Fitment, Shipping & Product Support
Is This for You?
- You're running a Ford F-150, Expedition, Navigator, GM 1500, Toyota, Nissan, or 2019+ Ram 1500 on a 6x135 or 6x139.7 bolt pattern and want a 20x9 8-spoke wheel at +12mm offset in gloss black with CNC-milled spoke edges and lip accents — positive offset positions the wheel slightly inboard of flush, maximizing fender clearance on stock and leveled builds.
- You need a dual-drilled wheel that covers both 6x135 and 6x139.7 — the M08 GBML is drilled for both patterns in a single wheel, covering Ford, GM, Toyota, Nissan, and Ram platforms without ordering separate SKUs per bolt pattern.
- You want gloss black with milled detail at a 37 lb weight — the M08 GBML's CNC-milled spoke edges and lip accents deliver machined contrast against the gloss black base on a 1-piece alloy construction rated for daily driving, towing, and light off-road use.
The Result
- 20x9 at +12mm offset — positive offset positions the mounting face 12mm outboard of the wheel centerline, producing 5.47" backspace. Wheel sits slightly inboard of flush, reducing poke and maximizing fender clearance on stock and leveled builds.
- 106.40mm hub bore — hub-centric fit on compatible platforms. Verify your hub OD before installation; hub-centric rings may be required if your hub OD is smaller than 106.40mm.
- Dual-drilled 6x135 and 6x139.7 — single wheel fits both bolt patterns. Verify which pattern your vehicle uses before mounting; install on the correct set of lug holes for your bolt pattern.
The +12mm offset on a 20x9 wheel places the mounting face 12mm outboard of the wheel centerline, producing 5.47" backspace. This is a positive offset specification — the wheel face sits slightly inboard of the hub face, which reduces the outboard poke of the wheel relative to the fender and maximizes clearance between the inner barrel and suspension components. This makes the +12mm variant the correct choice for stock-height and leveled builds where fender clearance is a priority, while the 0mm variant (5.00" backspace) provides a more flush-to-outboard stance for builds where additional poke is desired. The dual-drill 6x135/6x139.7 configuration covers the two most common 6-lug half-ton and full-size SUV bolt patterns in the North American market. The 106.40mm hub bore is hub-centric for the listed applications. Lug nuts and TPMS sensors are sold separately. Once tires are mounted, wheels are non-returnable.

Installation Notes
- Verify brake caliper clearance before mounting tires. +12mm offset on a 9" wide wheel sits slightly inboard of flush — confirm inner barrel clearance against suspension components.
- Hub bore is 106.40mm. Verify your hub OD — hub-centric rings may be required if hub OD is smaller than 106.40mm.
- F-150 Raptor: verify hub bore compatibility for your specific trim before ordering.
- Lug nuts not included. Verify lug seat type (conical, ball, or mag) for your application.
- TPMS sensors sold separately. Verify sensor compatibility before installation.
- Once tires are mounted, wheels are non-returnable.
Engineering Question: What is your vehicle's year, make, and model, and what is your current lift or level height and tire size? Also confirm your hub bore OD and lug seat type. For Ram 1500, confirm 2019 or newer New Body (DT) — 2018 and older Classic Ram 1500 uses 5x127 (5-lug) and does not fit. If you want more outboard stance, see the 0mm offset variant.
