A MICHELIN® X® TWEEL® airless radial tire is a single unit that replaces the current tire and wheel assembly. There is no need for complex mounting equipment and once they are bolted on, there is no air pressure to maintain The unique energy transfer within the poly-resin spokes helps reduce the “bounce” associated with pneumatic tires, while providing outstanding handling characteristics. They are designed to perform like pneumatic tires, without the inconvenience and downtime caused by flat tires. When it comes to reliability, Toro delivers replacement parts designed to the exact engineering specifications of our equipment. For peace of mind, insist on Toro genuine parts.
