12" Light-Duty Ribbed Tread Semi-Pneumatic Wheel, 185 lb. Load Rating

Semipneumatic wheels have a thick rubber wall with a nonpressurized air pocket in the center and will not go flat if they are punctured. They are suitable for rolling over smooth, flat surfaces in areas that may contain sharp debris. Semipneumatic wheels are lighter than flat-free wheels. They require less maintenance than pneumatic wheels because they do not have to have their air pressure checked. They are also more rigid and absorb less shock and vibration than pneumatic and flat-free wheels.

Pneumatic, semipneumatic, and flat-free wheels have air-filled, foam-filled, or solid-rubber tires that absorb more shock and vibration and produce less noise than standard wheels. These wheels are used on carts, trucks, dollies, and other equipment that will be transporting fragile or vibration-sensitive loads in laboratory, medical, or aerospace facilities. They are also installed on wheelbarrows and other equipment that will be used for moving loads over rough or uneven surfaces in outdoor areas and industrial facilities. The wheels allow the equipment to roll, which reduces the effort it takes to reposition or move the equipment.
