Back spacing question ???
I think I know the answer but want a little confirmation. Here's my question/issue.
I'm running a stock front frame with global west tubular upper/lower arms, stock disc spindles, QA1 big block coil over kit, and stock single piston calipers. The rim/tire combo I'm looking at is Centerline Convo Pro 15x4.0-15 with either 1.75 or 2.3125 backspacing. Tires are M/T Sportsman 26x7.5-15.
I'm thinking the 2.3125 bs is the best for this. I know 67RS502 is running 15x3.5-15 with 2.25" BS and same tire size. So I figure my combo should be ok using the 2.3125 BS.
Any thoughts ???
