Maxxis MT772 Razr MT 33×12.50R18 122Q

Conquer NZ’s toughest tracks with the Maxxis MT772 Razr MT 33x12.50R18 122Q, a mud-terrain tyre engineered from off-road racing tech. Aggressive tread blocks and wraparound sidewall lugs bite hard in mud, rock and gravel, while stone and mud ejectors keep the footprint clear for consistent traction. A cut- and chip-resistant compound and 3-ply sidewall deliver serious puncture protection and durability, and the advanced tread pattern helps reduce on-road noise for a surprisingly civil ride. Built for utes and 4x4s that work and play, the Razr MT is ready to take you further.

Three-ply reinforced sidewall. The Maxxis MT772 Razr MT 33×12.50R18 122Q employs a robust three-ply polyester sidewall with high-tensile cords that disperses impact energy and resists bruise propagation, allowing you to air down with confidence for a larger, more compliant footprint off-road without sacrificing stability on-seal. Reinforced lower sidewall geometry and a firm bead apex reduce carcass deflection under towing or heavy ute loads, sharpening steering response and improving rim protection in rocky terrain, while the added lateral stiffness keeps the tread blocks properly supported to minimise squirm and heat build-up.

Aggressive sidewall biters. Large, scalloped shoulder lugs flow into functional sidewall biters to extend the traction zone beyond the tread face, generating additional lateral and longitudinal grip when the tyre is partially buried in ruts, sand, or mud. This wraparound armour helps claw for drive and side-hill purchase at reduced pressures, and also acts as a sacrificial shield against cuts and abrasions on rocks and logs, preserving the structural integrity of the Maxxis carcass for consistent performance over harsh Kiwi back-country tracks.

Stone and mud ejectors. Integrated ejector ribs and tapered groove geometry actively purge stones and packed clay from the voids, preventing stone drilling that can migrate through the belt package and cause punctures, as well as maintaining open channels for rapid self-cleaning in sticky mud. By limiting trapped debris that would otherwise amplify block movement and generate localised heat, the MT772 Razr MT sustains a stable contact patch and predictable traction on shingle, riverbeds, and metal roads, while reducing casing stress for longer service life.

Variable pitch tread blocks. A computer-optimised, multi-pitch block sequence with staggered central elements breaks up harmonic frequencies to reduce on-road pattern noise, improving cabin comfort without dulling off-road bite. Strategic block sizing and lateral tie-bars distribute stiffness across the footprint to curb heel-and-toe wear and micro-chipping on coarse chip seal, delivering more uniform wear, cleaner braking edges in the wet, and a confident steering feel that makes the Maxxis MT772 Razr MT 33×12.50R18 122Q easier to live with as a daily-driven mud tyre.

Cut-and-chip resistant compound. The MT772 Razr MT’s advanced off-road compound blends high-structure carbon black with abrasion-resistant polymers to deliver superior tear strength and micro-crack resistance, reducing lug chunking under high torque on rock and coarse aggregate. Optimised rebound and heat dissipation characteristics help control hysteresis at highway speeds, while maintaining elasticity across New Zealand’s temperature swings; the result is durable tread blocks that hold their shape, preserve sharp biting edges, and keep traction and wear rates consistent over thousands of kilometres.
