Structure of a TireModern tire technology blends a uniquemix of chemistry, physics and engineering to give consumers a high degree ofcomfort, performance, efficiency, reliability and safety. Many tires arecustom-designed to meet the stresses and performance needs specified by themaker of a particular model vehicle. Every tire is carefully inspected, andrandom samples are pulled for additional safety tests. As part of these tests,tires are x-rayed, cut apart and examined, run on test wheels, or road-testedto evaluate handling, mileage and traction performance. If properly cared for, tires can lasta long time - usually from 40,000 to 80,000 miles, depending on theapplication. TREAD: Provides traction and corneringgrip. BELTS: Stabilize and strengthen thetread SIDEWALL: Protects the side of thetire from road and curb damage BODY PLY: Gives the tire strength and flexibility BEAD: Assures and air-tight fit withthe wheel INNERLINER: Keeps air inside the tire |
