Tire structure

Tread, shoulder, sidewall, bead, carcass, belt, inner liner, and other components are structurally connected to complete the scientific structure of a tire.

Tread (the part that has direct contact with the road surface)

The tread consists of a thick layer of rubber which comes into direct contact with the road surface. It is highly resistant to fracture and shock in order to protect the carcass and belt located in the tire’s interior. Also, rubber with strong anti-inner abrasion features is used to increase the tire’s driving lifespan.

Shoulder (the shoulder of the tire)

Located between the tread and sidewall, the shoulder is the thickest part in a tire. Because of this, the shoulder is designed to quickly and easily dissipate heat that accumulates inside the tire while driving.

Sidewall (the side (lateral part) of the tire)

Located between the tire’s shoulder and bead, the sidewall protects the carcass on the inside and provides a comfortable riding experience due to its flexibility during driving. Also, the type of tire, size, structure, tread pattern, manufacturer, brand name, and other detailed information are marked on the sidewall.

Bead (the part that is in contact with the rim)

The bead wraps around the end of the cord and fixes the tire to the rim. It is made up of various parts including the bead wire, core, rubber and flipper. In general, the rim is slightly tightened so in the case of sudden reduction of air pressure while driving, the tire will not become unfastened from the rim.

Carcass (the framework of the tire)

The carcass is the framework of the tire, the most important part. The carcass refers to all layers made up of tire cord. It absorbs the tire’s internal air pressure, weight and shock.

Breaker or belt (the layer in between the tread and carcass)

The breaker is a cord layer placed in between the tread and carcass in a bias tire to protect the carcass. It absorbs external shock and prevents splintering or injury to the tread from coming into direct contact with the carcass. At the same time, the breaker prevents the separation of the rubber layer and carcass. The belt is a strong reinforcement layer located in the circumference in between the tread and carcass in radial tires. The belt’s functions are similar to those of the breaker but it also reinforces the strength of the tread by firmly tightening the carcass.

Inner liner

The inner liner substitutes for the tube in the tire’s interior and consists of rubber layer with low air permeability. The rubber layer generally consists of butyl, synthetic rubber, or polyisoprene type. The main function of the inner liner is to hold high-pressure air inside.

Tire pressure

The tire inflation pressure is directly related to safety. Therefore, tire pressure must be checked regularly, and proper maintenance can prolong the lifespan of the tires. Learn about the importance of tire inflation pressure and how to check the pressure of your tires.

Importance of tire pressure

- Optimum air pressure should be maintained to ensure safety, driving performance, tire life and fuel cost.
- Tires have been known to lose up to one psi in a month (psi: pound per square inch) Therefore, it is important to check all tires, even the spare, at least once a month or before a long trip.

Recommended interval

Tire pressure should be checked every month.

Checking for optimum tire pressure

Laufenn tire recommends you to check your tire pressure once in a month.
The optimum air pressure level for your tire can be found on the inner side of the car door (on the tire placard), inside the fuel cap or in the car manual (the location of the sticker can vary according to country).
DO NOT compare your inflation pressure to its maximum pressure marked on the tire’s sidewall.

How to check tire pressure

1. Purchase a certified air pressure gauge or take your vehicle to a nearby service centre for a check-up.
2. Tires must be checked in a “cold” state (at least three hours after driving).
3. Insert the gauge into the valve.
4. Compare the measured air pressure level with the level listed on the tire placard.

- If the measured figure is higher, release air until the figure matches what is listed on the tire placard.
- If the measured figure is lower, insert more air until the figure matches what is listed on the tire placard.
