Corona Max Flat Free Tire Knobby-16 in

Flat-free micro-cellular polyurethane foam consists of trillions of air cells. The polyurethane foam is self-skinning foam which creates a tough outer skin that is two times stronger than rubber. Includes ball bearings for years of smooth performance and grease fittings for easy lubricating. Knobby tires provide added traction and longer wear. The non-marking skin is abrasion and chemical resistant. For use on selected Corona Wheelbarrows including WB 2506K, WB 2606K, WB 2706, WB 2006, WB 1006
