i have a 85 t-type this coming up week im going to order 15x8 weld prostars.what size back spacing should i use. the weld application guide said to use 4.5 in. back spacing but some forms on here they say to use 3.5 in. backspacing.
p.s. my goal is to be able to fit 26x10.5 mickeythompson sportsman pros. or bigger if they will fit.
