Bias tyre is intercrossed by multilayer treads. Due to different materials, it can be divided into cotton tyre, rayon tyre, nylon tyre, polyester tyre and steel wire. Here are their features: 1. Cotton tyre. Cotton tread is made by cotton textile. Cotton is the earliest material used in tyre making. Due to its low intensity, multiple layers, high heating, slow heat transfer, few re-treading time and much water absorption, it has no longer been used. Even so, other materials still take cotton as standard, which has become a practice in tyre industry till now. 2. Rayon tyre. After cotton, rayon has been widely used, which firstly appeared on Paris Exhibition in 1889. Invented by a famous French physiologist, it has the same luster and feeling like silk but is more highly tensile than cotton. By its features like heat and fatigue resistance, it became main material of tyre making. Compared with the cotton tyre, rayon tyre is better in comprehensive performance, which made tyre industry stride forward again. Its disadvantage is hygroscopic so as that its strength will be reduced in wet condition. 3. Nylon tyre. Nylon was invented by an American chemist and published by his Dupont Corp. in 1938. Since publication, it has caused widely attention in the world. Some guys called it “Tougher than steel, thinner than spider silk, made by coal, air and water, but elastic and shining like protein fibre”. As tyre tread, nylon is more tensile, impact resistant, elastic, lower density, renewed and difficultly hydrophilic, but its disadvantages are thermal expanded and easily deformed. In winter, if vehicles parked outside for a long time, there will appear “flat spot”, which is caused by this, too.

Good driving habits and vehicle tyres will help to ensure good use of state, here to give you some tips to extend the service life of the tyre:

1, not speeding. Speed ​​too high will increase the tyre flex, resulting in excessive heat and accelerate tyre wear and shorten life.

2, in the car to run them, should try to avoid hard acceleration, emergency braking and sharp turn, not only the mechanical properties of the car itself is bad for tyre life and disadvantages. If repeated hard acceleration, emergency braking and emergency steering is not normal driving, can cause rapid tyre deformation, uneven tread wear, tear longitudinal grooves, the tyre internal temperature rises, easy to puncture.

3, following the maximum load, do not overload. Tyre life depends largely on the size of the load, frequent overloading of the tyre life 20% will be reduced to 50% of the normal life span. Overload also makes the tyre temperature, pressure increase, increased fatigue of rubber and cord, likely to cause delamination.

4, on the road to avoid potholes or obstructions.

5, to avoid hitting the road Yashi, Yashi Parking Do not get on the road.
