Nomenclature for Passenger Car Tire

Update time : 2014-01-16 11:16:00

1.Tread: The tread is the part of a tire that contacts the road surface.
the tread consists of a layer of rubber compounded to suit the application purpose of the tire, and the thickness serves to protect the belt and carcass. Depending on the application a suitable tread pattern is molded at the time of curing. The tread pattern serves the purpose of improving water drainage, providing traction, braking, and cornering characteristics and aiding in NVH performance.
2.Shoulder The shoulder on each side of the tread is designed to protect the belt and carcass of the tire and to dissipate heat generated during running to the atmosphere.
3.Sidewall: The sidewall on each side of the tire, between the shoulder and the bead, is the section that deflects most during running. The rubber coating serves to protect the carcass.
4.Bead: The bead area supports the extremities of the carcass on each side of the tire. this is the part of the tire that anchors the tire to the wheel.
5.Belt: The belt is a reinforcement layer extending around the outer circumference of the carcass under the tread. It acts as an iron hoop in improving the stiffness of the tread area.
6.Carcass: The carcass is the load-bearing framework that forms the body of the tire. It is composed of rubber-coated fabric laid in a radial direction. The carcass contains the inflation pressure aiding in supporting the load and absorbing impact.
7.Inner liner: The inner liner is a layer of special rubber that has a high resistance to air migration.
8.Bead filler: This is a reinforcement rubber that has a triangular cross-section and which is used to increase the stiffness of the bead.
9.Bead wire: A ring-shaped reinforcement material that is made by bundling together several steel wires.
10.Chafer: A reinforcement cord for the prevention of cord layer broken.
