Warrior WS291 385/55R22.5 160K

Built for Kiwi roads, the Warrior WS291 385/55R22.5 160K is a no-nonsense tyre that delivers reliable grip, even wear and sharp value. Its tough casing and stable tread help it track true in wet and dry, soak up rough chipseal and keep road noise down, giving confident control and comfort on every trip. Choose Warrior WS291 385/55R22.5 160K for durability you can count on — dependable mileage, assured handling and fast fitment to keep you moving.

Five-rib straight tread. The Warrior WS291 385/55R22.5 160K uses a straight, five-rib pattern that stabilises the contact patch and equalises footprint pressure, reducing shoulder shear and mitigating heel-and-toe wear for longer tread life in steer and all-position fitments. Continuous ribs with optimised rib-to-groove stiffness improve on-centre tracking and braking linearity, while multi-pitch sequencing lowers harmonic noise. Longitudinal grooves are tuned for efficient water evacuation, maintaining micro-scale adhesion in wet conditions common on New Zealand roads without compromising tread block rigidity, which supports precise handling and uniform wear across regional and line-haul service.

Decoupling shoulder design. A dedicated decoupling groove at the shoulder of the WS291 isolates edge stresses from the primary ribs, allowing controlled lateral compliance that suppresses river wear and shoulder cupping on high-scrub routes. By interrupting crack propagation paths and acting as a thermal relief, the design reduces heat build-up at the belt edge—critical for casing durability under sustained loads—and provides an extra buffer against kerb scuffing in metro delivery work, extending usable life and preserving carcass integrity for retread.

High-strength steel casing. The WS291 casing employs high-tensile steel cords in a reinforced belt package with an optimised skim coat, coupled to a turned-up ply and robust bead apex for exceptional structural stability, air retention, and repairability. This architecture resists ply separation and belt-edge fatigue, distributing circumferential and lateral stresses evenly under varying loads, which enhances uniformity, eases balancing, and supports multiple retread cycles. The result is a lower cost-per-kilometre for fleets seeking dependable, retreadable Warrior casings across mixed NZ highway and regional networks.

Low rolling resistance compound. A low-hysteresis tread compound in the WS291, formulated with a balanced silica–carbon black system and advanced coupling agents, reduces energy loss (tan d) at operating temperatures to cut fuel consumption without sacrificing wet grip. A cap–base construction uses a cooler-running base to draw heat away from the belt edges, maintaining casing temperature within a protective window during long hauls. This chemistry minimises tread squirm and heat build-up on coarse chipseal, delivering tangible fuel savings and sustained performance metrics over the full tread life.

Stone ejector groove geometry. Engineered groove bottoms with tapered profiles and integrated stone-ejector features actively resist stone retention and drilling, protecting the WS291’s belt package from puncture initiation and corrosion. By promoting self-cleaning on aggregate and chipseal surfaces prevalent in New Zealand, the design maintains groove volume for water management and preserves rib stability over time. Reduced foreign-object intrusion directly supports casing longevity and retreadability, keeping vehicles in service longer and lowering unplanned downtime.
