Looking into getting a set of 20" Ultra Goliath Wheels. They have two sizes the 20 x10 and the 20 x 9, besides one being and inch wider what is the better size for my 05'2500? I tow a lot and as of right now i don't have a lift. Will either ride better than the other or affect performance? I'll most likely put on a 285/50/r20.
