1988 GMC Jimmy Base Wheel Fitment Guide — What Works & What to Avoid
Your 1988 GMC Jimmy Base runs a 5x120.65 bolt pattern with a 70.3mm hub-centric center bore. The stock setup is a 15x6 wheel at 45mm offset. You can step up to 15x7, 15x8, 16-inch sizes from 6.5 to 8 inches wide, or go 17 and 18-inch options—all bolt on square, not staggered. This Jimmy isn't picky about matching fronts and rears since it came square from the factory.
That 5x120.65 bolt pattern is the only one that will fit, so confirm it on any wheel you choose. The 70.3mm center bore means hub-centric rings are necessary if your selected wheel has a larger bore. Push too wide or too aggressive with offset and you risk rubbing against the fenders and suspension components, so stay within the compatible sizes listed above.
Every wheel we stock for your Jimmy is verified to bolt on correctly and ships free to the lower 48 states. American Racing, US Mag 1PC, Performance Replicas, Vision, E5 Wheels, WELD Performance, Forgestar, and Ridler all have fitments ready to go.
