Re: 15x8 Wheel options 71’ K10 Backspacing

3 and 3/4” is the most common. You seen 3.5” sometimes and I think my Centerlines were 3 5/16” ?

Personally, I prefer at least a 9” rim for a 12.5” wide tire and I prefer my backspacing to better maintain factory steering geometries. I still run 15’s on several Jeeps, but prefer 17’s on a full size GM. 17x9 with 4.5” backspace and 33 12.5 would be a great combo IMO.
