MotoHammer Terrain Performance Guide

All-Terrain ▮▮▮▮▮▮▮▮▯▯ 8/10
A remarkably durable 8-ply radial that excels on firm surfaces. While it lacks the versatility to handle deep mud, its light-truck style construction makes it an invincible option for dry, rugged landscapes.

Mud ▮▮▮▯▯▯▯▯▯▯ 3/10
The extremely tight, interlocking tread blocks that make this tire so smooth on the street provide zero clean-out capability in the mud, causing the tire to quickly pack up and lose all forward traction in sloppy conditions.

Rock ▮▮▮▮▮▮▮▮▯▯ 8/10
The flat, wide footprint puts a massive amount of rubber in direct contact with the ground. While the compound isn't as sticky as a dedicated crawler, the high surface area provides highly reliable grip on dry boulders and slickrock.

Desert/Hardpack ▮▮▮▮▮▮▮▮▮▮ 10/10
This is where the MotoHammer dominates. Built with a rugged radial casing, it delivers a remarkably smooth, quiet, and vibration-free ride at high speeds on pavement, gravel, and hard-packed desert trails.

Mixed/Trails ▮▮▮▮▮▮▮▮▯▯ 8/10
An excellent choice for dry, rocky, or hard-dirt trail systems. The robust 8-ply construction provides elite puncture resistance against sharp roots and rocks, while the radial design absorbs trail fatigue.

Sand ▮▮▮▮▮▮▮▯▯▯ 7/10
Thanks to its wide, flat profile and closely grouped lugs, this tire offers surprisingly good flotation in light sand and desert washes, allowing you to ride on top of the surface rather than digging yourself into a hole.

Loose/Loam ▮▮▮▮▮▮▯▯▯▯ 6/10
Because the tread is optimized for rolling smoothly over hard surfaces, it lacks the deep, aggressive shoveling power needed to quickly bite through deep, loose loam or freshly tilled dirt.

Massive Contact Patch for High Predictability

Boasting one of the largest contact patches in the industry, the MotoHammer delivers "asphalt-like" traction on hardpack trails and desert floor. This wide footprint keeps your machine planted on uneven ground, virtually eliminating high-speed wobble and keeping your tracking laser-straight. By putting more rubber on the dirt through a dense, symmetrical center tread, the MotoHammer ensures your steering remains tight, crisp, and incredibly responsive.

Shoulder Tooth Lugs for Lateral Bite

Whether you’re hunting for a podium finish or just dominating the weekend run, the MotoHammer’s aggressive shoulder lugs are designed to maximize lateral traction. These sharp, "tooth-like" edges wrap down the sidewall to grab extra terrain as the tire flexes during hard cornering. This prevents the front end from washing out and allows you to power out of turns with total confidence.

Offset Lateral Channels for Improved Stability

By staggering the horizontal "valleys" between the tread blocks, these offset channels act as a natural defense against side-slip. Instead of providing a smooth path for the tire to slide sideways, the broken-up pattern creates multiple points of resistance that lock you into your line on off-camber hills. This ensures that when you’re side-hilling or navigating loose slopes, your momentum stays focused on moving forward rather than drifting off-track.

Additional Features and Benefits

  • Rugged 8-Ply Rated Carcass- Built for the harshest environments, the Motohammer’s 8-ply construction provides the structural "backbone" needed to resist punctures and sidewall tears. This heavy-duty carcass allows you to tackle rocky desert trails and debris-strewn trails with the peace of mind that your tires are as tough as your machine.

  • Advanced Nylon Radial Construction- By allowing the sidewall and tread to flex independently, this tire offers a significantly smoother ride and superior heat dissipation. The result is a tire that stays cool under pressure, tracks straighter, and delivers a much longer tread life than traditional bias-ply alternatives.

  • Championship-Proven Pedigree- The Motohammer isn't just "inspired" by racing, it’s forged in it. Torture-tested in the world's most grueling desert races, including King of the Hammers (KOTH), Best In The Desert (BITD), and SCORE International, this tire is engineered to thrive under the same conditions that break lesser equipment.

  • Surface-Hugging Soft Compound- The re-engineered rubber compound is designed to be compliant without sacrificing durability. This "active" rubber allows the tread blocks to slightly conform and "wrap" around terrain obstacles, providing a massive increase in grip on slick rock and technical climbs where harder tires would simply spin.

  • J/L/M-Rated for High-Speed Confidence- Don't let your equipment be the bottleneck on the fast stretches. All Motohammer tires come with a J, L, or M speed rating, certified for safe operation at high speeds. Whether you’re crossing a dry lake bed or pinned on a fire road, you can push the limits with total confidence.
