Choosing the right wheels can completely transform the look of your OBS truck. But fitment matters — the wrong offset, bolt pattern, or diameter can cause rubbing, handling issues, or even damage.
OBS Chevy and GMC trucks use a 5x5 (5x127mm) bolt pattern for half-ton models and 8x6.5 for three-quarter and one-ton trucks. Make sure you know which one you have before ordering.
For a lowered street truck look, 20-inch wheels with a low-profile tire are the most popular choice. Aim for a wheel width of 8.5 to 10 inches with an offset between 0 and -12mm for proper fitment without spacers.
For a lifted or off-road build, 17 or 18-inch wheels with more sidewall give you better ride quality and off-road capability. The additional tire sidewall also protects your wheels from trail damage.
Stock height trucks look great on 18s or 20s. The key is matching the tire size to your fender clearance. On a stock-height truck, avoid going wider than 285mm on the rear or you'll likely rub at full compression.
Pro tip: when shopping for wheels, always verify the backspacing measurement in addition to the offset. Two wheels with the same offset but different widths will sit differently in the wheel well.
Brake caliper clearance is another consideration, especially if you've upgraded to disc brakes. Some wheel designs sit very close to the caliper — always check minimum clearance specs.
We carry a selection of wheels specifically verified for OBS truck fitment. Each listing includes offset, backspacing, and recommended tire sizes for your specific truck configuration.
