This is so bizarre! Today on my way home, I was thinking of rotating my tires. I've been getting a little vibration, at the seat and sometimes slightly at the steering wheel. I went to my local tire shop to see about rotating and checking for bent wheels. Well, once they got the car up on the lift I saw how bad my rears were. Rims look straight but the rotation was out of the question. I have the exact same tires as the ones in your picture. Falken Ziex 512's right? My rears aren't quite as bad as yours, but I can probably only go a couple thousand miles. I thought I would check out this site when I got home and lo and behold I see this post. I'm thinking of getting the adjustable rear camber plates, they're about $270. I didn't realize I already have 25,000 miles on these tires. I only paid $400 for these tires so you get what you pay for.
