Im planning on buying a new set of tires and wheels. The tires are going to be 31x10.5r15's. The wheels are going to be either 15x8 pro comp 98's or 52's, can't decide yet. I'm wondering what is the proper backspacing so that i get 0 rubbing even at full turn? They will be on a stock truck but plan on getting the springtech spindles in thefuture.

 

3.75 or 4 should work perfectly

 

3.75, which is what mine are, and no rub.

 

the lower the number the more the wheel sticks out? or is it the other way around?

 

correct. the smaller the backspace the farther the wheel will stick out.

 

thanks for the help. Also does anyone know if center caps come with the procomp rock crawlers? cause i know the cragar's don't.

 

what size tire are you currently running?

 

235/75
