Michelin Xeobib

Ultraflex VF technology. Michelin Xeobib uses Very High Flexion (VF) casing technology to carry up to 40% more load at the same inflation pressure, or the same load at up to 40% lower pressure than standard radial tyres, enabling genuine low-pressure operation without sacrificing capacity. The highly compliant sidewall architecture and low-elongation cord materials allow greater vertical deflection, which expands and lengthens the contact patch, reducing mean and peak ground pressures (kPa) for measurably lower soil compaction and slippage. This improves tractive efficiency and fuel economy per hectare, stabilises drawbar pull in soft paddocks, and helps preserve soil structure for sustained yields, while the tyre runs cooler under mixed-duty cycles thanks to optimised carcass flex and compound hysteresis control.

Single pressure field to road. Engineered for stable operation at a constant, low inflation pressure across both paddock and transport duties, Michelin Xeobib minimises downtime from pressure adjustments while maintaining predictable handling on-road and high flotation in-field. The bead zone geometry, high turn-up casing construction, and optimised sidewall stiffness balance lateral stability at transport speed with the high deflection required off-road, controlling heat build-up and air retention at low bar settings. Contractors and farmers can standardise on a single working pressure within the published load/speed envelope, improving productivity, consistency of footprint, and tyre life by reducing thermal and mechanical stress from frequent pressure cycling.

Enlarged elongated footprint. With a long, wide, and uniformly loaded contact patch, Michelin Xeobib spreads axle loads over a greater soil area, lowering peak stresses at the lug tips and shoulders where compaction damage typically initiates. The footprint’s elongated shape reduces sinkage and shear at the tyre–soil interface, cutting rut depth and slip in wet conditions and reducing subsoil densification compared with conventional radials at higher pressures. The result is improved field efficiency, better fuel-to-hectare ratios, and enhanced agronomic outcomes, supported by consistent ground contact that stabilises machine attitude for precise implement control and accurate traction management.

Optimised traction lug geometry. Michelin Xeobib features curved, deep lugs with wide inter-lug voids and progressive tie-bars that maximise lateral and longitudinal grip while promoting rapid self-cleaning in sticky soils. The lug base is engineered to distribute stresses into the carcass, minimising tread squirm and heat, while the open shoulders evacuate mud to keep the biting edges engaged, reducing slip percentage under high drawbar loads. The result is higher usable tractive effort at lower engine revs, smoother power transfer, and reduced fuel burn, with uniform wear patterns that extend service life in mixed field–road cycles.

Reinforced bead and casing. The XeoBib’s bead package combines a robust bead filler, reinforced chafer, and optimised apex profile with a multi-ply radial carcass and high turn-up construction to maintain bead seating and sidewall stability at ultra-low pressures. This architecture resists rim roll and micro-movement under torque and lateral load, protecting against heat build-up and air loss in long transport runs while enabling the sidewall flex required for VF operation in-field. For operators, that means secure performance with heavy front loaders or rear-mounted implements, compatibility with modern CTIS/TPMS setups, reduced maintenance interventions, and confidence that the tyre will hold its profile and pressure across demanding New Zealand farming conditions.
