The Fuel Contra 20x9 8x180 wheel and Toyo Open Country R/T Trail 37x12.50R20 tire package part number ful_d61520901850tyo_354210 is built specifically for GMC Sierra 2500/3500 HD trucks running 5"-6" suspension lifts. This 8-lug setup delivers an aggressive stance while maintaining proper clearance and drivability. Each package arrives professionally mounted and balanced for a true bolt-on installation.

This package was carefully assembled using our extensive fitment knowledge and manufacturer specifications to ensure proper offset, load capacity, and tire clearance for lifted HD applications. The +1mm offset and 5.04" backspacing position the 20x9 wheel correctly under the truck without excessive poke, helping maintain stable road manners while enhancing overall stance.

Paired with the Toyo Open Country R/T Trail in 37x12.50R20, this hybrid rugged-terrain tire delivers strong off-road traction with improved highway comfort compared to a full mud-terrain tire. The 10-ply Load Range E construction and 3,750 lb load rating provide the strength required for diesel-powered 2500/3500 HD trucks used for towing, hauling, and trail use.
