Truck and Bus radial tyre pattern 389

Q: Army trucks are big and heavy tires. Are regular trucks fast or military trucks fast?: Military trucks have off-road requirements, in addition to ordinary roads, not paved dirt roads, and even wasteland, fields should be able to pass, so the tires wide, big pattern, resistance is large, slow

Q: How often will the pickup tires be replaced?: But to remind you that the tire is valid for 5 years after the factory, because rubber has aging period, therefore, regardless of whether the mileage reached 100 thousand kilometers, 5 years after the factory deadline, it is best to change.

Q: How long will it take to fill the truck tires?: The tire with inner tube is good enough to connect the air gun to the valve. But if there is no inner tube, consider the problem of side leakage. It's more troublesome to operate. Inflation pump pressure is generally 8-9kgf, there are high-pressure compressor.

Q: How are the tires classified?: From the design perspective, bias tyre has many limitations, such as cord cross strong friction, easy to make the matrix heat, so the accelerated wear tread, and the curtain line layout is not good enough to provide excellent handling and comfort; and irregular steel ribbon in radial tire it has good flexibility to adapt to the impact of the road, and durable, it also means that the fabric structure is much smaller than the oblique line friction in the car, which has long service life and better tread fuel economy. At the same time, the radial tire itself makes it possible for the tyre to have no inner tube. Tubeless tire has a recognized advantages, namely when the tire is punctured, unlike a tubeless bias tyre burst (as this is very dangerous), but to make the tire can maintain pressure within a period of time, improve the safety of driving a car. In addition, the radial tire has better grip ability than the inclined line tire. Because the radial tire has the above advantages compared with the inclined line tire, it is now widely used in the car radial tire.

Q: Is the tire good or small?: Tire, better grasp, open up more stable and more secure, whether it is wet and slippery pavement or potholes will be safer, but the relatively large tires, will be more fuel,

Q: How many layers of steel tires are there in a big truck?: PR is the meaning of hierarchy, which refers to the nominal number of plies in the tire rubber layer, which is not consistent with the actual ply number. It is an important indicator of the tire strength. Levels are marked in Chinese, such as 12 levels. In English, such as "14P.R", that is, the "14 poles".

Q: When does the car tire?: Please check regularly for all tire pressure during cooling (at least once a month), including the spare tire. The correct inflation rate of the tire under cooling conditions shall be based on the parameters recommended by the vehicle manufacturer. If the pressure decreases too quickly, please find out the cause (for example: nail sticking, cutting, rubber aging, cracking, etc.).?The definition of tyre cooling: at least three hours after parking, or no more than 2 km of tire travel. If you can only measure the tire pressure during the hot tire, please subtract the measured tire pressure value by about 0.3 bar (=4psi), that is, the tire cooling and charging pressure.

Q: Auto tires 102H what do you mean?: Tire 102H: the maximum speed of the car at 102 load is 190km/hThe meaning of H and T:H/T is the speed levelThe maximum speed at which the H is under the load of the tire is 210km/hThe maximum speed at which the T is under the load of the tire is 190km/h

Q: How often do the tires change?: If there is partial wear, eating tires, should be done as early as four wheel positioning and tire transposition; standard transposition method is the same side before and after transposition. A car tire 2.5 in winter, 2.2 in summer, the highest pressure tire can withstand the tire side, reasonable pressure of tire mark maximum pressure of 70%-80%, but it is best not to pressure higher than the maximum pressure of tire mark.

Q: Can domestic pumps make car tires?: The household inflator can only be used in emergency, and it will not reach the standard air pressure. So, when it is inflated, it will have to inflate to the repair shop, and let the automobile tire be charged to the standard air pressure.
