I'm getting a set of 315 bfg km2s next month and am still contemplating a new set of wheels. I'm currently running 315 mt/rs on stock 16x7 5 spokes. The way it sits now is perfect in my opinion. I want an 8" rim to mount the km2s on, but want to figure out the backspacing that would best reflect the stance and position of the oem rims. Any suggestions please drop in and spill em, thanks guys.
