Summer temperatures rise, the impact of thermal expansion and contraction of the tires, the overall expansion, the internal pressure increases, the carcass will become thinner, increasing the chance of tire puncture, it is learned that the accident on the highway 46% is due to tire failure, While the puncture accounted for 70% of the total accident.
In addition to the high temperature of the air, the ground temperature will be significantly higher than the temperature, the tire directly with the ground contact, not only will reduce the cooling efficiency, but also due to friction produce a lot of heat, resulting in tire temperature is too high, the same increase in tire puncture probability.
First to confirm that the front wheel puncture or rear tire? Puncture as a new car is learning how to deal with?
If the front face puncture, then the hands can not touch, be sure to shake the steering wheel, adjust the direction of the front, the action can not be too large or too much. In addition, the more can not be anxious to brakes, and other vehicle speed gradually down, then the vehicle driving into the emergency lane, and then in the car after the distance (100-200 meters) placed warning triangle.
If the rear tire, the car will be a partial movement of the tire, then the throttle should be slowed down the speed of the car down. It is worth mentioning that, with the front wheel puncture is not the same, because the rear wheel does not have a guiding function, and the general car was later load is relatively high, so the rear tire is not very dangerous, only need to hold the steering wheel.
How to prevent puncture?
The summer tire pressure reduction in the control of about 10% of the most suitable summer high temperature hit, the road temperature, tire pressure is easy to rise, once the tire pressure is too high, it is easy to accelerate tire wear, causing puncture. If the owner of the funds are more abundant, but also for the tire and spare tire nitrogen. Nitrogen is an inert diatomic gas, the chemical properties are extremely inactive, the coefficient of thermal expansion is low, the thermal conductivity is low, and the degree of volume expansion is much lower than that of air when the temperature changes. Nitrogen filling the tire when the deformation is small, improve the grip capacity, reducing the rolling resistance and reduce fuel consumption.
Hot weather, in the high-speed road generally open two hours after the car will stop, but can not sprinkle on the tires to avoid tire deformation. At the same time to pay attention to half-way stop to let the tire break down to cool down. To cool down the tire, let the natural cooling, can not be used to pour cold water on the tires and other means, this will make the tire cracks, shorten the tire life.
Try to avoid rapid acceleration and rapid braking when the temperature reached 35 ℃ to 37 ℃, the car speed of 100 km or more high-speed driving, prone to puncture accident. In the long-distance, high-speed driving, should try to avoid rapid acceleration and emergency braking, because such a move will make the tire "capacity" smaller, increase the tire wear and increase the instantaneous pressure to cause puncture. So the owners in the long-distance, high-speed driving should be developed in the speed of driving habits.
Parking should ensure that all four stops at the same level of the ground, must not park the car in a high and one low on the road. Otherwise, the tires at the lowest will be subject to excessive pressure, resulting in damage to the tire due to deformation of the tire inside the tire.
