Maxxis M9060 Mud Trepador 38.5×12.50-16 128K

Built for the gnarliest bogs and rock-strewn tracks, the Maxxis M9060 Mud Trepador 38.5x12.50-16 128K is an extreme off-road tyre that delivers relentless traction and durability. Its directional, widely spaced lugs and stepped tread blocks bite hard and clear fast, keeping you moving through deep mud. A tough bias-ply carcass and reinforced sidewalls resist cuts and impacts, while aggressive shoulder lugs add side bite and protection. Confident at low pressures for maximum footprint and control. Order now and conquer NZ backcountry with Maxxis.

Deep Self-Cleaning Lugs. The Maxxis M9060 Mud Trepador 38.5×12.50-16 128K employs widely spaced, deep tread blocks with open shoulder channels that generate strong shear at the soil–rubber interface and evacuate viscous mud under centrifugal force, preventing clay packing and suction lock. The high void ratio improves flow pathways so slop and silt are expelled rapidly at wheel speed, keeping the leading edges sharp for consistent bite. This maintains a high tractive coefficient in cohesive soils and peat, reduces wheelspin-induced heat, and improves forward drive on steep, greasy climbs. The result is predictable traction you can count on when tracks turn to bogs.

Reinforced Bias-Ply Carcass. A competition-grade bias construction delivers exceptional impact resistance and sidewall stability, with cross-plied body cords that distribute loads uniformly to resist punctures and pinch cuts from roots and sharp rock. The carcass is tuned to operate at reduced pressures, allowing controlled footprint elongation without excessive sidewall growth, so the tyre conforms to terrain while keeping the bead seated under low-speed torque spikes. High-gauge sidewall rubber and a robust bead bundle provide rim protection and carcass durability under heavy vehicles and sustained winch loads. This translates to reliable mobility in remote, technical terrain where failure is not an option.

Aggressive Sidewall Biters. Prominent shoulder and sidewall lugs extend traction beyond the tread face, adding lateral grip when the tyre is partially buried or side-loaded in ruts. These biters interlock with rut walls and roots to create additional shear planes, improving the tyre’s ability to climb out of holes and hold lines on off-camber sections. The protruding blocks also act as sacrificial armour, dispersing impact energy and shielding the sidewall from cuts and abrasions. Expect superior rut negotiation and sidehill stability when you need to commit to a line and keep momentum.

Cut-and-Chip Resistant Compound. An off-road specific rubber blend with high tear strength polymers and reinforcing carbon black resists chunking and micro-tearing on sharp pumice and river rock, maintaining block integrity under diff-locked torque. The compound is engineered for low heat build-up, preserving modulus and edge stiffness during prolonged wheelspin in deep mud or winch-assisted crawls. Enhanced ozone and abrasion resistance protect against weathering and scoria-rich gravels common in New Zealand conditions, extending service life without compromising off-road grip. This durability keeps the M9060 Mud Trepador performing consistently across multiple tough trips.

Optimised Low-Pressure Footprint. Construction and buttress support are tuned to stabilise the tread blocks when aired down, enlarging the contact patch for superior surface conformity over roots, rocks, and ledges. Controlled block deflection maintains edge engagement while minimising lug squirm, so traction increases without excessive heat or tread tear under high torque. Bead and sidewall reinforcement work together to reduce unseating risk when traversing uneven cambers and when steering at very low pressures. The outcome is maximum mechanical keying into terrain for slow-speed crawling and mud progression with confidence.
