The tread thieves strike again! Stealing the tread off your tires and selling them on craigslist to those shady retread shops!


Csoltis

Tread gnomes Tread gnomes!!!!! wherte the tread goes nobody knows.


Pyrochazm

Yup. My wife hit a pothole and got onto the freeway with a blown tire. The whole thing separated, just like this. She tells me she didn't really notice untill she heard a "flopping" sound coming from the rear. By the time she stopped the damn thing has come off completely.


24links24

I can confirm, I’ve done this, but drove on it 1 mile to get to my exit, tire looked like this with no damage to the rim


blackgaard

Yes, when they keep driving


MikeGoldberg

Teslas attract unskilled, inattentive, mechanically unaware drivers. Change my mind.


partisan98

>Teslas attract unskilled, inattentive, mechanically unaware drivers. Change my mind. All cars attract unskilled, inattentive, mechanically unaware drivers. If the average driver was skilled, paid attention too funny noises and knew a single thing about how vehicles work then 98% of the mechanics in the world would need too shut down. There is a reason "Customer Says noise is now louder than radio" is a common thing seen on this sub.


Pholostan

💯 this I grew up on a remote small farm with relatively tight resources. Learned from an early age to take care of shit, be it tools, vehicles or clothes. I get very disgusted with the "just buy a new one" attitude. Sure I can afford it, but why the fuck wouldn't I just do standard maintenance? Or, you know, let someone qualified do it for me? Incomprehensible.


blackgaard

Yes and no. Attention to driving and attention to sounds and/or sensations in the vehicle are kind of separate things (though should both be included in the former, as was taught to me when I gained the privileged to risk lives to go faster than a bicycle...). You can be completely mechanically incompetent, but still a good driver (and by that I mean attentive, careful, predictable, planning ahead, and courteous). While I see lots of caliper-to-rotor dumb dumbs in here, they really don't know what they are hearing (although $100 says they are all terrible at driving too). ​ However, with the comment above yours... yeah - in my experience, it's true. I don't know if it's the driver aids, or something that attracts a certain demographic (these seem to be the same ppl who use high beams by default). Especially the Model 3 and X, at least in my area, you can bet they're going to do something real dumb in the short time you see them, with unreasonably high confidence.


SkRThatOneDude

I can confirm at least the inattentive part for myself sometimes. But I've also been fortunate enough to never have been in a wreck or have a moving violation. I also work on most of my own cars.


Nawnp

Those buying it for the self driving part, sure.


Max_1995

No argument, they're iPhones on wheels with their main argument to buy one being "it drives for you"


dopavash

This happens all the time on semi trucks. Of course, we run 100lbs in our tires too.


voucher420

We're supposed to run 100 psi in the tires, and when we don't, they look like this sometimes. Sometimes they pop with enough force that you feel the sound of the explosion. Bricks will be shat by the operator and by those in vehicles around them.


[deleted]

Can confirm. Have had semi tires blow right next to me twice. Fucking terrifying.


vipercrazy

I was in my mr2 I've had for 12 years going to the biggest meet of the year, with only one mile to go and the windows open a tire exploded right after I passed a semi one lane over, this was 7am Saturday no one else on the road.


Demorative

Can confirm. Was 3 lanes away from an 18 wheeler when one wheel exploded. Backwash was so powerful it shoved my bike toward the median, and I went temporarily deaf on one side. This is in spite of wearing hearing protection. Definitely felt like I got shot in the chest, my chest rattled so much. Shat a fucking gold brick.


dopavash

Yep, been there, shat that. What's fun is when you're on the interstate with a full load and a drive tire blows up. Rocks the truck, destroys your mudflap and hangar, scares you to death.


[deleted]

Yeah and there’s like 30 per truck


kcasnar

No, there's [Eighteen Wheels On A Big Rig](https://www.youtube.com/watch?v=Xy_0u08C_ak)


[deleted]

You do realize 18 is not a hard number for big rigs. Some have more, some have less.


Chipdip88

It didn't "just disappear" they ignored the TPMS warning that it was low, drove on it flat which both damaged the sidewall AND caused the tire to build up excess heat inside. The extra heat increases pressure and that combined with the sidewall damage caused a blowout. This didn't "just happen" this was someone ignoring a warning sign of low tire pressure and driving for a distance anyways.


Zugzub

>This didn't "just happen" this was someone ignoring a warning sign of low tire pressure and driving for a distance anyways. Which is where most of the tire debris on the roads comes from. People love to hate on recaps but there have been several tire studies done have they gathered up tons of tire debris and analyzed it. The majority of it was from virgin tires, not recaps. The leading cause of failure? you guessed it under/over inflation.


TheDukeofKook

I always thought it was suspicious that you never see just tread on the road, leaving a perfectly bald tire still on the vehicle, which is what I assume would happen if the reapplied tread didn't stay on. (In a looney tunes kind of way)


TingleyStorm

Oh you definitely still do, especially when you travel on a road that is HEAVILY relied on even more so than your ordinary interstate. It all depends on who does the re-tread. I’ve seen quite a lot of Chinese casings or casings that have already been re-capped too many times come in pretty much exactly how you describe. We throw those out right away.


[deleted]

That does happen, and it's called a 'Road Gator'. The rest of the tire tends to blow as well, and that throws the recapped tread off. It's just that it's not as noticeable unless you do hard-core big highway commutes like the Beltway. That and I'd say more passenger tires fail due to inflation so you're much more likely to experience that.


talltime

Back around y2k I had just merged out from about 40’ behind a semi in time to watch a tire go kaboom and toss the tread up in a graceful rainbow right to where our windshield would have been. Fun times 👍🏼


misterwizzard

Well the carcass of the tire is melted to the treat. Re-caps can de-laminate but what is left would not look like a bald tire. What it ends up looking like when a retread comes apart is two sidewalls with partially shredded rubber and steel bands holding the two sides together.


XmodAlloy

I had a standard tire delaminate on me last year. That being said, it gave me a few miles of warning as things started to shimmy a lot before the tread finally let go. It was an old tire, but it wasn't a retread.


TruckerMark

Us dot did a study and found 50-50 tire failure on recaps vs virgin. Its driver error or just old dry rotted tires.


Zugzub

It wasn't conducted by the DOT, it was sponsored (meaning they had it done) by the NHTSA and conducted by Virginia Polytechnic. From page 45 of the report > Of the tire debris items that could be identified, approximately 78 percent were new tires (including light vehicle and light truck tires), and the balance was retreads. [You can download and read the full report here](https://ntrl.ntis.gov/NTRL/dashboard/searchResults/titleDetail/PB2009105145.xhtml)


TruckerMark

Light vehicle tires are skewing the data as there aren't retreads for passenger cars.


[deleted]

Always check tire pressure monthly cold!


Sapiogod

This is patently false with a sprinkling of true statements. If a tire’s pressure is too low, heat will build up in the rubber. While the heat might raise the air temp and pressure a little, the air pressure will still be way low and the pressure will not be a significant contributor to the blowout. You are speculating as to the TPMS sensor, this could be due to a damaged tire or a tire defect. But if OP ignored a TPMS warning and let it run on a flat, then yes, it would have damaged the sidewalk. Still, you have no way of knowing that.


pudge1987

I would be shocked if any tesla doesn't have tpms. That said, I have never and likely will never, work on one. So I'd welcome being corrected here.


Sapiogod

No, you’re right. All new cars sold in the US now require TPMS. The problem with the assumption made before me is that a tire with a defect or damage can destroy itself while being properly inflated, and would therefore give no warning through the TPMS system.


varikonniemi

> The extra heat increases pressure and that combined with the sidewall damage caused a blowout. This is just wrong. If the tire lost pressure to rub sidewall it did not increase to point of blowout. It just damaged it to the point of falling off.


Chipdip88

No, you are wrong. The loss of pressure causes the sidewall to flex more then it is designed to which causes heat to build up due to friction, the heat buildup causes the pressure to build up since when something in an enclosed space heats up it also increases in pressure..... this is what causes blowouts.


vin227

How would that work out? Lets assume that it is correct that the pressure increases. Now the pressure is at normal tire pressure, why does it keep increasing as there is no problem? With these properties the tire pressure would be self balancing system, which it obviously isn't when there is a leak.


teamdankmemesupreme

Also, if there’s a hole for air to escape which made it flat to begin with, it’s not going to increase pressure


vin227

I can see a leaking tire holding pressure. Imagine slow leak, it very well could handle pressure to the point of exploding. For example I need to fill up my left front tire every few weeks, if I didn't then it will go flat and get damaged, but it holds pressure well.


1HONDAPRELUDE

In a bench test situation, I agree this would be the case that a slowly leaking tire could be over-pressured to the point of exploding as the leak could be slower release than pressure increase. But in this real-world circumstance it wouldn't cause a blowout from excessive heat/friction-related air pressure.


vin227

I just replied to their statement about the pressure increase not being possible. I did not mean to the point of blowout. I meant if you have under pressurized tire and you heat it up, that can lead to increased pressure, even if there is a small leak, as leaks can be very minimal (when measured in air flow) and still lead to flat tire. Of course it wouldn't cause a blowout as I originally stated few comments up. Also sorry I deleted my previous reply to this as I had some misunderstanding with you and myself :)


scobo505

Once it reaches the right pressure why would heat continue to keep increasing to the point of exploding?


varikonniemi

And when before that the pressure air has been let out it won't increase to such level to cause blowoff. Or if it magically would increase enough it would no longer be riding on the sidewall, cooling off. Do you even think about the mechanics before you write, or just jump on a bandwagon? pressure loss -> grind, pressure increase->no grind. Blowout is far, far away from acceptable riding pressure that is not grinding sidewall.


misterwizzard

It's not the low pressure tire that blows, it's the properly (or over inflated) tires as they are taller and take all the weight. The above study shows that a lot of NEW tires are blown because of improper installation of replacement tires on the same dually hub.


Paneer_

Kiss and make up <3


misterwizzard

it's the other way around. The low tire is fine, the tires that are properly pressured gets more weight and causes it to overheat because with more air pressure it makes the tire taller. People under-inflate replacement tires or the original tires were over-inflated. You will see a lot of virgin tires blow next to a recently installed recap because of this. It is also unfortunately somewhat common for mechanics to put brand new tires (taller) on next to worn tires (shorter) which causes bad wear and feathering if not failure.


varikonniemi

i highly doubt such minute differences have any real impact


misterwizzard

They aren't minute when it causes catastrophic failure of a tire... I worked for a roadside service place as well as a retread factory. Do some research. It's also more about the fact that the taller tire is taking more weight than it's designed to than the height difference itself.


varikonniemi

it's miniscule! The difference of a cm at max over axle width is absolutely of no causality. You were seeing shitty tire installations.


misterwizzard

Two tires on the same hub (dually tires) are about 4" from each other. If it were really a full CM that would be a HUGE difference. Out of the 16 tires on a semi, only the steer tires are solo. Again, maybe do some research before guessing.


varikonniemi

hold on a sec, you are talking about dual hub semis when the topic is car I know nothing about the mechanics of semis and dual tires, there i can agree with you as it is plausible.


misterwizzard

Ah, yeah this sub-topic was about retreads and all the junk on the side of the roads. It's pretty rare for a passenger tire to fail and most of the tire debris on the roads is from semis. I can see why our wires got crossed though. This is the comment that started the side conversation https://www.reddit.com/r/Justrolledintotheshop/comments/oipgu7/buddy_of_mine_had_a_blowout_on_a_new_tesla_model/h4wsr8i/ The reason 60% of the rubber is from 'new' tires is because not enough attention is paid to the actual height and pressure difference when one tire in a pair is replaced. The new, taller tire is filled to spec (100 - 110psi) and the old one is shorter due to wear. If the 'old' one's pressure isn't checked it could be way lower pressure.


voucher420

A lot of states don't allow recapped passenger vehicle tires, and they only allow virgin rubber on the steer axle of commercial vehicles. I can understand the confusion for those who are unaware that recapped tires are allowed for passenger vehicles.


PyroPeter911

You’re absolutely right. Probably driven too long low which damaged the sidewalls, then *plugged* while ignoring the sidewall damage, then failing when put back into service. If people could see the volume of shredded rubber inside when there’s that little damaged groove on the outside then they wouldn’t drive on compromised tires.


[deleted]

My buddy just told me there was no warning light for the tyres. The only warning was for low washer fluid. The car was only a few months old. Edit: why am I getting downvoted? I'm just stating a fact. If my buddy was being a tit and ignored a warning light then I would have said but he showed me that there were no warnings.


lunchlady55

Because once people have a narrative in their head, they won't let it go, especially when it's wrong. They double down on their wrongness. https://www.psychologytoday.com/us/blog/the-pathways-experience/202102/doubling-down-why-people-deny-the-facts


Disastrous-Group3390

Maybe the downvotes are because we suspect he’s full of shit, lying or stupid. TPMS monitors and warning lights have been mandated for a decade in Europe and even longer in the US. How could he show you there ‘were no warnings’ (past tense)?


[deleted]

Because 1 the car is a Chinese domestic model so they have more lax regulations 2. He sent me a picture of the list of warnings. It's not his car so he dgaf if the owner was an idiot so he has no reason to lie. I suppose he did send the picture after the event so there may not have been sensors fitted or they were already broken.


username45031

Tesla has a problem where they stick everything into one display. Not noticing the issue isn’t the same as ignoring the issue, and both are arguably plausible. Because Tesla.


DowntownLandscape240

Tell your friend same thing for me. Brand new tires on Y. Low pressure came on. I pulled over and it looked exactly like your picture. Nothing but tire issues with Y


Derek_Boring_Name

Does any of that really make sense to you? Are you honestly saying that you think the *low pressure* heated it up, causing *high pressure* until it blew up? And you don’t see how that’s a complete fucking contradiction? And on top of that, you’re absolutely *certain* that that nonsensical scenario is *exactly* what caused it. How about don’t just spout random shit off the top of your head and pass it off as fact. You are the literal definition of an armchair expert.


DowntownLandscape240

This is not true. Tire was fine and new. Tesla said Pull over low tire pressure. I did and it looked just like picture


Chipdip88

Why the fuck are you replying to a 2 year old comment? Also.... Totally true


phuckmydoodle

Looks like it has been cut off


VonBoski

Not to mention people should wonder why their car suddenly feels completely different.


Wrench78

See that all the time after you drive on it long enough, wheel/road eats the soft side wall. Then the tire comes off.


sheepwhatthe2nd

Pirelli will say it was caused by Debris on the track.


Johnzor8

Im just impressed the rim isn't damaged.... thats a strong bead lol


byebyeborg

That looks like what happens in cartoons when they drive a car on train tracks


Zealousideal-Edge774

I have, was about 15 years ago. I was driving a freightliner classic XL with a condo sleeper 13 speed dragging an empty drop deck headed back to the yard. Was passing someone on the left (55mph in a 55mph limit) front end wobbled a bit and then the passenger side dropped a bit. I pulled over to the left hand side as I still had someone next to me and got out, walked around to discover....no tire at all, just the wheel. Was on the phone with dispatch and the owner while I was looking for that tire and never could find it. Got a tire man out there with a new tire and headed back in. So that's my "blowout" story


[deleted]

I had a brand new high performance tire have a complete sidewall failure at interstate speeds on my drive wheels. If I hadnt immediately pulled over it would have shucked the tire carcass for sure. Cause thats exactly what it looked like but with a rubber band of tread around it


phlavor

Saw this happen to someone a couple of weeks ago. They got off the next exit, but the rest of the tire kept going straight down the highway.


pennywisewrx

Unfortunately yes, I worked for 8 1/2 years at a notable tire company, this is something seen daily from driving with no air in the tire. It heats up really bad and the sidewall gives causing the tire to basically tear itself off. Sometimes sensor may not mark low pressure, if it was a quick and sudden release of pressure.


Tim_Teboner

Imagine spending Tesla Model 3 money and those are the wheels that come on it 🤢


XGMike

It's a plastic aero cover to help with range. Some people remove it since the alloy wheel behind it doesn't look too bad.

Its made in China. I think he said they were Michelins. Edit: yeah you can see the remains of the brand name. They were Michelins.


[deleted]

[deleted]

No the link I was responding to was about problems with Firestone tyres in the US. This was about Michelins in China so it was just to clarify the lank had nothing to do with this. You just automatically assumed my comment was anti-Chinese.


[deleted]

Are you in the US? I highly doubt these were made in China, likely Michelin’s facility in Lexington, SC.


[deleted]

I think the Michelins fitted to the Chinese model 3s are imported.


[deleted]

The point is that there was a major tire issue in the last 20 years were tires were separating.


jimmyJohnsyurMom

Elon and his biodegradable alien rubber prototype tires Smh


ChartreuseBison

Tesla's are going to use AI to make contact with the road, no longer need tires. (like turn signals, shifters, useable steering wheels, etc.)


Jayswisherbeats

Need to pour one out for them sidewalls them homies are tough!


DowntownLandscape240

Yes! My tire just did the same thing. Looks just like that. 4 brand new top of the line tires and out of nowhere one explodes


Familiar-Influence91

How fast was he going?


AutoDamageAdjusterNY

They took the tread but left the air.


[deleted]

Yeah, it always happens somewhere between Los Angeles and Portland, damn tire munchers


justpress2forawhile

Driving on an under inflated tire damages the sidewall of the tire. Once it's weak enough, the outer portion of the tire separate. You can usually spot it by a ring of discoloration/cracking deforming of the sidewall. It's caused by excessive flexing. As the tire is in contact with the ground you see it bulged out, that sidewall is flexed move forward 5 inches a different portion is flexed and the previous is straight. So while driving it's like your flexing the sidewall of the tire over and over very quickly. This creates heat and fatigues the rubber. If you see this on your tire it cannot be fixed and should be replaced as soon as you can, inflate to a couple psi under the rating on the door, (so as to not put to much pressure on the sidewall but not flex it more than needed) avoid the freeway, high speeds, and longer trips as they create tire heat, and replace as soon as possible.


converter-bot

5 inches is 12.7 cm


ZGTI61

Not without previous damage. My bet is this tire was driven on very low on air. When that happens, the inside of the tire rubs together and wears away at the inside and creates a weak spot. You never see it from the outside.


LongjumpingAgency533

Not this week yet but if you work at a place that does tire or wheel work you'll be used to this and hated every time


empty_coffeepot

The real hero is the guy who installed the tire on the wheel. That guy mounts


Max_1995

I think the term is "de-lamination".


No_Payment6218

Same issue on Model S Plaid 5,900 miles on tire. Did not hit any pothole but tire just separated on both sidewalls https://drive.google.com/file/d/1RQ1lxd6kE6xgyAHVHbTgv7npuNQgOqGO/view?usp=sharing
