Rims & Tires
 

Fellows, I have a 92 GMC Sierra regular cab. I am in the market for some wheels and tires in a 20x8.5 (F) and a 20x10 (R) but my question is what backspace do they need to be for a perfect fit with no scrubbing and the clerence with turning or anything.:gmc2:

As far as tires I was thinking 245-45-20 for the F & R

Re: Rims & Tires
 

Are you lowered? If so, how much?

I ran a 20x8.5 w/ 5 3/4" BS and a 20x10 with 6" BS on my bagged 94.

Those are 245/35 & 275/35.... tire size will again on what drop you have.

By the way the drop of my truck is a 2/4

Hey Jwall, did you have the fender lips rolled or custom inner fenders on the front? Im about to take my truck to 5/7 static with those size wheels and trying to figure out a good BS to avoid rubbing while turning. Mine has stock inner fenders with a rolled lip.

Re: Rims & Tires
 

I had rolled fenders and modified (basically none) inner fender wells.
But you should be able to keep your factory inner fenders @ 5/7.

Re: Rims & Tires
 

Would you recommend the BS you have or a little less to keep from rubbing the inner well while turning.? Yours look like they stick in pretty far (i guess they have to be if the truck is bagged). I think I remember somebody telling me 5.0 worked good on the front with 5 inch drop but I havent measured anything out yet.

I'd go with around a 5 1/2" backspacing
