1986 GMC S15 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1986 GMC S15 Base requires wheels with a 5x120.65 bolt pattern. The truck rolls on 15x6 stock wheels with a 25 offset. You can upgrade to 15x6.5, 15x7, or 15x8 widths while maintaining that same offset, giving you flexibility to customize the appearance without sacrificing fitment.
Pay close attention to the 70.3mm center bore requirement—wheels with a larger bore need hub-centric rings to seat properly on your truck. The 5x120.65 bolt pattern is specific to your S15; no other pattern will work safely. Aggressive width increases or offset changes risk rubbing against fenders and suspension components, so staying within the compatible sizes we stock keeps you trouble-free.
Every wheel we list bolts on securely and ships free throughout the lower 48 states. American Racing, US Mag 1PC, Performance Replicas, Vision, E5 Wheels, WELD Performance, Forgestar, and Ridler all have fitments ready for your truck.
