OK heres the deal, I thought I had a bent rim. And Im relatively sure I did, because the vibration goes away for the most part now with New AP2V2 and Tires. But I was leaving my friends house last night and it felt like I had a flat spot on my rear tires. I'm not sure how much vibration there really is anymore because Im paying to much attention to it now. My car is stock hight and has 60k miles on it. I dont take it very easy on this car as it is not my DD so when I drive it I'm usually getting on it pretty hard. Do you think I could need drive-shaft spacers?

 

When is the last time you had an alignment? Whatever bent your rim could have knocked something else out of spec.

 

Would a bad alignment cause a flat spot feeling at 4mph?

 

You could have a tread separation, even on a relatively new tire. Sometimes you can find it just by running your hands around the tread. If it's not too bad, you may have to spin the tire and look for a bulge as you watch the tread surface.
