The wheel studs are configured for a standard factory wheel setup, but variations can occur with aftermarket wheels or different hub configurations.

Always verify with your owner’s manual or a GM dealer if you’re unsure about your specific wheel configuration.
Size, seat, and compatibility
Here are the core specifications you need to know when sourcing replacements or checking compatibility with your wheels.
- Thread size: 9/16"-18
- Seat type: 60-degree conical seat
- Number of lug nuts per wheel: 8
- Wheel compatibility: Works with factory steel or factory aluminum wheels on the 2015 Silverado 2500HD; aftermarket wheels may require different lug nut sizes or seat types
When replacing lug nuts, use OEM-recommended parts or high-quality equivalents that match the same thread size, seat type, and load rating. Mismatched hardware can lead to improper seating or damage to wheels and hubs.
Torque specifications and maintenance
Adhering to proper torque is critical for safety and wheel retention. The following guidelines are standard practice for this model, but always confirm with the vehicle’s manual or GM service information if you’re unsure.
- Recommended torque: approximately 140 ft-lbs (190 Nm) for factory wheels and typical configurations
- Re-torque after installation: recheck lug nuts after 50–100 miles of driving
- Torque method notes: use a calibrated torque wrench; avoid anti-seize on wheel studs unless specified by GM, as it can alter the effective torque
- Ongoing checks: periodically inspect lug nuts every 5,000–10,000 miles or after heavy off-road use or impact events
If you’re using aftermarket or non-OEM wheels, follow the wheel manufacturer’s lug nut size and torque specifications. The correct combination of thread size, seat type, and torque is essential for safe and reliable wheel installation.
