Going with the wider wheel can be iffy. You need to clear your A-arms, steering linkage and frame. Then you need to clear the fender on the outside. It could be a lot of trial and error. Or find yourself some stiff cardboard or plywood. Make a wheel assembly and bolt it to your rotor. Then turn one way and measure clearances with a tape measure. Then turn the other way, repeat. The put the "wheels straight ahead and measure some more.
