Tyre Structure


A considerable number of vehicles run on wheels. And tyres are attached to these wheels which is the point of contact between the car and the road. Just like any other things, the contact point is particularly crucial in the case of vehicles. Tyres have a fantastic way to work on the streets. They successfully balance the car on the road and make the drive smooth. Let us understand the whole mechanism and structure of a tyre.

Tyre Structure

These are not just rubber compounds. There is more to its structure. Tyres are made ring-shaped to fit the wheels and even though rubber is the main component of it, some other materials like carbon black, wire, etc. are also used to complete the structure.

  • Many might be aware of the different parts of car tyresThe inner liner of a tyre is a vital part as it is that hard layer made using airtight rubber which helps to maintain the firm structure of the tyre. This is a modern-day replacement of the old inner tubes used previously.
  • The sidewall of a tyre is another essential part, and most people know about it. This is the vertical area of a tyre side which comes in between the edge of the tread and tyre bead. This provides enough rigidity to the tyre and is responsible for absorbing all the shocks from the bumps. In this way, sidewall helps in smooth driving.
  • The tyre bead is at the tyre edge portion that sits on the wheel. This keeps the properly inflated tyre in the position attached to the wheel. So beading helps your tyres and wheels to stay connected.
  • Tyre treads are extremely important as they are the ones providing the grip and traction to the tyres on the road. This is the portion of the tyre which comes explicitly in contact with the road surface. The car handling and cornering ability is also dependent to a great extent on it.
  • Grooves within the tyre treads are also another vital part. It forms a single straight line in the tread which helps to maintain the stability of the car and also keep tyres in a straight line. Without this Tyres Coventry would have trouble in braking, and its direction might not be consecutive.
  • There is also a part in the car tyre which seems like a belt of steel wire. This one helps to keep the broadest part of the tyre tread to be in contact with the road surface.
  • The part that safeguards the steel wire from touching the rim of the wheel is known as the chafer. It is an inner tyre portion.
  • The carcass of a tyre is also a vital part of any tyre as it provides strength and support to the car tyres. It is like a mesh of wires or cords which evenly distributes the impact of all kinds on the tyres. The tyre weight is also appropriately balanced by this carcass. This portion of the tyre aids the tyre life since it helps it to sustain the constant rough use on-road. The continuous adjustment by flexing and compressions of a tyre due to the road impacts faced by it needs a material similar to the carcass to last for a more extended period and to deliver a smooth ride.
  • The tyre shoulder is the cause of even dissipation of heat which is continuously generated when the car is on the run because of the friction between a tyre and the surface. The area of a tyre right from the tread edge to the higher region of the sidewall is called the shoulder.

While these are some of the main essential parts of a tyre, there are a few more minor parts the knowledge of which can be skipped without much guilt. Tyre structure is a bit complex, indeed because of the various things it requires to do to make the car run safe and sound.
