9-57/64" Light-Medium Duty Ribbed Tread Solid Rubber Wheel, 550 lb. Load Rating

Flat-free solid rubber wheels can withstand heavier loads than pneumatic, semipneumatic, or flat-free polyurethane foam wheels, and they provide more shock absorption than semipneumatic wheels. They absorb shock and vibration for a cushioned ride and will not go flat if punctured, making them suitable for rolling over rough or uneven terrain in areas that may contain nails, metal shavings, rocks, or other sharp debris. The wheels have a hard rubber core and are heavier than pneumatic, semipneumatic, and flat-free polyurethane foam 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.
