Maxxis MT764 Bighorn MT 225/75R16 115Q

Conquer NZ terrain with the Maxxis MT764 Bighorn MT 225/75R16 115Q, a tough mud-terrain tyre built for serious 4x4 and ute duty. Its aggressive, high-void tread and staggered shoulder blocks deliver powerful bite in mud, ruts and rock, while self-cleaning channels and stone ejectors maintain traction. A robust carcass and reinforced sidewalls help resist cuts and punctures; bold sidewall lugs add extra grip and protection. On-road, the MT764 stays stable for a mud tyre. Choose the Bighorn MT for dependable off-road traction, durability and value—ready to fit. Order your set today.

Aggressive self-cleaning lugs. The Maxxis MT764 Bighorn MT 225/75R16 115Q employs a high void ratio with deep, tapered lateral and longitudinal channels that generate strong centrifugal expulsion and pressure differentials to shed viscous clay and slurry, preventing lug packing. The staggered, scalloped blocks present multiple leading edges that maximise shear force transfer in mud, while chamfered trailing edges reduce suction lock so the tyre releases substrate cleanly. The result is consistent bite and forward traction in deep ruts and sticky NZ clay, along with stable braking as the contact patch stays open and free of debris.

3-ply sidewall protection. A tri-ply polyester carcass with reinforced ply turn-ups and aggressive sidewall lugs increases sidewall gauge and impact energy absorption, improving resistance to stake strikes, rock ledges, and pinching at low pressures. The stiffer sidewall cords enhance lateral stability under load, while the bead apex and rim guard geometry support the lower sidewall to minimise deflection and protect against bead unseating when aired down for sand or rock. This construction delivers confident control for utes and 4x4s on rugged tracks without sacrificing casing durability.

Cut-and-chip resistant compound. Maxxis engineers specify a high-tear, cut- and chip-resistant tread formulation using a robust carbon black reinforcement system and optimised crosslink density to resist chunking on sharp scoria, river rock, and coarse NZ chipseal. The compound balances hysteresis for off-road grip with controlled heat build-up at highway speeds, reducing crack initiation at the lug base and preserving block integrity. This chemistry translates to longer usable tread life, sustained traction edges, and lower risk of belt package damage from stone drilling over the tyre’s service life.

Steel belts with nylon. Twin high-tensile steel belts topped by a spiral-wound nylon cap stabilise the tread at speed, limiting circumferential growth and lug squirm for precise steering and predictable on-road braking. The architecture maintains a uniform contact patch across variable loads and camber, reducing heel-toe wear on the large blocks and promoting even wear patterns. For towing or long highway runs between off-road sites, this belt package enhances straight-line stability and ride confidence while protecting the carcass from impact deformation.

Stone ejector technology. Raised, wedge-shaped ejector ribs seated in the primary grooves disrupt stone retention and prevent drilling, reducing stress risers in the tread base and safeguarding the steel belt skim from puncture pathways. By continuously clearing gravel and shingle picked up on forestry or farm roads, the design preserves groove volume for water and mud evacuation and helps maintain dynamic balance by avoiding mass build-up in the tread. The outcome is fewer puncture-related downtime events and more consistent performance across mixed terrain.
