A Brief Introduction To Tire Components

The tire is the main part of the vehicle that also comes in contact with the road. Tires must strike a balance between grip, comfort, strength, and cost. Because of these needs, tires are more unpredictable to manufacture and need more work than you realize. As it has a complex manufacturing process it is always beneficial to know the manufacturing process and the parts consisting of a tire. We at, Sailun Tires, a leading cheap tire shop in the Philippines, understand the importance of such knowledge before you buy a tire. In this blog, we are giving a brief introduction to the tire components.

Inner Liner

An airtight layer of synthetic rubber which is the modern equivalent of an inner tube. The inner liner assures that the tire will hold high-pressure air inside, minimizing diffusion through the rubber structure.

Body Ply

Also known as Carcass ply it is the layer above the inner liner. It consists of one layer of rubber, one layer of reinforcing fabric, and the second layer of rubber. Body plies give the tire structure strength. Truck tires, off-road tires, and aircraft tires have progressively more plies. The fabric cords are highly flexible but a bit inelastic.

Sidewall

It protects the side of the tire from impact with curbs and the road. Important details about the tire are written on the sidewall, such as tire size and speed rating. Sidewalls are non-reinforced extruded profiles with additives to give the sides of the tire good abrasion resistance and environmental resistance.

Beads

They clamp firmly against the tire’s rim to ensure an airtight fit and keep the tire properly seated on the rim. Bead wire is coated with special alloys of bronze or brass. Coatings protect the steel from corrosion. Bead rubber includes supplements to maximize the strength and toughness of tires.

Apex

The apex is a triangular extruded profile that mates against the bead. The apex provides a cushion between the rigid bead and the flexible inner liner and body ply assembly.

Belt Package

Belts consist of a layer of rubber, a layer of closely spaced steel cords, and the second layer of rubber. Belts give the tire strength and dent resistance while allowing it to remain flexible. It also reduces friction heating and helps maintain the shape of the tire when driving fast.

Tread

Tread is the most important part of the tire. It provides traction and grip while driving and is designed to resist wear, abrasion, and heat. Tread compound development is a bit difficult, as hard compounds have long wear characteristics but poor traction whereas soft compounds have good traction but poor wear characteristics.

Cushion Gum

Many higher-performing tires include an extruded component between the belt package and the tread to isolate the tread from mechanical wear from the steel belts.

These are the 8 parts that consist of a tire. In the next blog, we will give you a brief introduction on the manufacturing process of a tire.
