My 2007 250 awd vibrates intensely on highway. The dealer found 3 out of 4 rims are bent. He told me because of the run flat tires, the rims are easily bent when hitting a pot holes. I did hit a few of them. They are everywhere on the road during this snow season. But I never had any rim problem with my previous cars on the same road. I should have changed those run flat tires since the very beginning.
Any suggestions for the new wheels and tires? I don't need fancy rims, just want to have something that can last longer.
