1981 GMC K2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1981 GMC K2500 rolls on an 8x165.1 bolt pattern with a 117.0mm hub-centric center bore. The factory setup is a 16x7 wheel at 13mm offset. You can upgrade to larger sizes like 16.5x6.5, 17x8 through 17x9, or even 20x8.5 wheels while maintaining proper fitment and clearance on this truck.
Keep in mind that only 8x165.1 bolts will work on your K2500—no other pattern fits. Since your truck uses a hub-centric design, install hub-centric rings if you choose a wheel with a larger center bore than 117.0mm. Wheels significantly wider or more aggressive in offset than stock may cause rubbing at the fenders or suspension components, so stay within tested parameters.
Every wheel we list for your K2500 is verified to bolt on properly and ships free throughout the lower 48 states. Browse our in-stock inventory from Carolina Forged, Vision, WELD Off-Road, American Truxx, Black Rhino, Fuel 1PC, American Racing, and Tuff to find the right look for your truck.
