The RWM Signature premium wheel has a lightweight, reinforced nylon core with a high strength non-marking elastomeric rubber tread. The round tread provides easy rolling. Our durable nylon core is six times stronger than polypropylene. The performance rubber tread is cut, tear and corrosion resistant and will not chunk out. It has the highest strength-to-weight ratio than any other wheel in the industry. The Signature premium wheel is excellent for floor protection, continuous towing and noise reduction. The RWM Signature premium wheel is ideal for platform trucks, material handling carts, warehouse and factory applications, food service, drywall carts and assembly line dollies.
