Tire Guards... protect tread face of tire from nails, glass, thorns, staples and other sharp objects
If flats are giving you headaches and too many tire repair bills, then use our one-piece tire guards which are made of a very durable, high density rubber that will stop all sorts of sharp objects. They virtually never wear out and are a fraction of the cost of foam-filled tires, yet are ideal for mowing operations, street sweepers, scrap yards and waste haulers. Pressure of tube holds tire guard in place. Use a new tube when installing these guards. Note: Tire guards are not for highway use.
Tire Size: 18.4 x 30.
