I really think that one of them came from a different mold and that because its height is different than the rest its actually causing the car to pull to one side while accelerating.

I'm going to bring it to a tire dealer this week and have them order me some new kumho MX's for the rear.
The question you need to answer is whether or not they are both on the 16x7.5 wheels. It's stamped on the inside of the spoke. I suspect one 225 is mounted to a 6.5 and the other is on a 7.5 wide rim. This would explain how the same tire is taller on one side than the other, and also explains the torque steer.

Well I've figured out the problem I believe. I filled my tires up 2 weeks ago to 32 psi so I didn't even think to check tire pressure. Turns out the passenger rear tire somehow lost 12 psi.

I checked to see if perhaps it could be what your telling me bky but they all seem to be on the correct corners.

I think this is the last set of kumho's I'll get after having 2 bad experiences with them, first one being bulges on all 4 tires sidewalls when I had the aftermarket wheels.

Tire pressure was going to be my suggestion. I had the same problem once. Glad to hear you found the problem.

Lost 12psi in 2 weeks? Unless you hit a monster pothole, I think you might have a different problem now.. like a leak

I've had a couple sets of kumhos on different cars, never a problem. Maybe it was the place that mounted and balanced them. Also please check your wheels. Make sure the tires were mounted on the correct wheels as that could cause every problem listed so far.

Grrrrrrr.... that has happened to me before. They didn't screw up the rims, but didn't notice that I was using 205/55/16 on the front and 245/45/16 in the rear. A 205 looks kinda unhappy on a 7.5 inch wide wheel.

The other mechanics pretty much stood around my car and made fun of the poor tire guy while he fixed his mistake. It made me sort of glad that I was really nice about it, because his co-workers gave him hell.
