This preview shows how RTX Slate 6x139.7 20x9 +20 Satin Black wheels look on a 2024 GMC sierra. Use this page to compare finish, diameter, and overall styling before buying.
The 20×9 RTX Slate with a +20 offset sits in the moderate-to-aggressive range for a full-size truck platform; this depth and offset combination typically delivers a near-flush appearance at stock ride height on most Sierra trims, though fender clearance depends on your specific suspension setup and whether you plan to lower the vehicle. A square tire setup (matching widths front and rear) is common for truck aesthetics and provides balanced wear; consider 275–285 mm width to match the wheel's proportions without excessive stretch. Verify bolt-pattern compatibility (6×139.7) with your model year before purchase.
