Michelin Megaxbib 2 650/75R32 172A8

Ready your fleet with the Michelin MEGAXBIB 2 650/75R32 172A8, an agricultural tyre engineered for heavy harvest work. High load capacity at low pressures spreads weight for soil protection and flotation, while a self-cleaning lug design delivers confident traction in wet paddocks. A robust, stubble-resistant casing and reinforced shoulders maximise durability to cut downtime. On-road, the optimised profile improves stability and even wear for long service life. Ideal for high-horsepower tractors, harvesters and trailers. Choose Michelin quality to lift productivity, comfort and fuel efficiency.

Reinforced casing architecture. A high-strength radial carcass with multi-angle textile plies, a robust bead bundle and optimised apex/chafer geometry controls deflection under cyclic harvesting loads, dissipates heat through tuned rubber gauges, and distributes strain energy away from the sidewall/lug junction. This architecture enhances fatigue life and resistance to ply-end separation, limits rim slip at low field pressures, and maintains a stable, rectangular contact patch so the Michelin Megaxbib 2 650/75R32 172A8 carries heavy front axle and hopper loads with reduced heat build-up, improved retreadability, and fewer pressure adjustments across field-to-road transitions.

Wide, flat footprint. An optimised crown radius and enlarged section width generate a broad, even-pressure footprint that lowers peak ground contact stress, minimising subsoil compaction and rut initiation while improving flotation in wetter paddocks. The larger contact area reduces slip ratio at a given drawbar load, cuts shear stress at the soil–tyre interface, and stabilises longitudinal stiffness for smoother torque transfer. The result is more usable tractive effort per kilowatt, lower fuel burn, and slower, more uniform tread wear across centre and shoulder lugs in mixed field/road duty.

Optimised lug geometry. Deep, long-bar lugs with progressive taper, reinforced bases and wide, open inter-lug channels deliver high lug stiffness for torque transmission while promoting rapid self-cleaning to maintain traction as slip rises. A staggered, phase-shifted pitch sequence reduces harmonic excitation and tread squirm at transport speeds, and the lug base geometry spreads contact stresses to mitigate crack initiation. This geometry increases net-to-gross ratio in the contact zone for better dry grip, reduces rolling resistance on sealed roads, and preserves lug integrity under heavy braking and side loads on headlands.

Stubble-guarded tread compound. A cut-, chip- and puncture-resistant compound built on a high-structure carbon black system with advanced anti-oxidants/anti-ozonants and a tough under-tread reinforcement layer resists stubble spear penetration and gravel abrasion while controlling heat build-up from hysteresis. The compound’s elevated tear strength and crack growth resistance protect the lug leading edges and shoulders from chipping in maize and cereal residues, extending service life in aggressive residues and reducing downtime. Cooler running at sustained transport speeds further protects the casing and maintains inflation stability over long shifts.

Enhanced road stability. A stabilised crown package with tie-bar elements between central lugs, reinforced shoulders and a precise bead-to-rim interface improves on-centre feel, limits lateral deflection, and reduces vibration at transport speeds with heavy implements or full bins. The balanced mass distribution and low radial runout enhance ride quality, while controlled carcass flex lowers heat generation during long roading. This delivers confident handling, shorter settling time after steering inputs, and predictable braking on sealed and unsealed surfaces, helping operators move faster between blocks without compromising tyre longevity.
