Curious why you would choose this over a factory setup, 315/35 rear and 275/40 front?

As stated by qsilver, this is the factory size which is located on your door seal. 9.5"x20" and 10.5"x20" are stock wheel size. The only thing left is offset which has nothing to do with tire diameter.

Basically because the tires that are on the rims now have between 7 and 8mm of tread. Mine doesnt have the wider wheel opening trim in the back so also concerned that 315s would stick out to much. These look spot on.
