Off Road Monster M12: Aggressive Monoblock Truck Wheel

The Off Road Monster M12 is a monoblock wheel built for lifted trucks and off-road rigs that want a deep concave face and serious width. This is one of the more aggressive faces in the Off Road Monster lineup, with a rugged split-spoke look that fills out big wheel wells and stands up to trail duty.

Sizes and fitments in stock

The M12 runs in 20-inch and 24-inch diameters, in widths of 9, 12 and 14 inches. Offsets cover a wide aggressive range, from 0 down to -44 and a deep -76mm for maximum lip and poke.

Bolt patterns stocked include 5x127, 5x139.7, 6x135, 6x139.7 and 8x165.1, plus blank options you can drill to spec. For a mild street-truck stance, the 20x9 in 6x135/6x139.7 Gloss Black works on half-ton trucks, while the 20x12 -44 in 8x165.1/8x170 clears the heavy-duty crowd. Going big and deep, the 24x14 -76 in 6x139.7 Gloss Black Milled pushes the lip hard. There's also a 20x9 blank in Gloss Black Milled for custom drilling.

Finishes

Choose from Gloss Black, Gloss Black Milled, Gloss Black Machined, Flat Black, Flat Black Milled and Chrome. See more dark-finish options on the black Off Road Monster page.

Price and who it suits

The M12 runs from $249 to $651 per wheel depending on size and finish, so a set of 20x9s stays budget-friendly while the 24x14 deep-lip builds sit at the top end. It suits lifted trucks and off-road builds that want an aggressive, wide, concave stance without going to a multi-piece wheel.

If you want a different face on the same rig, the M10 and M14 share the aggressive truck brief with alternate spoke designs, the M22 and M26 offer different mesh and spoke looks, and the M08 gives you another split-spoke option to compare. Browse the full new wheels catalog for more.
