Ultra Thick Urethane Wheels
(UT)
Ultra Thick Urethane wheels solve performance applications previously requiring press-on wheels. The thick tread reduces contact stresses in the polyurethane during high loading and towing which reduces tread chunking. These liquid cast wheels feature a chemical and mechanical lock between the core and the urethane. Each core has machined grooves to provide more surface area for good adhesion. These wheels provide you with: Softer Ride - good for towing applications; Quite Operation - due to tread thickness; Increased Bond Life - due to grooves in core and heat dissipation with thick poly. In addition, these wheels are non-marking to floors, provide outstanding abrasion resistance, and are resistant to most chemicals. |
