Michelin X Works XZY

Robust mixed-service tread. Michelin X Works XZY features a deep, symmetric block-and-rib tread engineered for mixed on/off-road duty cycles, with interlocking elements and rigid tie-bars to stabilise blocks under high torque and lateral scrub. This controls contact pressure gradients to mitigate heel-and-toe and river-wear on steer and trailer positions, while open shoulders improve self-cleaning on clay, spoil and aggregate so biting edges are restored quickly for dependable traction. An optimised pitch sequence helps manage pass-by noise on sealed roads, and the tread’s macro-block stiffness preserves braking stability. The outcome is confident grip from quarry access to motorway with slower, more even wear for a lower cost per kilometre.

Cut and chip-resistant compound. A specialised cut- and chip-resistant rubber compound pairs high-structure carbon black with advanced polymers to raise tear strength and reduce crack initiation under sharp aggregate loading common on New Zealand chipseal and construction sites. The compound’s elevated cut-growth resistance limits chunking and edge tearing in low-speed, high-slip manoeuvres, while a cool-running undertread manages hysteresis to protect the casing during sustained highway transits. Anti-oxidant and anti-ozonant packages mitigate environmental ageing and ozone checking, preserving elasticity at the groove base. Together, these chemistries deliver longer tread life and more predictable wear in harsh mixed-service environments.

Reinforced all-steel casing. An all-steel radial carcass with high-tensile cords, robust ply turn-ups and a heavy-duty belt package—including a full-width protector layer—provides superior crown stiffness and puncture resistance against impact and drilling from sharp stones. The bead area uses a reinforced apex and durable chafer to stabilise the lower sidewall, reducing flex-induced heat build-up and rim chafing during frequent load cycles and tight-site manoeuvring. This architecture maintains footprint shape across a broad pressure and load range, improving handling precision on-road and shock absorption off-road. Higher fatigue resistance translates into lower downtime and stronger eligibility for quality retreads, improving whole-of-life value.

Stone ejectors protect grooves. Integrated stone ejectors and stepped groove geometry actively purge retained stones from the circumferential channels, reducing crown penetrations and belt-edge stress that can lead to rust jacking and early casing loss. By preventing stone drilling, water evacuation capacity is maintained in wet conditions and localised heat from frictional drilling is minimised, preserving compound integrity. The groove base profile also resists packing with fines, improving self-cleaning on wet aggregate and clay. This design lowers the need for manual stone removal, protects the steel package and extends service life between yard visits.

Retread-ready Michelin casing. The Michelin X Works XZY casing is engineered for repeatable retreading outcomes, with controlled crown radius, consistent bead-seat geometry and a durable belt skim that promotes strong rubber-to-cord adhesion through subsequent curing cycles. Low casing growth and balanced crown stiffness help deliver an even buff platform for uniform tread application, while the reinforced bead and chafer system supports reliable remounting after retread. In practice, fleets can unlock multiple service lives (subject to inspection and operating conditions), reducing total cost per kilometre and environmental impact without compromising the tyre’s on/off-road performance envelope.
