Passenger Car Tyres Inflatable

Oct 17, 2017

Passenger tire is one of the important parts of the car, it is directly in contact with the road surface, and the automobile suspension to ease when the car the impact, to ensure good take a car ride comfort, comfort and Ensure the wheels and pavement have good adhesion; Improving automobile traction, activity and adoption; With the weight of the car, the important role that tires play in cars is more and more appreciated.

Size classification

1. Full-size spare tire: the size of the full-size spare tire is exactly the same as the other 4 tires of the original car, which can be replaced by any tire that is temporarily or cannot be used.

2, the full-size spare tire: this kind of spare tire tire diameter and width than other four tires slightly smaller, therefore can only be used as a makeshift, and can only be used for the driving wheel, and a top speed of not more than 80 km/h.

Pressure on the classification

Zero-pressure tire: zero-pressure tire is also called "run-flat tire", which is known as "explosion-proof tire", which is literally used as "air-proof tire". Compared with ordinary tires, zero tire after being stung, will not leak or leakage is very slow, can keep outline, the bead can also has been fixed on the rim, to ensure that the car can drive or temporarily stable for a long time to repair. Thus, cars equipped with this kind of tyre will no longer need to carry spare tires, so that the spare tire will be invisible in another way on four tires.

Use skills


(1) the car should not start too fast, and no matter whether it is empty or heavy, it should start at a low speed. Avoid tyre and ground towing to reduce tread wear.

(2) in good road driving, should maintain a straight line, in addition to each other and avoid obstacles, banned from side to side and sharply turned, in case between tire and rim tires produce transverse cutting injury.

(3) when the vehicle has a long slope, the speed should be controlled according to the slope size, length and road conditions. At steep slope length, road, under the condition of complex road conditions, should gear driving, and use the slight brake control speed downhill, such not only can avoid the emergency brake, reducing tire wear, and also have a guarantee for safe driving.

(4) car uphill, should make the most of inertia, timely shifting, the shift in time, nice to keep the vehicle on a proper scope, don't wait for the bus stopped to start again, in order to reduce tire wear.

(5) the vehicle should control the speed according to the curves of turning, don't turn high-speed, larger centrifugal force or vehicles, tilting car goods, side of center of mass migration, unilateral overload drag tires, accelerate the abrasion, at the same time also can make the tyres being round copper transverse cutting, damage.

(6) in complex cases (passing, passing, through the town, the intersection, railway), should grasp the appropriate driving speed, reduce the frequent braking and avoid emergency braking, cause otherwise sliding friction between tire and ground, resulted in the catastrophic tread wear.

(7) the road should be slowed down on the bad road, and carefully observed, the alternative route shall be passed, and whether there is a stone between the two tires should be checked after passing, if any, should be eliminated in time.

(8) stop and stop in the car on the way to make a safe taxi habit. To choose before parking ground smooth, clean and oil free parking on the ground, every tyre should be smooth, especially the vehicle load for the night, more should pay attention to choose good parking place, the rear wheel jacking when necessary.


1. Pay attention to safety. Always check air pressure with air pressure gauge, so as not to inflate the tyre.

2. After stopping, the tire should be reinflated after the tire has been cooled, and the temperature of the tire will rise when the vehicle is moving, which will affect the pressure.

Check the valve nozzle.

4. Pay attention to cleaning. The filling air cannot contain moisture and oil, in case the tyre rubber is damaged.

5, inflatable should not exceed standard too much after deflated, nor because of can't air and too much air in go out for a long time, such as too many more than standard prompt cord excessively stretching, cause its strength is reduced, affect the service life of tires.

Before 6 air valve should be sounded dirt rub-up, don't loose valve core, inflatable after bubble water (or water) applied to the valve mouth, check whether the leak (if the leak can produce small bubbles), and the valve cap or impaction, prevent sediment into the valve inside the mouth.

7. When the radial tire is inflated, due to the structure of the structure, the sinking quantity and the earthing area are both larger, which are often mistaken for insufficient gas and inflated; Or vice versa, because of its subsidence and the earthing area is already larger, in the air pressure insufficient is also mistaken for sufficient. Apply standard barometer to determine. The air pressure of the radial tire should be 0.5 to 1.5 kg/cm.

8. The air pressure gauge used in the vehicle's barometer or the tire shop shall be checked periodically to ensure the accuracy of the air pressure check.
