some guys have installed 32" on stock wheels, that will hold your offset, just pushing window on tire width on front rims. You will be a little wider in front cause tires are wider and probably slightly narrower in back cause tire narrower. To my knowledge no one makes varied sizes in 32". otherwise best bet is 7" wide x 15" diameter 6/1 offset on new front wheels and 4/3 offset on new rear wheels
