O.k. the maxima I bought at the auction has 215 60 16's. Stock rims.
At highway speeds the steering wheel shakes a little and if you lightly hold the wheel it seem s to track a little kind of like it has a mind of its own. It is annoying so I was going to replace them with the Kumho's stock 215 55 16. My question is : isn't a 215 the width of the tread and the 55 the % of the width. Therefore, a 215 on anysize tire/rim should be the same width as any other 215, correct? The tire shop tells me there's a difference in height AND width on a 215 60 vs a 215 55.. I say the 60 is just taller.. Will replacing the cheaper brand (Winston) 60 with the Kumho 55 help with my shaking steering wheel at all ?? I am aware of the known problems others have reported and wondered if maybe that was my problem and not the tires. I had the tires on it balanced and it helped but didn't rid it completely. Thanks!!

 

size seems fine.. i think they didn't balance it properly.. or maybe the car was in an accident..

 

Go to www.tirerack.com for tire size info.

Changing tires may or may not fix your vibration problem.

If you alignment is off or if you wheel/tire is not balance, it will continue to cause your problems.

 

car wasn't in a wreck. Sprint, when you say the size seems fine do you mean going to a 60 is o.k. to do?

No one still answered my question about the width...is 215 the same on all tires?
