Warrior WD506

Deep Lug Drive Pattern. Engineered for drive-axle duty, the Warrior WD506 uses deep, interlocking centre lugs with full-depth siping and stabilising tie-bars to maximise torque transfer and resist heel-and-toe wear. The high net-to-gross ratio across the contact patch delivers a larger, more uniform footprint, lowering contact stresses and minimising micro-slippage under high tractive loads. Chamfered leading edges cut shear peaks on entry while stepped lug bases control block deformation, reducing tread squirm and heat build-up for longer original tread life, consistent grip on wet chipseal, and dependable kilometres to removal in regional and mixed-service work.

Open Shoulder Channels. Wide, tapered shoulder grooves actively evacuate water, slurry and light mud, preserving edge bite on rural roads and construction approaches while keeping the footprint open for cooling air flow. The geometry promotes rapid self-cleaning, mitigating mud packing that can elevate localised slip angles and irregular wear. By lowering hydrodynamic pressure at the tyre–road interface and improving lateral drainage, the WD506 maintains traction stability in New Zealand’s variable weather without compromising shoulder integrity, supporting confident acceleration and braking on uneven, cambered surfaces.

Cut Resistant Tread Compound. A robust cut-and-chip resistant tread formulation blends high-structure carbon black with a cool-running polymer network to deliver abrasion resistance on coarse aggregate while keeping hysteresis and operating temperatures in check. The cap compound is tuned for tear energy control at the lug base, reducing crack initiation under high torque reversals, while a lower-hysteresis base underlay draws heat away from the belt edges. This compound strategy helps the WD506 withstand scoria, metal and forestry tracks common in mixed service, extending tread life and protecting the casing for subsequent retreads.

Stone Ejector Ridges. Strategically placed stone ejector ribs in the main circumferential grooves disrupt stone wedging and prevent drilling into the belt package. By manipulating groove floor pressure gradients and using stepped groove walls, the design forces debris out as the footprint exits, reducing penetrations that can propagate rust and belt-edge separations. This safeguards the steel cord integrity, maintains uniform stress distribution across the crown, and improves air retention over time, translating to less downtime and improved retreadability for cost-per-kilometre control.

Heavy Duty Retreadable Casing. The WD506 features a high-tensile all-steel radial casing with a reinforced bead apex, robust chafer and stabilised belt package capped with nylon for footprint uniformity at highway speeds. The carcass architecture is optimised to balance vertical compliance with lateral stiffness, controlling shoulder deflection under torque while keeping crown temperatures within the ideal window for carcass longevity. Enhanced innerliner airtightness and turn-up geometry protect ply endings against fretting, supporting multiple quality retreads and delivering maximum lifecycle value for fleets focused on total cost of ownership.
