You realize that the diameter of your rear differs by 4.3%? In other words if you are traveling at an indicated 100 mph one of your wheels will rotating at 100 mph and the other rear will be traveling at 95.46 mph (or 104.54 mph).

I would correct the problem if I were you.

Aside from how your car tracks down the road, handles on the road, or stresses your current alignment(or lack thereof)...not to mention tire wear or weight balance through dynamic direction changes, then, no.

Just out of curiousity, which side is the 35? If it's the right, perhaps Your car might make a good nascar candidate.

Honestly, It's a question with an obvious answer. If you had a $300 85 chrysler lebaron daily winter beater, you might not give a ****, but c'mon, think about it.

I got an 18inch rim on the left rear and a 19inch on the right rear...in front I got a 17 inch on the right and a 20 in on the left.....do you think this will effect my ride????

VGM911

It all depends.....are the wheels on the driver's side of the car turning counter clockwise?

programmatore

It will most certainly affect your ride. Mismatched tires will have a negative effect on your ride.
