Running NeSmith, what tire sizes are people running on all 4 corners? Running the D21, there is the 28.5 which has the groove that goes at an angle across the tire, Im assuming people run those on the fronts. Theres the 88, the 90 and 92. Are people running the 88 on LR and 92? How much stagger does this give compared to running 90 LR and 92 RR?
