1975 GMC C25 Wheel Fitment Guide — What Works & What to Avoid
The 1975 GMC C25 uses an 8x165.1 bolt pattern with a 117.0mm hub-centric center bore. Your truck rolls on 16x6.5 stock wheels with 31mm offset. You can upgrade to larger sizes including 16.5-inch and 17-inch wheels across various widths—from 16x7 up to 17x9—giving you solid flexibility for styling or terrain needs without abandoning square-wheel setup.
Keep in mind that only the 8x165.1 bolt pattern fits this C25; no other patterns will work. Since wheels with a center bore larger than 117.0mm require hub-centric rings to seat properly, verify your choice's bore dimension before purchase. Aggressive width and offset changes risk rubbing against fenders or suspension components, so confirm fitment when stepping beyond stock dimensions.
Every wheel listed here is verified to fit your 1975 GMC C25 and ships free throughout the lower 48 states. Carolina Forged, Vision, WELD Off-Road, American Truxx, and other in-stock brands all offer compatible options for this classic truck.
