So I purchased my first Wrangler 2 months ago. When I bought it the Jeep had 35 x 12.50 15 tires and a 4'' lift. With it only being a I4 I decided to drop the tire size. I just installed a new set of 31 x10.50 15 tires on some stock Jeep rims I bought. I believe that they are 15x7. I never had a problem with the bigger tires but now when I turn sharp in the parking lot they rub really bad. They do not rub anywhere on the fender/body but rather on the frame or suspension. Anyone know why this is? Also when I first get the Jeep up to 50-55mph is starts shaking like crazy. I mean very violently
. Usually this goes away after a few miles. It cannot be the tires because I had those balanced. Please help me!!!
