I did for a short time. While I liked them at first, I began to regret going down to a smaller size. Tires are a little harder to find, and you cannot use an aftermarket brake kit such as the Dynatrac ProGrips. I also noticed that my ride was rougher with the wheel/tire combo I had. I swapped back to some 17s and am happy with them.
I did, on a 2 door. It was cool how much bigger it made the tires look, in relation to the wheel, and I had no problem with them. On this 4 door, I went with 17" aftermarket wheels, because one day I may want Dynatrac Progrips.
