I am planning on buying either 15X8 with 31's or 15X10 rims for some 33's. Or possibly 15X8 with the 33X12.5's since I heard it can be done safely.

What kind of backspacing am I looking at needing for either a 10.5" or 12.5" tire for the 15X8 rim....... or how much backspacing will i need for 33 X 12.5" with the 15X10 rim?....

Or.... what is the backspacing for the stock 16X7?

sorry.... I am special...


Any input will be greatly appreciated folks.

 

if you have a 97-03 f150 u cant put 15s on these trucks the front brakes are to big. 16s are the smallest dude.

 

you are exactly right Alberta
