The Alliance Flotmaster 381 is a radial flotation and steel belt tire that has been developed to meet the needs of specific niche applications on sensitive surfaces such as meadows, which require optimal soil and plant protection. The unique rib pattern, combined with rounded shoulders and sharper lugs, allows for maximum tire footprint and as low ground pressure as possible. The shoulder lugs, with excellent self-cleaning capabilities, allow for strong grip, thus preventing any skidding and any damage to the surface that could result from it.
