In recent years, as people's awareness of automobiles has gradually increased, more and more attention has been paid to the safety and handling of automobiles. As an important part of a car, the performance of tyres directly affects the safety and handling of the car. You should know that all the weight of a car is carried by tyres; for all the sports characteristics of the car, the final performer is also the tyre. However, the contact area between the tyre and the ground is only equivalent to the size of a piece of A4 paper! Therefore, the importance of tyre is self-evident. Today, HUBEI AULICE TYRE CO., Ltd. will lead everyone to know the secrets of tyres.
The tyre crown, that is, the tyre tread, is the part of the tyre in contact with the road surface. Through friction, the car has driving and braking performance. It should have good wear resistance, puncture resistance, impact resistance, and heat dissipation. If the tread is aging and worn to a certain extent, it must be replaced in time, and the wear degree of the tyre crown has a special mark.
There is a triangle mark outside of the tyre. Follow the triangle mark, and you can see where the two arrows point is the wear mark. If the tread is worn to the level of the mark, it must be replaced in time.
It is the main force-bearing part of tires that is resistant to impact and should have good flexing resistance during driving. Ply consists of cotton, rayon, polyamide, steel wire, and other materials. Each cord thread should be isolated by ply compound to prevent cords from rubbing against each other, and the cords and layers should be tightly adhered to themselves, forming a flex-resistant and elastic whole part. The ply compound should have the properties of fatigue resistance, good adhesion, low heat generation, heat resistance, and aging resistance.
In our daily parking process, in many cases, because the distance is not well calculated, the off road dump truck tires will bump up against the curb, resulting in damage to the ply or causing the bulge. As the ply is the main force-bearing component in the tyre construction, once it is damaged or bulged, it must be replaced in time, otherwise, there will be a risk of tyre puncture.
The cap belt is a special ply layer above the belt layer, and when tyres are running, it restrains the movement of the belt layer, prevents the separation of the belt layer at high speed, and maintains the stability of the tyre running at high speed.

The tyre bead is made by a twining steel wire that is put on rubber material in a certain shape, which plays the role of fixing the tire on the rim, and it is composed of a bead core and chafer cloth. It can withstand the tension caused by the internal pressure, and at the same time, it can overcome the lateral force of the tyre during cornering so that the tyre will not fall out of the rim. Therefore, it must have strong intensity with tight and firm tyre construction and is not easily deformed.
