The STARCO Alptrak tire is engineered to excel where ground is soft, uneven or sloped — delivering reliable traction and stability even in demanding turf or soil conditions. Its unique tread pattern is specifically designed to provide maximum grip on turf and soft terrain, ensuring lateral traction and control for work on steep slopes or soft ground.

Thanks to the tread design and overall construction, Alptrak performs well when you need strong traction for compact tractors or turf‑tractors, while still being gentle enough to preserve soil structure and turf integrity — critical for ground‑care, landscaping, or agricultural utility use. Its design balances traction and soil protection, making it suitable for varied terrain from soft soil and turf to wet grass, hills ,sand and snow conditions.
