1984 GMC S15 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1984 GMC S15 rolls on a 5x120.65 bolt pattern with a stock setup of 14x6 wheels at 13 millimeters offset. You can step up through compatible sizes ranging from 14x6 all the way to 17x8.5, giving you flexibility to customize the truck's stance. Since this is not a staggered application, you have the freedom to run matching widths front and rear across all available fitments.
The 5x120.65 bolt pattern is specific to your S15, so verify fitment before purchasing any wheel. Your hub centerline measures 70.3 millimeters; if a wheel's center bore exceeds this, use hub-centric rings to maintain proper centering and balance. Aggressive offsets or extremely wide wheels risk contact with fenders and suspension components, so carefully consider how far negative or positive you're willing to go on offset.
Every wheel we sell for your S15 is guaranteed to bolt on and ships free throughout the lower 48 states. American Racing, Vision, and Ridler are just a few of the quality brands currently in stock and ready to ship.
