i was wondering if anyone out there knows what kind of backspacing i would need to run a 15x8 wheel on the back of a 86 mustang? its been switched to 5 lug and i see all different kinds of backspacing on wheels and im not sure which it is that i need. i will be running a 26x10.50 tire on the back. and does it make any difference on the backspacing on the front if im going to be running a 15x4?

 

anyone?

 

what kinda backspacing is anyone running with that kinda wheel?

 

Running 275 50r 15 on draglites with 5.5 backspacing hope this helps.
