RTX Oak: Monoblock 6x135 Truck Wheel in Gloss Black

The RTX Oak is a monoblock truck and SUV wheel built for 6x135 platforms, with a clean, structured spoke face that fills the arch without overstyling. It sits within the wider RTX lineup as a straightforward, blacked-out choice for full-size trucks and SUVs that run the 6x135 bolt pattern. If you want a durable daily look with a single-piece build, this is the model to start with.

Sizes and fitments in stock

The Oak is stocked in 17, 18 and 20-inch diameters, in widths of 8.5 and 9 inches, all at a +30 offset on the 6x135 bolt pattern. Concrete examples: the 17x8.5 +30 is the compact end, the 18x9 +30 steps up diameter while keeping the same offset, and the 20x9 +30 is the largest fitment offered. Because everything runs +30, the stance stays consistent as you move up in diameter. This is a 6x135-only wheel, so it suits F-150 and similar full-size platforms that use that pattern; run your numbers through the fitment calculator before ordering.

Finish

The Oak comes in Gloss Black, a deep, uniform finish that works on light and dark trucks alike. If you're weighing other colorways across the range, browse black RTX wheels, gray RTX wheels or bronze RTX wheels to compare.

Price and who it suits

Oak pricing runs from about $216 for the 17-inch up to roughly $330 for the 20x9. That puts it in reach for truck and SUV owners who want a genuine gloss-black upgrade without stepping into premium money. Financing is available through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance at checkout on the financing page, with zero-down and no-credit-needed options.

Other RTX models to compare

If the Oak's face isn't quite your look, the RTX Stag and RTX Trek are alternative truck-oriented designs worth a look. For sportier, car-focused spoke patterns, the RTX Spark and RTX Thunder lean a different direction, while the RTX Crush offers another distinct face within the range.
