Q:Can I have two cars on the tyres?

[principles of tyre change]1. the same specifications, different specifications of the tire, its inflated outside diameter and cross-section width is not the same, mounted on the same axle, the load distribution is not the same.2. the structure of the same tread factor is different from that of the tread and skew, and its cushioning property and circumferential deformation are different. Two kinds of tire installed on the same shaft, the bearing load must not wear, are not the same.3. material same material mainly refers to the carcass cord material. For example, there are great differences of all steel radial tire and radial tire carcass thickness, fiber cord strength, thermal performance, mixed together effect.The 4. level is the same level of tire load level, at the same time to determine the pressure of the corresponding standards, the load capacity of different tire mixed together, the gas pressure is not uniform, the deformation of the tyre is also different.5. the same tire tread pattern is different, not only wear a difference, and the adhesion of the ground is not the same, the car around the tire tread is not consistent, will affect the vehicle ride comfort, emergency braking will be unilateral and tail phenomenon.6., the same brand, manufacturers are different, tire hub size, tread width, pattern shape, cord material are certain differences. Different brands of tires mixed together will affect the use effect.

Q:Is a military truck a bullet proof tyre?

Ordinary military cards don't need bullet proof tyres, only wheeled armored vehicles are bullet proof tyres, because bullet proof tires are expensive

Q:What minimum tread depth is required by law?

The national standard stipulates that the wear limit of radial tire tread for passenger cars is 1.6mm, and the wear limit of radial tire tread for trucks and coaches is 2.0mm.

Q:How many kilometers can a car tire run normally?

Ten thousand km gear wheel, not change, if it is symmetrical pattern, then left front wheel, right rear wheel, rn right front wheel, left rear wheel, so cross change. Another 5000 kilometers, it is best to give the tire a dynamic balance.

Q:Why are the tires black?

In 80s, the developed countries Japan, Germany and the United States have re production and put into the side of the tire with white font or ring tire, American Goodyear company even designed a fully transparent tire, it can be lit at night. In 90s, the French Michelin Co and a chemical group, substituted carbon dioxide, and achieved good results. Since the intrinsic color of silica is white, you can add any different staining agent, and you can choose any color from it. In recent years, with the emergence of new rubber anti-aging agent and white and light rubber reinforcing agent, the development of decorative tire is further promoted. Nevertheless, colored tyres are always used only as decorative tyres, and their cost, performance, and many other aspects are still not comparable to those of black tyres that have been used for decades.

Q:How often will the tires change? I've been using it for 3 years. Do I have to change it?

Need to change. The service life of a tire is usually 2-3 years or about 6-10 kilometers. Tread depth should be replaced immediately when 1.6mm (minimum wear). Tires that exceed the shelf life (especially the spare wheel and the spare wheel life of approximately 3 years) have fallen in overall performance.

Q:Truck selection of tires?

A long distance truck should be used so that all steel radial tyres can be used.

Q:What's the use of tyres, high pressure tyres and low pressure tyres?

Influence of tire pressure on vehicle safety:1., the tire pressure is too high or too low, will cause part of the tread is not grounded, thereby reducing the tire grip, affecting the safety performance of traffic2., over inflated tires will make their carcass too tight, tire fatigue. The shell is easy to break and cut3. the inflated tires will become excessive deformation and overheating, and eventually will lead to rupture of the shell. It has been pointed out that, due to insufficient air, the shell must bear most of the weight. Its potential risk is greater than that of over inflated tires.4. pressure can also affect the control of a vehicle, for example, to a degree of understeer or excessive steering.

Q:Does truck tire have inner tube?

Truck tires are basically divided into 3, one for the whole steel wire tire such as trucks, trucks, construction vehicles (such as tire inner tube, a need) is semi steel tire such as long-distance bus etc. (do not need such a class for inner tube), oblique tire such as bus, Dongfeng Cassidy (this kind of tire need the tube)

Q:How old is the truck tire screw?

The specifications of the tyres must be consistent with the specifications of the tyres assembled by the original vehicle. If you need to change the tire specifications, you must go to a professional refit shop to upgrade the tires or consult the car manufacturer.
