as far as rubbing, i have 17" rims that are 7.5" wide with KDW G force 215-45-17's on them. no problems with them so you sould be fine with 225's but you will have what i call the "baloon effect" on your tires. my sidewalls are flat and are stiff and it rides very nice. i currently have stock suspension but i have all the springs and such ready to go on in the spring after the snow is done.
