1984 GMC S15 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1984 GMC S15 Base rolls on a 5x120.65 bolt pattern with a 70.3mm hub-centric center bore. The truck wears 15x6 wheels at a 25mm offset from the factory. You can step up to 15x6.5, 15x7, or 15x8 sizes while keeping the same practical, non-staggered setup across all four corners.
The 5x120.65 bolt pattern is specific to your S15—no other pattern will fit safely. Because your hub bore sits at 70.3mm, use hub-centric rings if you choose a wheel with a larger center bore to ensure proper centering and balance. Wider wheels and more aggressive offsets risk interference with fender and suspension components, so stick to the compatible sizes listed to avoid costly rubbing issues.
We verify every wheel bolts directly to your truck and ship all fitments free across the lower 48 states. American Racing, US Mag 1PC, Vision, and WELD Performance are among the quality brands we keep in stock for your S15, ready to upgrade your ride.
