At Dave Sinclair Customs, you can choose the upgrades that make sense for your vehicle and your style—whether that means wheels and tires, blacked-out details, accessories, or other individual changes.

This 2026 GMC Sierra is a good example of how even a few carefully chosen upgrades can completely change the look of a truck.

2026 GMC Yukon Denali Ultimate | Wheel & Tire Upgrade

For this Yukon, we kept the OEM wheels and had them powder coated black, then paired them with Nitto Recon Grappler tires.

That’s one way to change the look without replacing the factory wheels.

Every vehicle and build is different. We also offer aftermarket wheel options, including Vossen rims, along with other Nitto tire choices depending on the setup.
