GM01

RTX GM01 - Monoblock Truck Wheel for 6x139.7 Rigs

The RTX GM01 is a monoblock wheel built for full-size trucks and SUVs running the 6x139.7 bolt pattern. Its clean, structured face and deep-diameter stance suit half-ton pickups and body-on-frame SUVs that want a bolder look without leaving the RTX lineup. It sits alongside the rest of the RTX range as a straightforward, large-diameter option for stock and lightly lifted builds.

Sizes and fitments stocked

The GM01 is stocked in two diameters, both 9 inches wide, both at +25 offset on the 6x139.7 pattern:

  • 20x9 +25, 6x139.7 - the everyday size for trucks staying close to factory ride height, as seen in the 20x9 Gloss Black.
  • 22x9 +25, 6x139.7 - the larger diameter for a more aggressive fill, like the 22x9 Gloss Black.

The +25 offset works on common 6x139.7 platforms; run the numbers on the fitment calculator against your truck before ordering. You can also browse the wider RTX 5x114.3 and RTX 5x112 options if your vehicle runs a different pattern.

Finishes available

Two finishes are stocked. Gloss Black is the understated choice and pairs with the broader selection of black RTX wheels. Chrome / PVD is the brighter, mirror-style option - see the 22x9 Chrome/PVD or the 20x9 Chrome/PVD, and the wider chrome RTX range for reference.

Price and who it suits

The GM01 runs from $316 to $498 per wheel depending on diameter and finish, with Gloss Black at the lower end and 22-inch Chrome/PVD at the top. It suits truck and SUV owners on the 6x139.7 pattern who want a large-diameter wheel with a choice between a subtle black or a full chrome look. Financing is available at checkout through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance, with zero-down and no-credit-needed options.

Other RTX models to weigh

If the GM01 isn't quite the face you want, the Crush and Stag offer different truck-oriented spoke designs, while the Spark and Blaze lean toward sportier looks. The Force and Thunder round out the lineup with alternative styling for the same kind of build.
