Can You Find Out What Exact Elements Constitute a Tyre?

 Product October 27, 2023


Tyres include several rubber compounds and other elements to function safely in various order to function safely in a variety of demanding settings.


Tyre bead bundles (often strands of wire) hold the tyre to the rim.

Filler for Beads

A silicone rubber applied above the bead bundle that can be utilized to tweak ride and handling qualities between the body flanges that curve around the bead.


Two belts with steel strands set at different inclinations are usual. Belts add stiffness to the tyre’s patch region, which improves wear, handling, and traction.

Ply Body

Most tyres feature one or two core plies, which are commonly made of polyester, rayon, or nylon strands encased in a rubber shell. Body pegs serve as the tyre’s backbone and give the rigidity required to maintain the hydrostatic pressure in check.


A rubber compound used to keep the tyre’s inflation pressure constant.


A rubber compound used to protect the body plies on the tyre’s sidewalls, providing abrasion, scuff and weathering resistance.


The tread elastomer composition and tread design give traction and high durability, which contribute to adhesion and treadwear.



Organic polymer gives tyres special efficiency qualities. It is very effective for rip and wears fracture toughness.


Butadiene latex and polystyrene butadiene rubber are the two most common synthetic rubber polymers used in tyre manufacture. These rubber polymers are blended with natural rubber. These rubber polymers’ both their chemical and physical qualities influence the performance of each component in the tyre as well as the total tyre efficiency(rolling resistance, wear and traction).

Halogenated polyisobutylene rubber (XIIR), often known as halo butyl rubber, is another major synthetic rubber. This substance makes the inner liner impervious, which aids in tyre inflation.


Steel wire is utilized in tyre belts and beads, as well as truck tyre planks. The belts beneath the tread reinforce the tyre casing, improving wear behavior and tyre handling. The bead wire anchors and secures the tyre to the rim.


Fabrics in tyres are several sorts of cloth threads that strengthen the tyre. tyre textile cords give structural accuracy and aid in unsprung weight support.

Polyester cord fabrics, rayon cord fabrics, nylon cord fabrics, and aramid cord fabrics are examples of these textiles. They are utilized in the manufacture of tyre plies in passenger tyres.


Antioxidants assist to prevent the rubber from degrading as a result of warmth and air contact.


Antiozonants are used to reduce the effects of acute exposure on the tyre’s area.


Sulfur and zinc oxide are essential elements in the transformation of rubber into a hard throughout the curing process or tyre curing. Curing techniques reduce vulcanization time and influence the duration and quantity of fibrils that develop in the polymer matrices during tyre curing or vulcanization.

Manufacturing Methods

Weaving of Beads

The bead is created using this procedure. The circle-shaped bead used in creating the bead component is formed by wrapping the rubber-coated bead wires around a device.


Rubber is applied to steel or cloth during the calendaring process, which is used to make tyres. The calendaring technique is used to create steel belts, body plies, cap plies, and belt edge coverings. It operates by squeezing two large rubber-coated wheels into the top and bottom of the material while pulling steel or cloth between them. Rubber is forced to penetrate and stick to the steel or cloth as it passes through the wheels by tension.


Tyre-building processes like extrusion are utilized to create thick rubber parts with specific shapes. Extruders are used in the production of treads, sidewalls, and bead fillers. The required form is created by pressing rubber into a compartment where it is heated and forced through a die.

Mixer inside

A massive, multi – story, covered device called the internal mixer is used to combine chemicals, rubber, and oil into every one of the polymeric material required to make tyres. The rubber is shaped into uniform thickness after being mixed under pressure so that it may be calendared and extruded.

Blue tyre

A mixture of elements that are chopped, extruded, and bead wrapped, then put together into a single sheet at a tyre organization to create.


The method through which pressure and heat are used to shape green tyres into the required dimensions and forms. The tyre’s tread pattern and sidewall lettering are molded into the tyre during the canning process, which also binds all the latex parts of the tyre altogether.


Tyres are composed of various materials, including rubber compounds, steel, and textiles, that are used to function safely in different environments. The tyre components include the beads, belts, ply body, innerliner, sidewall, and tread. tyres are manufactured through various methods such as weaving of beads, calendaring, extrusion, mixer inside, blue tyre, and curing. The manufacturing process involves combining different materials and curing them under pressure and heat to create a durable tyre that can withstand various conditions.


How can the components of a tyre be categorized and what do they consist of? 

Tyre components are classified into two primary structural parts, namely the tread and belt assembly and the casing, which are composed of multiple layers.

Can you provide information about the number of components in a typical tyre? 

Yes, a typical  tyre consists of approximately 25 components and can have up to 12 different rubber compounds.
