Tire Construction

Tire, something you can’t imagine your car to move without. Tires are cushions to your vehicles. They are what soles are to the shoes. The air container is there to vehicle’s load. Tires have different section and each of them have their different significance. We will tell you what the purpose of each is:

1) Shoulder: The top corner end on each side of your tire’s tread is shoulder. Those were designed to protect the belt and the carcass of tire. Its purpose include disperse the heat that is generated while the tires are rolling.

2) Bead: Bead is meant to anchor the tire to the wheel. It stabilized the entire carcass. Some tires have lip protector on bead that keeps any scuffing of the lip onto the custom wheels.

3) Sidewall: This is primarily the display board that shows the information about the tire. It protects the carcass.

4) Tread: Tread of the tire makes contact with the driving surface. It is made of layer of rubber to suit the application purpose of the tire. The thickness serves to protect the belt and carcass. Its patterns improve water drainage, provide traction, braking and cornering characteristics and long tread life.

5) Carcass: This is the load bearing framework. It forms that tire’s body shape. The carcass is made out of a rubber coated fabric as well as steel cords that are placed in a radial direction.

6) Belt: It’s a reinforcement layer extending around the outer circumference of the carcass under the tread. It is design to improve the stiffness of the tire’s tread.

7) Blocks: It is build to provide traction.

8) Sipes: It is design to provide the traction by creating an additional biting edge. These are helpful on ice, light snow and loose dirt.

9) Ribs: The straight-lined row of blocks that create a circumferential contact “band”.

10) Void Ratio: The amount of open space in the tread. Low void means more rubber is in contact with the road. A high void ration increases the ability to drain water. The ratio depends on the intended use of the tire.

11) Dimples: Indentations in the tread the improve cooling.

12) Grooving: It assists channeling of water on wet road surfaces. It channels the water from in front to behind the tire.

13) Bead Filler: It is a reinforcement rubber that has a triangular cross section which is meant to increase the stiffness of the bead.

14) Bead Wire: A ring-shaped reinforcement material that is made by bundling together several steel wires.

15) Steel/Nylon Chafer: The chafer fabric and/more steel cords is wrapped around the bead section in order to reinforce it. It is conveniently composed of steel. Nylons are used sometimes depending on the specification.
