Flotmaster 381

Alliance Flotmaster 381 is a radial flotation tire that has been developed to serve the needs of specific niche applications on sensitive surfaces like grasslands, which require optimized soil and plant protection. The unique rib-type pattern, together with rounded shoulders and more aggressive lugs, enables the maximum possible tire footprint and the lowest possible ground pressure. The shoulder lugs, with excellent self-cleaning capabilities, enable strong grip, thus preventing any excessive tire slippage and any consequent damage to the surface. The Flotmaster 381 is available in a range of sizes and construction options to choose from.
