I finally order my 4" lift, and got 6 295x75x16 BFGs($100 at the swap meet!!) but for the rims I was going to go with a 16x10 but what about the backspacing? Its a 94 f150

 

stock is like 3.75" so no more than 4". most aftermarket are more common with a 4" backspacing. my truck is still stock but i went from stock 7.5" rim to 8" with 4" backspacing and didnt notice any differences. but like i said all i changed was the rims

and my 15x10s also have a 4" backspacing
