So I have aftermarket rims on my car and the change in tire and rim size to 20's all around has altered my traction control at higher speeds. I have 305 25R 20's on the rear. I don't want them any wider if I don't have to, but I would like them taller to help offset this problem and fill out my fender well. Would increasing to a 315 35R 20 reach my goal or would it not work. Thanks for your suggestions.
