Maxxis HT780 Razr HT 285/60R18 116T

Built for everyday reliability and long-haul comfort, the Maxxis HT780 Razr HT 285/60R18 116T is the go-to highway tyre for SUVs and utes in NZ. Its continuous centre rib and multi-pitch tread deliver a quiet, stable ride, while a silica compound, full-depth sipes and four wide grooves boost wet grip and resist aquaplaning. A tough casing promotes even wear, durability and confident towing. If you’re after precise steering, low noise and serious mileage on Kiwi roads and motorways, step up to the Razr HT and get your set fitted today.

Variable pitch tread blocks. A staggered, multi-pitch block sequence across the five-rib pattern disrupts harmonic reinforcement and suppresses tonal peaks in the 200–1,000 Hz band, reducing cabin noise on chipseal and smooth asphalt alike. The Maxxis HT780 Razr HT 285/60R18 116T employs offset shoulder notches, tie-bars and chamfered leading edges to minimise air pumping and pipe resonance within the grooves, while maintaining block rigidity for precise steering. The result is a quieter highway ride without sacrificing tread block stability under braking loads, ideal for daily commuting or long-distance touring in SUVs and utes.

Silica-enriched tread compound. A high-dispersion silica compound, coupled with advanced silane coupling agents, enhances filler–polymer bonding to reduce hysteresis in the contact patch for lower rolling resistance and cooler running at motorway speeds. The compound’s optimised glass transition temperature improves wet traction by keeping the tread pliable in cooler New Zealand conditions, while fine 3D sipes generate micro-biting edges that sustain grip as the tyre wears. This chemistry delivers confident wet braking and cornering with extended tread life for cost-effective, all-season highway use.

Four circumferential water channels. Four wide, straight circumferential grooves with stepped walls and swept lateral notches accelerate water evacuation from the footprint, reducing hydrodynamic lift and improving contact stability in heavy rain. The groove geometry increases flow capacity and maintains an even pressure profile, while full-depth sipes act as micro-pumps to shear the water film at the road interface. This design helps the Maxxis HT780 Razr HT 285/60R18 116T maintain predictable steering and shorter wet stopping distances across variable NZ road surfaces, from smooth motorways to coarse chipseal.

Continuous centre stabilising rib. A solid centre rib with tightly spaced, interlocking sipes increases longitudinal stiffness to resist tread squirm, delivering crisp on-centre feel and linear response to small steering inputs. Under towing or heavy loads, the rib helps distribute forces evenly across the contact patch, improving straight-line tracking and braking stability. Combined with reinforced shoulder blocks, this architecture provides confident lane-keeping and reduced driver correction on long highway runs, enhancing both safety and driver comfort.

Jointless spiral cap ply. A jointless, spiral-wound nylon cap over dual high-tensile steel belts controls circumferential growth at speed, improving uniformity, reducing heat build-up and protecting belt edges against fatigue. The structure maintains a consistent footprint under dynamic loads and rougher chipseal, enhancing tread wear patterns and high-speed stability. Paired with a robust bead apex and hard bead filler, the Maxxis HT780 Razr HT 285/60R18 116T delivers durable carcass support for SUVs and utes, offering dependable performance for daily highway driving and weekend towing.
