KMC Mesa Forged Monoblock Wheel (KM446)
The KMC KM446 Mesa Forged is an upgrade on the KM544 Mesa, developed through extensive R&D. KMC used advanced metallurgy and forging to make it lightweight and ultra-durable. It is in our off-road wheels category.
It has a true forged monoblock build, a flat bead hump and a knurled bead seat. The knurling is meant to prevent de-beading and tire slippage at low PSI. A billet snap-in cap is included. Compare other non-beadlock wheels too.
Universal fitment, chosen by bolt pattern. Sizes: 17x8.5 -10mm, 17x8.5 0mm, 18x9 0mm, 18x9 18mm, 18x9 -12mm. Bolt patterns: 6x139.7, 6x135, 8x165.1, 8x170, 8x180. Finishes: Satin Black, Metallic Blue, Raw Machined. Check bolt pattern, offset and brake clearance against your vehicle before ordering.
