If some tire marks like: 6 - 12, which indicates that it is not radial tire, but tire, the tire in the car now has been very rare, because of its safety, load capacity and high stability, and only used in some low-grade off-road vehicles and heavy trucks.

Q:What brand of truck tires wear?

Asymmetrical pattern: this kind of pattern is characterized by different tread patterns on the left and right sides of the tread. The lateral tread provides a high lateral support designed for cornering and handling, ensuring the handling of the turning of the dry ground. The inner tread ensures moisture and has better skid resistance when traveling. Asymmetrical patterns are super stable in telling travel and can bring extraordinary ride experience.Block pattern: block patterns are often used on off-road tyres, so they are also known as cross-country markings. The grooves of the patterns are also connected with each other to form an independent block structure. This pattern block is large, deep groove, which can improve the tire grip and traction. At the same time, the groove design is special, can let the tire automatic removal of stones and clods in the running process, performance contributes to the maintenance of the tire and prevent further loss.

Q:What's the difference between a steel tire and an ordinary one?

Ordinary tires, that is, crossed tyres. It's an old fashioned tyre. The tire is composed of tread, ply (carcass), buffer layer and bead, ply tyre is the skeleton, to keep the shape and size of the tire, usually made of multi-layer into even hanging tape (cord) with a rubber cord cord attached to, and tread the center line of approximately 35 angle, from one side of the bead through the tread to the other side of the bead. In the selection of nylon, polyester fiber or a high strength cord material, can greatly improve the tire load carrying capacity, improve the tire performance, is a commonly used modern automobile tires.

Q:The advantages and disadvantages of the gas in automobile tires

The tyre needs to be evacuated before charging nitrogen, and the original air in the tire is pumped out, but it is usually unable to pump the 100% vacuum. There is still a very small amount of oxygen remaining (1 - 2%). Furthermore, some vehicles (such as trucks, vans)... And other large vehicles, the tire to fill the pressure is higher, the corresponding tire oxygen rate needs to be reduced to 2 - 3%, in order to achieve the tire internal and external pressure balance. Based on the above situation, the conclusion is that the nitrogen purity of tire nitrogen is 95 - 98%.In the Bridgestone professional sales network "car wings", recommended to the user to use nitrogen tire.

Q:What are the steps to inflate the tires of a truck? What problems should I pay attention to?

When inflated, it should not exceed the standard, then deflate again. It can not be inflated too much because it can not be inflated for a long time. If more than the standard is too much, it will lead to excessive extension of the cord, causing its strength to reduce, affecting the tire life.

Q:How do you distinguish a steel tire from an ordinary one in a truck tire?

The middle part is diamond shaped, zigzag or pipe shaped. The two sides are horizontal cross-country, which is suitable for the road running between the city and the country.

Q:What does tyre 82H and 85V mean?

82: load index 475 kg, H: speed level 210kmh. 85: load index 515 kg, V: speed level 240kmh.

Q:How many kilometers are the tires guaranteed?
