Optimised radial casing design. The Michelin Agribib 420/85R28 141A8’s radial carcass uses high-tensile textile plies and compliant sidewalls to distribute load uniformly across the tyre’s contact patch, reducing peak ground pressure while maintaining consistent lug engagement for strong tractive effort. Low hysteresis construction minimises heat build-up during field–road cycles, protecting the casing and stabilising inflation pressure. A precise ply turn-up with a stiffened bead area delivers confident handling and reduced shimmy at transport speeds. Operated at Michelin’s recommended pressures for the load, this design cuts slip, lowers fuel burn, and improves ride comfort, directly boosting productivity and lowering cost per hectare.

Deep, self-cleaning lugs. Agribib’s deep, open lug channels with tapered leading edges and optimised pitch spacing promote rapid mud ejection, preventing tread packing and preserving a high traction coefficient in wet clays and loams. The self-cleaning behaviour reduces slip ratio under heavy draft loads, limiting rut depth and safeguarding soil structure. Reinforced lug bases resist flex cracking under high torque, while the curved bar geometry provides progressive bite and smooth headland transitions, reducing driveline shock and enhancing implement control.

Reinforced bead and sidewall. High-strength bead bundles with robust chafer protection and a reinforced lower sidewall secure the tyre on the rim under high torque and lower operating pressures, reducing bead fretting and rim slip. Controlled sidewall deflection improves stability with front ballast or loader work and maintains steering precision on side-slopes. Added sidewall rubber gauges enhance cut and bruise resistance against stubble and field hazards, while the shoulder design mitigates heat concentration in mixed on-/off-road use, extending service life and reducing downtime.

Wear-resistant rubber compound. Michelin’s advanced tread compound in the Agribib balances abrasion, cut and chip resistance with low hysteresis to slow wear on chipseal and gravel without sacrificing off-road elasticity and grip. The formulation resists lug rounding and base erosion, maintaining effective edge length for sustained traction over the tyre’s life. Lower internal heat improves carcass integrity and helps maintain stable inflation, which translates to reduced rolling resistance, lower fuel consumption during transport, and predictable performance across long operating days.

Broad, stable footprint. Agribib’s crown profile and lug-to-void geometry generate a broad, flat footprint that spreads load to reduce ground pressure, protecting soil porosity and aiding root development and yields. A stable contact patch enhances lateral grip and braking with heavy implements, reducing hunting and wander on the road. Operating at Michelin’s recommended lower pressures for the load increases working contact area without excessive sidewall strain, improving traction efficiency, cutting fuel per hectare, and delivering consistent, repeatable performance across varied New Zealand paddock conditions.
