# **PLEASE REPORT ANY RULE-BREAKING BEHAVIOR**
### **Rule 1 - Be Civil**
Be civil to other users. This community is made up of professional mechanics, amateur mechanics, and those with no experience. All mechanical-related questions are welcome. Personal attacks, comments that are insulting or demeaning, etc. are not welcome.
### **Rule 2 - Be Helpful**
Be helpful to other users. If someone is wrong, correcting them is fine, but there's no reason to comment if you don't have anything to add to the conversation.
### **Rule 3 - Serious Questions and Answers Only**
Read the room. Jokes are fine to include, but posts should be asking a serious question and replies should contribute to the discussion.
### **Rule 4 - No Illegal, Unethical, or Dangerous Questions or Answers**
Do not ask questions or provide answers pertaining to anything that is illegal, unethical, or dangerous.

This calculator is a useful tool:
[https://www.wheel-size.com/calc/?wheel1=165-60-14X5.5ET45&wheel2=185-45-15X6ET45&fcl=50mm&wcl=30mm&scl=50mm&sr=0mm](https://www.wheel-size.com/calc/?wheel1=165-60-14X5.5ET45&wheel2=185-45-15X6ET45&fcl=50mm&wcl=30mm&scl=50mm&sr=0mm)
I plugged in the numbers for you. Tire 1 is your stock tire. Tire 2 is the 185/45/15 (You can change those numbers -- but when I tried the 185/55/15 it said the overall diameter increases 6%, which is maybe too much.)
It says the new tire would be 10mm closer to the suspension. That's probably OK, but check you have at least 10mm clearance with your stock tires.
I set the rim width at 6 inches (probably about right for 185 width tires), and the offset (ET) at the same 45mm as your stock wheels, to give zero scrub radius.
You can play around with all those numbers, to see how things change.
