Because changing a tire often requires more than one tire iron, this set includes two 12" Tire Irons. 12 inch size provides excellent leverage for those tough to change tires with rounded edges help avoid tube pinching and tire damage. One end is flat 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.
