The size of the lug nuts is an important consideration, as they need to match the wheel's lug bolt holes to ensure a proper and safe fit.

Importance of Proper Lug Nut Size
Using the correct lug nut size is crucial for the safety and performance of a vehicle. Lug nuts that are too small may not provide enough clamping force to securely hold the wheel in place, potentially leading to a dangerous wheel separation. Conversely, lug nuts that are too large may not fit the wheel's lug bolt holes properly, also compromising the wheel's stability.
Checking and Maintaining Lug Nuts
- Regularly inspect the lug nuts to ensure they are properly tightened to the manufacturer's recommended torque specification.
- Use a torque wrench to tighten the lug nuts to the correct torque, typically between 140-170 ft-lbs for a GMC 3500HD.
- Replace any damaged or worn lug nuts immediately to maintain the wheel's secure attachment.
