Description
Is This for You?
- You're running a Ford F-150, Expedition, GM 1500, Toyota, Nissan, or 2019+ Ram 1500 on a 6x135 or 6x139.7 bolt pattern and want a 20x10 8-spoke wheel at -19mm offset in gloss black with machined spoke faces — the M28 GBM 6-lug is dual-drilled for 6x135 and 6x139.7, covering the two most common 6-lug half-ton and full-size SUV bolt patterns in a single SKU.
- You want machined spoke faces on the M28 platform — the GBM delivers fully machined spoke faces against the gloss black base. The GBML variant offers milled spoke accents if a different detail treatment is preferred. Same specs, different finish.
- You want moderate outboard stance on a lifted or leveled build — -19mm offset on a 20x10 wheel produces 4.75" backspace, pushing the wheel face outboard of the hub centerline for a wider stance without the clearance demands of deeper negative offsets.
The Result
- 20x10 at -19mm offset — moderate negative offset producing 4.75" backspace. Wheel face sits outboard of the hub centerline for a wider stance on lifted and leveled builds running 33–35" tires.
- Dual-drilled 6x135 and 6x139.7 — covers Ford F-150/Expedition/Navigator, GM Silverado/Sierra/Tahoe/Yukon/Suburban 1500, Toyota Tacoma/Tundra/4Runner, Nissan Frontier/Titan, and 2019–2026 Ram 1500 New Body (DT).
- 106.40mm hub bore — hub-centric fit for GM 1500 and Toyota platforms. Hub-centric rings required for F-150 (87mm), Ram 1500 DT (77.8mm), and Nissan platforms. Verify hub OD before installation.
The 106.40mm hub bore is hub-centric for GM Silverado/Sierra/Tahoe/Yukon/Suburban 1500 and Toyota Tundra/4Runner/Tacoma platforms. For Ford F-150 (87mm hub OD) and Ram 1500 DT (77.8mm hub OD), hub-centric rings are required. The -19mm offset places the mounting face 19mm inboard of the wheel centerline, producing 4.75" backspace. Brake caliper clearance must be verified before mounting tires. Lug nuts and TPMS sensors are sold separately. Once tires are mounted, wheels are non-returnable.

✘ Does NOT fit Ram 2500/3500 — Ram HD uses 8x165.1 or 8x200.
✘ Does NOT fit GM 2500HD/3500HD — GM HD uses 8x180.
✘ Does NOT fit any 5-lug or 8-lug platform — this is a 6-lug wheel. For 5x127/5x139.7 see M280528N19GBML.
Installation Notes
- Hub bore is 106.40mm. GM 1500 and Toyota platforms are hub-centric. F-150, Ram 1500 DT, and Nissan platforms require hub-centric rings — see hub bore reference table above.
- Verify brake caliper clearance before mounting tires. -19mm offset on a 10" wide wheel produces 4.75" backspace.
- Lug nuts not included. Verify lug seat type for your application.
- TPMS sensors sold separately.
- 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 height and tire size? Confirm your hub OD — this wheel is hub-centric for GM 1500 and Toyota (106.1mm) but requires rings for F-150 (87mm), Ram 1500 DT (77.8mm), and Nissan platforms. For 5x127 or 5x139.7 applications, see the M280528N19GBML instead.
