Its robust Michelin casing is built for durability and multiple retreads to lower total cost of ownership, while the tread design helps control irregular wear across New Zealand conditions. With dependable mileage and efficient rolling to help reduce fuel use, the XZH2 keeps fleets moving. Choose the Michelin XZH2 13R22.5 154G today for proven safety, longevity and value.

Heat-optimised tread compound. Through a functionalised polymer matrix with an optimised glass transition temperature and a carbon black/silica hybrid filler system, the Michelin XZH2 13R22.5 154G minimises hysteretic loss under cyclic deformation, reducing internal heat build-up in sustained highway service and high ambient conditions. Lower operating temperatures retard thermo-oxidative ageing of casing skim stocks and belt edge compounds, extending tread life and preserving retreadability. The compound’s abrasion and crack-growth resistance are balanced via controlled crosslink density, limiting river wear and micro-chunking on coarse New Zealand chip-seal. Reduced viscoelastic loss also lowers rolling resistance without compromising wet grip, supporting fuel-efficient operation over long duty cycles. This chemistry maintains consistent performance throughout the tyre’s service life, enhancing uptime and predictable removal mileage.

Reinforced all-steel casing. The XZH2’s all-steel radial carcass employs high-tensile steel cords in the body ply with twin steel belts at optimised angles and a robust bead package with high-stiffness apex fillers to deliver exceptional structural endurance. This architecture resists ply shear and radial growth at speed, stabilising the footprint and mitigating irregular wear modes such as shoulder step and river wear. A nylon cap ply controls belt-edge bending stress and centrifugal growth, improving heat resistance and enabling multiple retread cycles. Enhanced chafer reinforcement and bead design improve rim interface durability and air retention under high loads. The result is a cooler-running, retreadable casing engineered for high-load highway corridors and demanding intercity routes.

Optimised footprint geometry. A computer-optimised crown radius and rib/shoulder geometry deliver uniform ground pressure distribution, reducing strain concentrations that drive irregular wear on steer and all-position fitments. Stabilised tread ribs and shoulder decoupling features limit micro-slip at the contact patch edge, suppressing heat build-up during prolonged high-speed running and frequent roundabout manoeuvres. Even pressure reduces tread block squirm, keeping rolling resistance low while preserving consistent braking and lateral force generation in wet conditions. This controlled footprint preserves rib integrity over long mileages, supporting precise handling and extended removal intervals. It directly contributes to lower cost per kilometre through predictable wear-out.

Stone-ejecting groove design. Precision-engineered grooves with tapered stone ejectors and variable-pitch geometry prevent stone trapping and drilling, a primary cause of belt penetration on coarse surfaces common across New Zealand. By interrupting the helical retention path and reducing local pressure at groove floors, the design protects belt skim stocks from mechanical damage and limits corrosion initiation at steel cords. Cleaner grooves also maintain water evacuation efficiency, sustaining wet braking performance as the tyre wears. Protecting the steel package in this way maximises the probability of successful retreads and reduces unplanned downtime. Fleets benefit from longer casing life and lower lifecycle cost.

Fuel-efficient casing profile. The Michelin XZH2 13R22.5 154G employs a low-deflection contour with low-hysteresis sidewall and undertread compounds to reduce strain energy density per revolution, driving down rolling resistance without sacrificing durability. Carefully tuned carcass gauge and apex stiffness balance vertical compliance for ride with lateral stiffness for steering precision, limiting heat generation in continuous service. Lower rolling resistance translates to measurable fuel savings and reduced CO2 output at fleet level, while cooler running preserves belt edge adhesion and innerliner integrity for longer service life. Consistent performance over long heat-soak periods supports efficient utilisation across New Zealand’s varied highway topography. This efficiency-focused construction helps deliver a compelling total cost of ownership.
