The flat-free, maintenance-free hand truck tire by Carefree Tire eliminates flats forever. It is made of micro-cellular polyurethane that makes the tire flat-proof without adding any significant weight to the tire. Constructed of thousands of microscopic air cells trapped in a matrix of incredibly tough polymer elastomer, the Carefree tire is amazingly lightweight, very durable, and significantly easier to roll than ordinary hard rubber tires.

This 10-inch diameter black hand truck tire features a sawtooth tread. It has a 3-inch centered hub and ball bearings for both a 5/8- or 3/4-inch axle.

The manufacturer tells me that Carefree tires will last at least four to ten times longer than pneumatic tires. Just think—no air, no leaks, and absolutely no flat tire downtime ever again!
