MAYHEM MONSTIR 8101 INNER BLACK

Mayhem MAYHEM MONSTIR 8101 INNER BLACK: a heavy-duty dually wheel

The Mayhem MAYHEM MONSTIR 8101 INNER BLACK is the inner-position half of a dually setup, built for heavy trucks and haulers that run dual rear wheels. This is a monoblock wheel with an aggressive, machined multi-spoke face carried in a blacked-out finish that keeps the inner wheel visually clean behind the outer. It sits in the Mayhem lineup alongside the other Monstir fitments and shares the brand's off-road, work-truck character.

Sizes and fitments stocked

This wheel is stocked in 19.5x6 and 20x8 diameters and widths, with the deep-negative offsets a dually inner position needs: -165 and -210. The 19.5x6 comes in a -165 bore configuration and a deeper -210 version, while the larger 20x8 runs a -165 offset with a 127mm bore. Because inner and outer wheels must be matched carefully on a dual-rear setup, run your numbers through the fitment calculator before ordering. Mayhem sizes for common truck patterns also live on the 8x165.1 and 8x180 pages.

Finish

As the name says, this is the inner black variant, a dark finish that disappears behind the outer wheel and looks purposeful on a work truck. If you want a different look for the visible outer wheels, Mayhem also offers chrome, gray and bronze options across the range.

Price and who it suits

Pricing runs from $544 to $583 per wheel. This one suits owners of dual-rear-wheel trucks who need a durable, correctly-offset inner wheel to pair with a matching outer. If you want a more conventional single-rear look, the Warrior and Chaos take different face designs, the Tank leans into a heavier spoke, the Assault and Rampage cover more standard truck offsets, and the Beast gives you a bolder split-spoke. Browse everything on the Mayhem brand page.
