Check the tires for a delaminated steel belt. Had a tire go bad once and it felt just like that. You can check the DOT code on the side wall for the manufacture date, anything over 6 years is suspect. Even if the tread looks good, an old tire can still go bad. It's not the amount of wear that matters, it's how old the tire is. Steel belted tires are notorious for going bad, you can see all the tire treads on the freeways from all of the failures.

Sorry you're having a bad day. Please read my original post I didn't say the OP did it. Hell it could have been done by the PO during a last joy ride. The OP has only owned the car for 2 months, and this was an obvious example so you could understand a bent wheel. This could be caused as noted above by an improperly installed wheel, anything that would cause the wheel to not follow a straight line.

I am a big proponent of the KISS principal and have learned to NEVER take anything for granted. Always check the simple stuff before you move to the Advanced Philosophical Mechanical Engineering (ie expensive)

In closing I recognize and appreciate the knowledge you that you share and apologize to the OP for this useless exercise. I'm out.

Did you check the car in the air for any movement. A failing control arm bushing or toe link might do this.
