My wheels rub after install. Here's why.
You unboxed a new set of wheels, mounted them up, took the car off the lift, and heard the worst sound: rubbing. The fix is rarely "just hammer the fender." Here's how to diagnose what actually went wrong.
The 4 ways wheels rub
| Fender rub at full lock | Wheel too wide / offset too low |
| Inner fender liner rub | Offset too high (backspacing too deep) |
| Rubbing over bumps | Suspension compresses, no clearance |
| Tire stretch / sidewall touches | Tire too wide for wheel |
First: diagnose where it's rubbing
Don't start cutting metal yet. The fix depends entirely on which part of the tire is hitting which part of the car. Spend 5 minutes finding the contact point.
- Mark the tire with chalk in 4 spots around the sidewall
- Drive over a speed bump at low speed, then check where the chalk wore off
- Turn the wheel full lock both directions and inspect the fender liner
- Push down on the corner to simulate suspension compression
If it's rubbing the outer fender lip
This is the most common issue. The wheel sits too far outboard — either the offset is too low or the wheel is too wide.
Quick fixes (without changing wheels):
- Fender rolling — flattens the inner lip. $50-200 per fender. Best ROI fix.
- Fender pulling — physically pulls the fender outward. More aggressive.
- Lower-profile tires — shorter sidewall = less rubbing on bumps.
- Smaller spacers in reverse — won't help if you're running spacers already.
Permanent fix: wheels with higher offset (more positive ET number) or narrower wheels.
If it's rubbing the inner fender liner
The wheel sits too far inboard. Backspacing is too deep, or you've gone wider without adjusting offset to compensate.
Quick fixes:
- Wheel spacers — push the wheel outboard 5-25mm. $50-150 per pair.
- Trim the fender liner — cuts away plastic, doesn't affect structure. Free.
- Camber adjustment — angles the top of the tire inward. Limited effect.
Permanent fix: wheels with lower offset (more negative ET) or different backspacing.
If it's only rubbing over bumps
Static measurements look fine, but suspension compression eats your buffer. This is brutal because it usually only happens at the worst times (passengers, full tank, speed bumps at full speed).
- Raise ride height — coilovers or stock springs. Adds 10-20mm clearance instantly.
- Stiffer springs/dampers — reduces compression travel.
- Bump stops — limits how far the suspension can compress.
- Smaller tire diameter — last resort, changes gearing.

Check fitment before the wheels arrive
Our free Wheel Fitment Calculator shows poke, backspacing, and rubbing zones on a live diagram. Adjust offset and tire size before you buy.
Open fitment calculatorThe fitment formula every shop should know
Poke and tuck are both measured in millimeters from the hub centerline. To predict rubbing:
- Poke = (wheel width ÷ 2) − offset
- If poke > fender clearance: guaranteed rub
- If poke > clearance − 10mm: rubs on bumps
- If poke < clearance − 25mm: wheels sit too far in (deep tuck)
When to give up and re-spec
If you've already done fender rolling, spacers, and lowered the car — and it still rubs hard — you bought the wrong wheels. It happens. Eat the loss, sell them on Facebook Marketplace, and use a fitment calculator before buying the next set.
The cost of guessing wrong on wheels: $500-2,000 in spacers, fender work, and tire damage. The cost of getting it right the first time: free.
