Because changing a tire often requires more than one tire iron, this kit include one 16" Tire Iron and two 8-1/2" Tire Irons. The 16" size provides excellent leverage for those tough to change tires and the 8-1/2" are perfect for holding the bead in place. Both sizes feature one flat end for holding and prying with the other curved for a better grip on the bead. I-Beam cross section increases strength and bend resistance without added weight. Made from high quality drop forged steel then heat treated for strength and durability.
