Wheel size and backspace table from Weld Racing

Came over this PDF at Summit. It shows recommended backspace for a given wheel size:¨




Original document with several different cars: https://summitracing.custhelp.com/ci/fattach/get/99/1089836847

Thanks for the info. I printed it out. JB

any idea, the recommended backspacing on 15 x 10?

5.25" - 5.5" Is what most recommend. Limey is the self proclaimed 10" king so he might know if I'm off.

My 10" rims have 4" backspace. I have to have the stinkbug stance to keep the tires from rubbing or getting cut by the wheelwell lip. 295/50 tires.

I will get another set sometime that will have at least 5.25" b/s. I'm thinking that 325's would be ok on a 10" rim with 5.5" b/s. At that tire size, the most you should have to do is roll the wheelwell lip.

FOR THE 73 - 77 15 X 10 WHEELS YOU WILL NEED A 4.5" TO A 5.5" backspace depending on the wheel maker my self will be going to a 5.5" Backspace for my rears
