For my 1991 P/U, what wheel offset do I need to use to fit 33/12.50s with 4" susp lift, but no body lift?

 

The way I understand it, offset is the opposite of backspacing. With 4 inch suspension lift 33"s will fit easily on just about any wheel. Your stock wheels will work unless they are only 6 inches wide, don't put 33x12.5 tires on 6 inch wheels.

I bought Genuine Totota wheels in 15x7 size and JJ backspacing (3.5 inch) to fit 33s with only 1.5 inch body lift and no suspension lift. I'll have to pound or trim the front fenders near the firewall slightly.

 

:pat: I meant backspacing So offset is measured from the outside of the wheel? I don't even know what offset is or why I used that term!
