well usually about 1.5-2 inches...Not much cuz then your limiting factor will be the stock wheel tubs...I think it might be difficult to get a 10 inch wheel without doing both...
i think with the right offset and backspacing its possible right? i mean right now i have a 8 inch rim but with 275 60 15 and i have a 1 inch spacer /adapter(to make my rear big bolt) so i want to fit a 295 50 15 or 295 50 16 also wanted to tuck them and drop the rear down with a 1 inch lowering block
