Warrior WD266

Drive-Optimised Lug Pattern. Warrior engineers have configured the WD266 with interlocking central lugs, multi-angle sipes, and zigzag longitudinal channels to maximise mechanical keying on wet chip-seal and unsealed surfaces while stabilising the tread under high drive torque; the optimised net-to-gross ratio and shoulder tie-bars distribute shear stress evenly across the contact patch, reducing lug squirm, suppressing heel-and-toe wear, and delivering confident traction and braking on New Zealand roads across regional linehaul and metro stop-start cycles.

Cool-Running Cap/Base Compound. A dual-layer tread architecture pairs a silica-rich, silane-coupled cap for high wet µ at low temperatures with a low-hysteresis base compound that lowers tan d at 60°C, actively cutting heat build-up in the undertread and casing during sustained high-load operation; this reduces rolling resistance for better fuel economy, stabilises tread block modulus under thermal cycling to resist tear propagation, and helps keep carcass temperatures in a retread-friendly window to extend total tyre life.

Reinforced Retreadable Casing. The WD266 casing utilises high-tensile steel belts under a 0-degree nylon overlay with a turned-up body ply and a stiff bead apex to maintain footprint shape under torque and load, minimising belt edge strain and ply steer; enhanced chafer compounds resist rim chafing and heat, while balanced crown-to-shoulder stiffness prevents shoulder lift, enabling multiple quality retreads and lowering cost-per-kilometre for fleet operators who demand uptime and predictable wear patterns.

Stone Ejection Guard Grooves. Tapered groove walls and stepped groove bases integrate with dedicated stone ejectors to interrupt stone wedging and drilling, protecting belt integrity from impact and corrosion-induced fatigue common on coarse chip-seal and forestry access routes; by keeping grooves clear, the WD266 maintains designed water evacuation rates and contact pressure distribution, preserving wet grip and even wear deep into the tread life and reducing unplanned casing removals.

Even-Wear Shoulder Geometry. A computer-optimised cavity contour, variable-pitch tread sequencing, and shoulder tie-bars harmonise block stiffness to mitigate localised pressure peaks that cause river wear and heel-toe, particularly under repeated torque reversals on drive axles; this stabilised footprint lowers irregular wear noise, extends usable tread depth across the full width, and delivers consistent kilometre performance so the Warrior WD266 keeps vehicles productive between rotations and pulls.
