Did you do the right tire maintenance?

According to international driving safety surveys, traffic accidents in rainy days are about 5 times higher than usual. Summer rains have a lot of rainfall, the roads are slippery, and the adhesion of tires has dropped. This has put a big test on car tires. At the moment when the weather between summer sun and rain crosses, the tires will “grind the ground” in the hot sun and suffer from the erosion of rainwater. The dual test requires the owner to carefully maintain, otherwise, if a flat tire occurs, it may lead to a safety accident. .

First, the speed is very important

First of all, on roads with poor road conditions, do not start too aggressively so as to avoid tread wear due to tires and ground dragging. When the vehicle is descending, the appropriate speed should be controlled according to the size, length, and road conditions of the slope. This can be avoided. Or use less emergency braking to reduce tire wear; vehicle cornering should be based on curved road conditions, turning radius, generally appropriate deceleration, so as to avoid the role of inertial force and centrifugal force, to accelerate the unilateral tire wear.

When you drive up a bumpy road, you must choose the road surface to reduce the impact between the tire and the road surface and avoid damage to the machine and tires. Second, slow down and avoid tire bumps and strong vibration; through muddy areas, should choose a more solid, non-slip through the place, so as not to subsidence tires, idling in place, severe vibration caused severe tires and sidewall cuts, scratches.

Second, parking should be correct

In high-temperature weather, when the vehicle is parked, it should be kept in a cool, ventilated place as much as possible. It is better to wait for the temperature of the car body to naturally decrease. Do not park the car directly under the sun. Do not rush to cool the tire with cold water. It is best to fill the tires with nitrogen, because the gas in the tire itself is a common gas. Since nitrogen is an inert gas, it is not easy to add nitrogen to hot tires. Tires should be kept away from sources of heat, power generation equipment, and ozone, and must not be too close to oils, combustibles, and chemically corrosive chemicals. If you encounter a puncture, do not slam the brakes. Instead, you should lightly “spot” the brake while holding the steering wheel with both hands. Keep the car as steady as possible, and slowly pull over to stop.

Third, tire pressure can not be ignored

First of all, tires should be inflated according to the “air pressure load correspondence table” specified in the national standards. After the tire is inflated, check whether any parts are leaky. If leaks are found, repair it in time. Secondly, the tires must ensure normal internal pressure during use. When running or working for a long time, check the tire pressure regularly. Again, when parking for a long time, the front and rear axles must be erected. High air pressure, tires are easy to wear, the top explosion; low pressure, tires are easy to deformation, grinding bad. When the twins are installed together, the inflation of the two children should be the same, and one air pressure and one air pressure can not be high. Finally, summer tire pressure should not be high. Some owners believe that summer temperatures are high, thermal expansion and contraction, tire pressure is certainly higher than in winter, easy to puncture by heat, so the tire pressure should be low. Some owners believe that if the tire pressure is reduced, the friction between the tire and the ground will increase exponentially and the temperature of the tire will rise sharply. If the vehicle runs at a high speed, it may cause a puncture. Therefore, summer tire pressure should be high. Should the tire pressure in summer be high or low? In fact, reducing tire pressure will have two consequences. First, grinding tires will shorten tire life. Second, fuel consumption will increase. However, reducing tire pressure will also reduce the risk of puncture. In summer, due to high temperatures, especially when driving at high speeds, when the speed reaches 100-120 yards, the tread temperature will reach 80°C, or even exceed 100°C, and the internal pressure will increase. The only use for increasing tire pressure is to reduce fuel consumption. However, increasing the tire pressure may increase the braking distance in addition to possible punctures, which is detrimental to safe driving. Therefore, summer tire pressure should be low.
