Hello,

I have an 05 sedan with the 18" OEM rims. Last year, I installed 245/45/R18 Goodyear Eagle F1 GS-2 tires on the rears only.

Now, the fronts have worn so I installed new tires (same brand), and rotated the tires (new tires in rear, old tires in front). All tires have 40 psi and torqued to 85 Ft Ibs. Now, I am experiencing steering wheel vibration at 65-75 mph. I got the old tires rebalanced and it is still doing the same thing.

I was thinking it was a suspension problem so I installed the new tires up front and put the old tires in the rear to check if I notice the same problem. No steering wheel vibration is noticed and there is only slight rear vibration.

What could be with the wheel? I know it has something to do with the old tires but am stumped on the problem. I would like to hear your opinions. Thanks.

 

Did the place that balanced your tires use a Hunter machine?

 

Are you running any spacers?
Is your car lowered??
