The Quaddro is equipped with two large drive wheels
featuring polyurethane tires. Rubber tires are
available as an option. The four load wheels are also
equipped with polyurethane tires of the same durometer
rating of 92 shore. Each pair of load wheels are
mounted to a load wheel assembly, and each pair of load
wheels are engineered to articulate, and thus designed to
provide some compensation for uneven floor conditions.
