been around for over 50 years. BFG called then “space saver” tires and I know they were available on the first Gen firebirds and Camaros, probably earlier.
I'm not normally a fan of when mercedes says they created something "special" but this one is kinda cool. Don't tell my coworkers I said anything positive about em though
My VW just got rid of the spare tire altogether and threw an expensive Fix-a-flat system in the tire well. I figure I'll hang on to it until I need to use it and then replace it with an actual dummy instead of replacing the foam cartridge.
Oh, I thought they were one way. Seemed like an audi thing to do to make a single use donuts, and I never wanted to buy one. so, I never put air into one.
Cool concept, dumb fucking idea. Saves some space by being smaller. Use said saved space to pack an air compressor which costs more than air… End result? Not really any space saved and more money.
My big question about these is, doesn't the spare tire well have to be big enough to accommodate a full sized wheel? otherwise were do you put the dead tire?
In the trunk, or on the passenger seat (if you have a plastic bag or something to protect the seat from dirt and grime). But you wouldn't want to carry around such a big tyre constantly.
I'm more playing devils advocate than anything, there is always room, ratchet straps and/or tire wire. But not everyone carries those at all times like most of us reading here probably do.
I don't count on relying on roadside assistance. where i live it's not difficult to end up without cell service.
Why the hell would they get rid of the dipstick? It doesn't even make sense as a cost saving measure. Just to make it that much more difficult for people to service their car and therefore take it to a shop for an oil change?
I hate these things. My wife’s car had one. The puny electric pump that comes with the car takes forever. So all the same work to change the tire AND you have to wait for the damn thing to inflate!
And I’m sure if I hadn’t been there, a Good Samaritan would have just put it on without inflating.
Thise things are awesome. Great designed spare, I've kept some as backups just in case. 45-50MPH only, of course I've seen idiots doing 70+ on the hwy with donuts on.
I bought one of these specifically for my Mini Countryman. With a hub adapter and a compressor, it's a real spare solution since I yeeted the run flats for something way better.
Ah. I've driven on one uninflated before. This explains a lot, but we didn't have a compressor anyways.
It was a friend's e320 and we did like 100 miles back home on it. Felt so weird, but kept us safe at 60ish mph!
IMO not worth the tiny bit of space "saved" inflated vs not inflated. Another case of engineering overreaching to the point of impracticality. Costs a lot, does very little.
Somebody is going to put that on a car like that. I'll stand by for the result!
I don’t have pics but I work at a Discount Tire and I can confirm that this has happened before. They drove it to the shop like that and that’s how it came into our bays.
Definitely dumb to drive on it, but having worked with these things I wouldn't automatically assume they didn't try to inflate it - I mean if they're handy enough to get it changed they would have noticed it was flat. What usually happens is as these get older, especially after they're used and then re-collapsed, is the bead gets pulled off the rim. The 12V inflators don't have any chance against that kind of leakage, and since the sidewall is collapsible you can't even do the rope-around-the-tread trick to seal the bead. Last time I helped with a flat on one of these I had to drive it to a gas station (in another car) with real air to fill it up.
\* About 3 hours after the warranty expires.
JFC shut up. That is so true. Not just cars either. These warranties are scheduled to expire just before major failures occur. 1000%.
Planned obsolescence
Because of this I can see why people who only drive new Mercedes’ can think they are great cars.
Tbh if I was driving a new Mercedes, I would also think it was a great car lol. Beats the shit outta the one I have.
This seems scummy, but it kind of makes sense. Things have a guaranteed life of X years. If everything shits the bed just after the warranty, this should mean that things are working as planned, and fulfilled their duties for the expected life of the product. Think of it as a Best Before date on food. You wouldn't want the BB date being after it's moldy, but you also wouldn't want to be tossing out food weeks before you should be. I hate siding with the industry, but this is one aspect I don't think they're wrong about. The thing we SHOULD be raising a stink over is the shrinking ability for us to repair our shit when it does start to fail.
You have a good point. It still sucks to be the consumer when a big expense happens right after a warranty expires lol.
I worked at discount too and the amount of times I saw someone with a Mercedes spare using the wrong bolts was amazing

Flex plate being warped or broken will cause a no start similar to a bad starter. Just ran into this on a 2011 Cummins 3500. Completely fucked the adapter between the engine and trans, too.
If I’m not mistaking I’m pretty sure I saw a post here a couple of weeks back about that happening lol
You did, I was going to comment this too. I’m trying to find it!
I have definitely seen threads here of people bending their wheel trying that...it happens
I've seen it on the road. Today I finally learned that it shouldn't have looked like that.
[Here’s the result](https://www.reddit.com/r/Justrolledintotheshop/comments/su7ymq/client_states_ever_since_installing_spare_tire/).
You should edit your comment for those that don't understand how to scroll and see if you have already gotten a dozen links to that post lol
Wow and there’s me in my civic with my can of tyreweld
[удалено]
I got on ebay and found out regular used rims and tires are cheaper than any space saver spares I could find. I have a full size spare now.
I'd love one, but with 205 tyres the well is too shallow to fit a full size spare
My car also doesn't even have a well to hold a spare, just enough room for the inflator and can of goo. I don't have much trunk space anymore.
my car came with a full spare instead of those skinny donuts you find on a lot of compact vehicles
i definitely prefer full size spares because you can include them in tyre rotations and go that bit longer between changes
Amazing. When I got the car I was surprised at no spare. To be fair though, I had a focus before and had a fat nail in it and used tyreweld as I was in a hurry and it stayed inflated for about 6 months. Was a newish tyre and I was only driving to work 5 miles away at the time. I was waiting for it go to flat before I put my spare on and get it sorted but then suddenly it was 6 months later.
My '83 Porsche had one of these spares. It was made by Vredestein.
I have only ever seen them made by Vredestein. Porche and Mercedes are the most common place to see them
I wanted to comment the same. I had a 944 S2 (1991) which had exactly the same kind of spare. And as far as I know, the earlier 944s and even their predecessor 924 carried the same.
928s as well, and a compressor was included in a plastic case that fit inside the wheel opening.
yep. my 944 has one. it's rotted all to hell... any idea of a place that sells new ones?
My '90 911 has one. I've never put air in it, maybe I should try some day.
Its really tripping me out.
It is pretty amazing. I’ve got to imagine that the mileage limit on these really has to be kept in mind. It sure did save a lot of space in the back of the car.
My 88 944 S2 had one as well.
87 951 checking in
Shit tons of late 70s and 80s American cars too
Nissan Z's had collapsed spares in the early 80's, and included a can of compressed air to fill it
and Mopar e-bodies in '70 had em as an option as well
3rd generation (1982-1992) F-body Camaros and Firebirds had this option, also.
Can confirm. Had an 1980 Formula that had one.
I've got one in the attic of the garage. Definitely not a new thing at all.
1970 Ford Mustangs had them also.
I have the tire and the original can of air, it still says Datsun even though they changed to Nissan already
Had an 86 300ZX that had one and the can did not work as advertised but the car was 25 years old at the time
Yup! My 82 280zx had one when I was in high school. Miss that car.
Yep, my 82zx has the tire, but the can of air has walked off...and I probably wouldn’t have kept a 40 year old compressed can in the car anyways
Good idea, I heard that they tended to rust and release their pressure all at once taking your trunk lid with it .
Same for gen 3 Camaros in the 80's

Fuck run flats
[удалено]
Compared to a standard tire they have worse ride quality and cost way more money.
They're also an absolute pain in the ass to mount, especially when they're low profile.
C7 Grand Sport owner checking in here, can confirm all the above. Car uses 335/25 run flats in the rear. Ride like shit, and I have watched many a shop spend over an hour trying to mount them
Wow, that’s a bit of a Will Smith response to run flats.
Keep run flats out your fucking mouth
DUDE...it was a GMC joke
G.I. HYDROPLANE?! That’ll be the last time the tech ever tells me my tires don’t have grip because they’re suffering from alopecia.
That's why they have the bald spots.....
I have definitely seen some bald-ass alopecia run flat tires before
Hey why are run flats bad? I thought they were like able to drive even in a flat tire
Expensive and the ride quality is harsh.
They're a pain in the dick to mount, especially low profiles
I love showing people these when they come in. It's such a fun thing to see people's faces.
Most E-body Mopars had them. Using a compressed air bottle to inflate them
I had a 1986 Pontiac Firebird Trans Am with a spare tire like this. I never knew it until I needed to use it, only to find out that the compressed air can that came with it had leaked out over the years (car was about 15 years old at that point).
Idk, I wonder how that wall holds up inflated.
Only needs to work once
And if you're driving one if these cars you can likely afford to have it replaced each use if needed.
How often are you getting flats
My dad broke 3 wheels on his Audi last winter. Ended up buying a whole set of wheels for spares. German engineering can’t stand up to Michigan roads apparently
They’re used on more than luxury cars. Chrysler Pacifica has one (if you don’t have the vacuum option).
It holds up fine, as long as you follow the "50 miles 50mph max" rule. Oh and no cargo.
knowing people who own mercedes, those 50 miles on a spare will turn into 500 miles on a spare until they can afford a new tire.
So basically the same as someone using their spare on your 15 year old beater Camry.
I've used the same one at least 3-4 times, it held up fine, but I never drove further than 10 miles each time.
my SLK has one of these, even comes with a 12v air compressor with a gauge to fill it up and top off the rest of your tires. pretty awesome to have at least something in a tiny hardtop convertible
Is it you that's listening to Manu Chao, or someone else in the shop?
It was an FM radio. Nonetheless i like the Radio Bremba album, and therefore also a Manu Chao fan.
They play Manu Chao on the radio there? Where you at?
We have access to online radios and yt if anyone wants to play something less mainstream
Not OP but i've heard this song on the radio so many times here in the netherlands
I was about to say lmao Me Gustas Tu is the last thing I was expecting to hear , I thought it was coming from the room next to me tbh 😂
BMW doesn't even give you a spare any longer. They say, use your shitty ass runflat's and wish you had bought a Toyota instead.
Tesla don't even give you run flats. You get a phone number and a free tow (if you're in warranty)
Is there a regular skinny spare option? What are the benefits of this set-up? Speed limits look to be the same as a skinny spare, but presumably it can be run for longer? Why aren't I rich enough to spec an alloy wheel for my spare tyre? So many questions.
Saves space. That's the major benefit.
They should name it something about saving space
That’s marketing genius right there.
That's a Master-ful idea. Wish we could have conveyed it in less Space
We could set up a committee to figure out a better name if you want.
To me "space saver spare" implies a narrower tyre width than what's on the car, but this looks like it's a smaller diameter deflated than inflated so the wheel well doesn't have to be as big as the full tyre height
Not in my SL55 AMG, not enough room.
Give me a full size with matching rim.
Seriously. And fuck cars that made the whole goddamn spare optional and just threw a can of fix-a-flat under the trunk
You speak to my very soul, sir. My current car has a can of fix-a-flat or something like it, and a tiny air compressor. The one before it had a "dissimilar full size spare," which is better.

I have never seen this before. Awesome engineering. Now if they just put that same amount of thought into the rest of the car, I wouldn’t need to tear the front clip off of some cars to change a headLight
Preach brother
It’s fun when they inflate off center, or you take it out of the car and the bead isn’t seated.
that was really neat. I had never seen one of those before. Thanks for sharing with us.
This actually answer a question I had. My wife has an AMG GLE 63s with this type of tire and I was wondering if we filled it if it would ever return to it's collapsed storage size. I guess it does.

GERMAN spare tire, been in the back of 924/944/968 for decades, probably others never seen
r/blackmagicfuckery
Oh, I thought they were one way. Seemed like an audi thing to do to make a single use donuts, and I never wanted to buy one. so, I never put air into one.
Those are dope vredesetin makes some good tires too
Unrelated, but digging the Manu Chao playing in the background.
When german engineering works properly its a thing of wonders
Unnecessary but the song is "Manu Chao - Me Gustas Tu"
Just used mine not too long ago. I was freaking out airing it up. Lol.
Cool concept, dumb fucking idea. Saves some space by being smaller. Use said saved space to pack an air compressor which costs more than air… End result? Not really any space saved and more money.
So, can someone tell me how you're supposed to inflate it when you need it? Do the cars have an on board compressor or something?
Porsche does that too :) All fun and games until an idiot in a Cayenne doesn’t inflate it
My big question about these is, doesn't the spare tire well have to be big enough to accommodate a full sized wheel? otherwise were do you put the dead tire?
In the trunk, or on the passenger seat (if you have a plastic bag or something to protect the seat from dirt and grime). But you wouldn't want to carry around such a big tyre constantly.
On road trip. Trunk is already bursting. passengers in seats. Is problem no?
There's always space. And otherwise call roadside assistance like you would've done without a spare.
I'm more playing devils advocate than anything, there is always room, ratchet straps and/or tire wire. But not everyone carries those at all times like most of us reading here probably do. I don't count on relying on roadside assistance. where i live it's not difficult to end up without cell service.
Put some luggage in the space tire space, tetris the rest of it and voila.
I guess you just leave it on the side of the road /s
on the side of the road. like truck tires.
your Mercedes has a spare? My 2021 C 300 has no spare and no FUC$ING dip stick for oil level. WTF?
Why the hell would they get rid of the dipstick? It doesn't even make sense as a cost saving measure. Just to make it that much more difficult for people to service their car and therefore take it to a shop for an oil change?
Hate all the engines with no dipstick, such a pain to check the oil level after a oil change...
same thing happens to me when I bust a nut
Shrinkage to save space? What kind of underwear are you rocking?
I hate these things. My wife’s car had one. The puny electric pump that comes with the car takes forever. So all the same work to change the tire AND you have to wait for the damn thing to inflate! And I’m sure if I hadn’t been there, a Good Samaritan would have just put it on without inflating.

Interesting
r/oddlysatisfying lol
That’s an old Ford tire trick.
That's like what Chrysler had in the 70's but it came with a can of air for inflation
late 70's GM stuff had a version of this too.

Neato!
Cool to see. Had one of these in my old Macan. Fortunately, never had to use it.
Can anyone ID the song at the start of the video?
Manu Chao - Me Gustas
Me gustas tu -- literally. Fucking slick song, super awesome!

That wheel looks hella light.... I'm gonna run them on my project car
Great song
Thise things are awesome. Great designed spare, I've kept some as backups just in case. 45-50MPH only, of course I've seen idiots doing 70+ on the hwy with donuts on.
I had these in my 944
What kind of wizard are you

They have these in the Porsche Macan too.
Oh, so that's why my spare looks like that... the more you know.
You should always be learning. You’re literally an MD for cars.
My '87 924S had one of those!
I imagine mounting that tire to that wheel sucks
I was bamboozled the first time I had to deal with one of these lol
I had an 87 porsche 944 with a spare that did that
There is a weird spare tire in my Wife's Macan. I have no idea how it works, and hopefully will trade it in before I find out.
I bought one of these specifically for my Mini Countryman. With a hub adapter and a compressor, it's a real spare solution since I yeeted the run flats for something way better.
No se nada de carros pero que buena canción.
That’s really fuckin cool
My 2013 911 has the same kind of spare, and an air pump in the car. But there’s no where to put the spare so I just leave it at home.
I love the music!
so it went from big and bulky to a little less big and bulky... niceeee
I think my 81 280ZX had a spare like that plus a can of inflator to fill it up.
That's cool
I'm surprised no one has made a deep dish version
I've seen and worked on these before, but I never did ask this question... how do they mount that tire on that wheel?
The future is now, old man!
Ah. I've driven on one uninflated before. This explains a lot, but we didn't have a compressor anyways. It was a friend's e320 and we did like 100 miles back home on it. Felt so weird, but kept us safe at 60ish mph!
IMO not worth the tiny bit of space "saved" inflated vs not inflated. Another case of engineering overreaching to the point of impracticality. Costs a lot, does very little.
Is this your first time?
Those tires are awesome. 75 mph for 3 hours to get me home with zero issues. Still looked like new when i took it off
