I've got black procomp steel wheels 15" and 4.5" backspacing...
now, I'd like some tire size/brand suggestions.
all I hear is 30" tires would work.
but with the back spacing of these rims, I wanna know what's the largest I can go without problems.

with stock hgt i think 30 is the limit, and you most likely will rub
i did a 1.5 t-crank and 2" body lift to fit 31's....even now with alll the lift i have done 33's required trimming.

 

3"BL 1.5"tb 32's with major trimming, and rub frame at full lock with 4.5" backspacing


30's to be on the safe side, 31's if you don't mind a little body re-working

I would recommend buying a cheap 'test fit' set before forkin out the dough on a new set, heard lots of people having problems doin over a 30".


the 4.5" backspacing will push your tires outwards 2" or so.

 

very cool thanks guys
