Hey Nelson I am running 31x11.5x16 Mickey Thompson Baja Belted Tires and I just had extremely minor trimming on the front fenders (back fit perfect. If you look at the front wheel well you only really have to trim that part that wraps in, and only like the bottom 3-5". It really make your car look great with the 11.5's. Probobally the best mod I have done yet! Oh ya, forgot to add that I got some Eagle alloy comets 16x10.5"
