For over 40 years, General Motors used a single 8-lug standard (8x6.5"). However, in 2011, they engineered two new metric patterns to handle increased towing capacities on their heavy-duty pickups.

1. The Classic Standard: 8x6.5" (8x165.1mm)

Also known as 8x165.1mm, this is the most common pattern in history. It was used on virtually every 8-lug GM vehicle from the mid-1960s until the 2011 chassis redesign.

Silverado & Sierra 2500HD / 3500HD
Years: 1999 – 2010
Includes all 'Classic' body styles.

Express & Savana 2500 / 3500 Vans
Years: 1996 – Present (2025)
The vans never switched to the metric 8x180 pattern.

Suburban & Yukon XL 2500
Years: 2000 – 2013
Also includes the Avalanche 2500 (2002–2006).

2. The Modern SRW: 8x180mm

Introduced with the 2011 frame upgrade to increase payload capacity. This pattern is not compatible with older wheels.

3. The Modern Dually: 8x210mm

This massive bolt circle was created specifically for the post-2011 Dually trucks to support class-leading towing numbers. It is unique to the DRW (Dual Rear Wheel) models.

Technical Specifications

Vintage Truck Note: While modern trucks use metric M14x1.5 studs, vintage Chevy trucks (C/K series pre-1999) often used imperial 9/16" or 5/8" studs. Always verify thread pitch before buying lug nuts for older vehicles.
