Michelin Omnibib 620/70R42 160D

The Michelin OMNIBIB 620/70R42 160D is a premium radial tractor tyre engineered for mixed field and road work. Its wide footprint helps protect soil structure, while deep, self-cleaning lugs deliver strong traction and pulling power. A robust casing and reinforced shoulders enhance durability, and the optimised tread design provides a smooth, stable ride at transport speeds with lower rolling resistance to help save fuel. Long, even wear reduces cost per hour. Choose Michelin OMNIBIB 620/70R42 160D to lift productivity on Kiwi farms—ask for a quote today.

IF Ultraflex casing. The Michelin Omnibib 620/70R42 160D leverages IF (Increased Flexion) Ultraflex casing technology to carry up to 20% more load at the same inflation pressure, or the same load at up to 20% lower pressure versus a standard radial of the same size, elongating the contact patch to reduce peak ground contact pressure and shear. Flexible sidewalls manage deflection without concentrating stress at the bead, limiting hysteresis and heat build-up under cyclic field operations, so you can run lower pressures to protect soil structure, minimise rutting, and convert more engine torque into useful drawbar pull with lower slip and fuel consumption.

Optimised lug geometry. Deep, curved bars with tapered leading edges, generous inter-lug voids and a refined pitch sequence generate multi-angle biting edges for strong traction while promoting rapid self-cleaning in sticky soils. The Omnibib’s tread bars spread torque evenly across the footprint and are supported by a robust under-lug base, reducing localised shear and smearing; combined with a stable belt package, this improves longitudinal grip, trims slip percentage under heavy draft loads, and maintains consistent tractive efficiency across a wide range of soil moisture conditions.

Large, stable footprint. At IF-recommended pressures, the Michelin Omnibib 620/70R42 160D presents an enlarged, rectangular footprint with uniform pressure distribution from centre to shoulder, enhancing lateral stability on headlands and slopes and lowering rut depth in softer paddocks. The broader contact area spreads axle loads over more soil to decrease peak kPa under the lugs, helping preserve pore space and root zones, while the stable contact patch supports higher drawbar forces at lower slip, improving fuel efficiency and reducing time per hectare.

Road comfort and stability. Engineered for frequent road–field transitions, the Omnibib pairs a compliant radial casing with a stiff belt package and optimised tread pitch to damp vibration and reduce in-cab noise on sealed roads. Overlapping bar design creates a quasi-centre rib for precise on-centre tracking and shorter braking distances, while low-heat, low-hysteresis compounds and a reinforced bead zone maintain structural stability at transport speeds and under loader or towed loads, delivering predictable handling and even wear during regular road hauls between blocks.

Robust carcass durability. The Michelin Omnibib 620/70R42 160D features a reinforced carcass with strong bead bundles, durable tread compounds and protective buttresses at the lug base to resist fatigue, chipping and lug tearing under high torque and road abrasion. Thicker undertread and carefully engineered sidewall flex-control distribute strain to limit crack initiation during prolonged low-pressure use, while efficient heat dissipation reduces thermal ageing; the result is extended service life, fewer unplanned stoppages, and dependable performance in demanding mixed-use farming.
