Maxxis AT771 Bravo AT 285/60R18 122S

Built for Kiwi adventures, the Maxxis AT771 Bravo AT 285/60R18 122S is a tough all-terrain tyre that delivers dependable traction on gravel and grass while staying quiet and comfortable on the highway. A cut- and chip-resistant compound and robust construction take on rough roads and towing, while staggered shoulder blocks and zig-zag siping bite in the wet. Wide grooves clear water and eject stones to reduce aquaplaning and drilling. Ideal for utes, SUVs and 4x4s, the AT771 Bravo AT offers long wear, control and value—ready to fit and go.

Interlocking Tread Block Design. Interlocking centre and shoulder blocks increase lateral and torsional stiffness under load, delivering precise steering on sealed roads while maintaining multi-angle biting edges for traction on gravel, wet grass, and light mud. By reducing block deformation and harmonising contact pressure, the Maxxis AT771 Bravo AT 285/60R18 122S minimises heat build-up and tread squirm during towing or heavy payloads, helping to curb irregular wear on New Zealand chipseal and improving braking stability across mixed surfaces.

High-Silica Rubber Compound. A silane-coupled, high-silica S-SBR/NR blend optimises the polymer–filler network to elevate wet-road friction (higher tan d at typical NZ winter temperatures) while lowering hysteresis losses at cruising speeds. This compound architecture enhances cut-and-chip resistance on coarse aggregate and farm tracks, resists chunking under sharp torque inputs, and stabilises tread temperature, translating to dependable wet grip, longer service life, and improved fuel efficiency without compromising off-road durability.

Variable Pitch Tread Sequencing. A multi-frequency pitch arrangement distributes impact and release events across the contact patch to disrupt tonal build-up, reducing cavity and pattern noise for quieter highway running. The varied block lengths and staggered shoulder edges smooth the excitation spectrum, lowering dB(A) in-cabin while maintaining dense sipe edges for wet bite. The result is a calm, composed ride on chipseal with consistent block engagement that preserves steering clarity and braking feel.

Reinforced Twin-Steel Belts. High-tensile twin steel belts, supported by a robust polyester casing and edge-reinforced belt package, stabilise the footprint at speed and under tow, improving longitudinal stiffness for confident braking and trailer control. Enhanced belt integrity resists impact shock from potholes and river stones, reduces the risk of belt-edge fatigue, and maintains uniform tread wear, giving the tyre reliable puncture resistance and predictable handling over long kilometres.

Self-Cleaning Stone Ejectors. Tapered groove bases and integrated ejector ribs purge stones before they seat and drill into the carcass, preserving casing integrity and mitigating air loss risks on shingle and forestry roads. By keeping the main channels clear, the pattern maintains water evacuation efficiency in heavy rain, prevents vibration from stone retention, and protects the tread from accelerated chip damage, ensuring consistent all-terrain traction and lower whole-life operating cost.
