1983 GMC S15 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1983 GMC S15 Base bolts up to a 5x120.65 pattern with a seventy point three millimeter hub bore. The factory wheel is fourteen by six with a thirteen millimeter offset. You can step up to fourteen by seven, then jump to fifteen, sixteen, or seventeen-inch widths ranging from seven to eight and a half inches—all in square setups, not staggered.
Watch for the five by one-twenty point six-five bolt pattern; nothing else fits this truck. Use hub-centric rings if your wheel's center bore runs larger than seventy point three millimeters. Stay cautious with aggressive offsets or extreme widths, since fender and suspension clearance tightens as you go wider and pushes the wheel outboard.
Every wheel we stock for your S15 bolts on securely and ships free across the lower forty-eight states. American Racing, US Mag 1PC, Performance Replicas, Vision, and Forgestar all have in-stock options ready to ship.
