Not sure why you would even want to do this as wider or higher wall tire's may effect the overall handling of the vehicle as well as throw off your speedometer. If you want to do this to make the car look more beefy as it were, you should put on a set of 18" rims with 245/45/18 tires, this will look sweet !!!!!!!! 18 inch is about it. I have 18's on and they do look goooooooood.
