if i dont want to rub my caliper which situation would be better. 15x8 with 3.75bs or 16x8 with 4.25 bs. i know the bigger the number the closer it is to the caliper but just wanted to see what you thought. the guy at 4wp talked me out of the 15x8 into the 16x8 but now i think about it , it doesnt make sense, dont i want the smaller backspacing??
