Engineered for the toughest job site conditions, the Carlstar Ground Force® 400 Ultra is built to deliver exceptional durability, extended service life, and reliable performance in severe-duty applications. Designed specifically for skid steer loaders operating in harsh environments, this tire is the ideal solution for contractors who demand maximum uptime and long-term value.

The Ground Force® 400 Ultra features an aggressive, heavy-duty tread design with a tread depth that is 70% deeper than standard premium skid steer tires, providing enhanced traction and significantly improved wear resistance.
