KMC KM549 GRS 18x9 Wheel, 6x5.5 Bolt Pattern, -12 Offset, Satin Black

The KMC KM549 GRS wheel combines a rugged off-road design with a clean satin black finish for trucks and SUVs that need dependable performance and a distinctive appearance. This 18-inch wheel uses a 6x5.5-inch bolt pattern, also expressed as 6x139.7 mm, and features a -12 mm offset for an aggressive stance and added wheel clearance considerations.

Built with a 9-inch width, the KM549 GRS provides a strong foundation for a broad range of compatible tire sizes. Its 106.10 mm center bore supports proper hub fitment when matched to the vehicle application. The satin black finish delivers a low-gloss appearance that complements both stock and modified builds while helping the wheel maintain a purposeful, durable look.
