Michelin XZY 9.5R17.5 129L

Built for demanding mixed service, the Michelin XZY 9.5R17.5 129L is an all-position on/off-road truck tyre engineered to deliver safety, durability and productivity. A cut- and chip-resistant compound and deep, robust tread provide reliable traction on gravel and sealed roads, while a tough Michelin casing resists shock damage and supports multiple retreads to lower your cost per kilometre. Designed for even wear, stability and load capacity, the XZY helps keep your fleet moving with confidence. Available in popular sizes—enquire or order today.

All position mixed service. Engineered by Michelin for all-position fitment in mixed service, the Michelin XZY 9.5R17.5 129L delivers consistent steering precision on the steer axle, dependable drive/brake traction on powered axles, and stable tracking on trailers, enabling fleets to standardise one rugged pattern across construction, forestry, and rural delivery work. A balanced tread contour and optimised casing deflection maintain a stable footprint on New Zealand chip-seal and metal roads, reducing irregular wear in high-scrub manoeuvres and during frequent kerb contacts. The result is predictable handling on sealed highways with the durability and grip required off-highway, lowering cost per kilometre while simplifying inventory and rotation policies.

Deep non-directional tread. The XZY’s extra-deep, non-directional block pattern combines a robust net-to-void ratio with chamfered block edges to maximise mechanical keying on gravel, scoria, and clay while controlling heel-and-toe wear. Non-directional geometry allows flexible cross-rotation to even out torque and lateral scrub patterns, extending usable tread life. A reinforced under-tread and cooler-running base compound dissipate heat generated by carcass flex at highway speeds, supporting sustained load and distance without compromising mixed-service traction. For buyers, this translates into longer service intervals and dependable grip across seasons and surfaces.

Cut and chip resistance. Michelin formulates the XZY with a high-tear-strength, cut- and chip-resistant compound that blends premium natural rubber, optimised carbon black structure, and anti-oxidant/anti-ozonant packages to resist chunking and crack propagation on sharp aggregate and forestry debris. High molecular weight polymers and controlled cross-link density limit crack growth at the groove base, preserving block integrity under torsional loads. By reducing tread surface damage and the micro-tears that become stone traps, the compound protects the casing from penetrations, helping maintain air retention and extending casing life for retreadability—critical for controlling whole-of-life costs.

Reinforced all-steel casing. An all-steel, high-tensile casing with robust belt stabilisation provides exceptional crown rigidity and impact resistance, keeping the footprint flat under variable axle loads and reducing shoulder scrub. Michelin’s bead architecture uses a compact, multi-wire bead bundle with a hard apex and reinforced chafer to secure the tyre on the rim under high torque, braking, and low-pressure off-road conditions, reducing slip and bead fretting. Enhanced sidewall gauge and turn-up geometry help deflect impacts from rocks and potholes without transmitting damaging stress to the belt edges. The durable construction improves uptime and supports multiple retreads, driving down cents-per-kilometre in demanding NZ applications.

Self-cleaning shoulder grooves. Open shoulder channels with tapered groove walls and integrated stone-ejector features promote rapid evacuation of mud, slurry, and trapped stones, maintaining biting edges for traction while preventing stone drilling into the belt package. The groove architecture optimises pressure distribution at the rib edges to resist tearing in tight turns and during site work, while sipes and lateral notches maintain wet-road braking on chip-seal. By actively shedding debris, the design minimises heat build-up and belt-end stress associated with retained stones, supporting consistent performance between site and highway and reducing unplanned downtime.
