Rubber on iron wheels that American industry has grown to trust. By vulcanizing specially formulated rubber tread to iron centers we have created a truly rugged combination. Our top quality domestic rubber has nearly twice the military specifications for tensile strength. Its “springiness” allows improved rollability and some degree of debris rejection. Rubber tired wheels are known for excellent floor protection, very quiet operation and a cushioned ride even on rough floors. Standard tread is 70A hardness; also available in 90A extra hard, neoprene, and gray non-marking rubber.
