Michelin X Multi Z+ 9.5R17.5 129M

Built for regional and urban haul, the Michelin X MULTI Z+ 9.5R17.5 129M+ is an all-position truck tyre that delivers outstanding mileage, even wear and confident wet-weather braking. Its robust casing and damage-resistant tread are engineered for New Zealand’s varied roads, helping reduce downtime and keep your fleet moving. All-season traction (3PMSF/M+S on selected sizes) gives year-round confidence, while regrooveable, retreadable construction lowers your total cost per kilometre. Choose X Multi Z+ for dependable performance, safety and long-lasting value on steer or trailer axles.

Regenion Evolving Tread. Michelin’s self-regenerating groove architecture maintains a stable void ratio and fresh biting edges as the tyre wears, preserving wet grip and lateral control on regional chipseal and coarse asphalt. 3D interlocking sipes deliver block rigidity under load while opening under slip, minimising heel-and-toe wear on steer and all-position fitments. The evolving tread geometry sustains water evacuation rates over the tyre’s life, shortening wet stopping distances at higher residual tread depths. By stabilising local contact pressures, the design mitigates shoulder cupping in high-scrub metro work, extending legal-life mileage and reducing changeovers to lower cost per kilometre.

Infinicoil Crown Reinforcement. A continuous zero-degree steel belt, wound circumferentially across the crown, controls growth at speed and load to keep the contact patch geometry consistent under dynamic steering inputs. This reduces interply shear and belt-edge strain, lowering the risk of separations when repeatedly subjected to kerb strikes and roundabout scrubbing. The enhanced crown stability also improves lane-holding precision and wear uniformity on steer axles, especially on cambered rural routes. Cooler-running crown temperatures and reduced flex-fatigue translate to superior casing integrity, underpinning high retread acceptance rates and better lifecycle value.

Powercoil Low-Hysteresis Cables. Next-generation ultra-tensile steel cables in the casing deliver higher strength-to-weight with reduced hysteresis, cutting carcass heat build-up during long regional hauls and stop–start distribution. Lower operating temperatures reduce oxidation and cord fatigue at the ply turn-up, improving endurance under high-load, high-pressure service typical of NZ freight. The reduced energy loss per deformation cycle contributes to lower rolling resistance for improved fuel economy without sacrificing robustness. Enhanced cable compactness and adhesion promote consistent footprint pressure, suppressing irregular wear patterns that erode mileage.

Duracoil Bead Architecture. A reinforced bead zone with high-modulus protective rubber and textile wraps stabilises the rim–bead interface to prevent micro-movements that initiate fretting and chafer wear. This architecture spreads clamping forces more evenly around the bead bundle, reducing localised stress risers and heat in the turn-up area during heavy cornering and docking manoeuvres. Improved bead rigidity enhances steering response and limits shoulder scrub, while protecting against damage from repeated demounting. The result is a more robust, retreadable casing with fewer bead-related service removals, maximising uptime.

Cut-Resistant Multi-Compound. A cap–base tread package pairs a cut- and chip-resistant cap compound with a low-hysteresis base to resist chunking on aggressive chipseal while keeping crown temperatures in check. High-dispersion carbon black and silica blends, coupled with optimised polymer networks, deliver superior tear strength and abrasion resistance under torque and lateral scrub. Chamfered groove edges and stone ejectors mitigate stone drilling that can propagate to belt packages, preserving structural integrity. This chemistry–geometry synergy extends mileage in mixed regional duty while maintaining fuel efficiency and casing longevity for multiple retreads.
