The Evolution of GMC AT4 Wheel Specifications

The GMC AT4 lineup was built around off-road capability and premium styling, and its wheel options evolved to support that mission. Factory AT4 packages include more aggressive tires, off-road-tuned suspension, and visual upgrades that respond especially well to aftermarket wheels.

Most late-model Sierra 1500 AT4 trucks use a 6×139.7 bolt pattern, while many HD AT4 models move to heavy-duty 8-lug patterns. Both platforms offer plenty of room for larger wheel and tire packages with the right leveling kit or lift. If you’re building your AT4 for camping, trails, or long-distance overlanding, explore our curated off-road wheel & tire packages designed for lifted and adventure-ready truck setups.

GMC AT4 Wheel Finishes

Choose from a wide range of GMC AT4 wheel finishes to match your build — from aggressive Matte Black and Gloss Black to rugged Black Milled and Textured Black designs. For more premium or custom looks, explore Gunmetal, Machined Face, Bronze, Anthracite, or Chrome options that complement the AT4’s grille, trim, and off-road styling.

Popular GMC AT4 Rim Sizes

Our most popular GMC AT4 wheel sizes include 18×9, 20×9, and 20×10, with some heavy-duty builds stepping into larger or wider options. These sizes are commonly chosen to balance stance, clearance, and performance for both stock-height and lifted AT4 trucks, especially when paired with 33″, 35″, or 37″ all-terrain and mud-terrain tires.
