How to maintain tyres in summer
Pay more attention to tire pressure
Summer is coming, with the temperature rising, the number of tire blowout accidents is also increasing. Usually when driving, especially when driving far away, don't forget to bring a tire pressure gauge with the car, so as to check the tire pressure at any time.
It is advisable to check the tyre pressure of all tyres at least once a month, including the spare.
If the air pressure is reduced too fast during each driving, check whether the tire is nailed, whether the air nozzle rubber is aged, cracked and other conditions. If these conditions are found, go to a professional repair shop in time for treatment.
When the tire is worn to the wear mark, it needs to be replaced
At this time, the drainage performance of the tire will be greatly reduced, which will seriously affect the wet grip performance. In addition, if the wear is uneven, it may be due to wheel alignment imbalance, which not only shortens tire life, but also affects vehicle handling. It must be adjusted or replaced immediately.
Prevent tire corrosion
Tires are rubber products, so try to avoid contact with oil, acid and other chemicals. Because these products will cause tire corrosion, deformation, softening and other problems.
In those days when the temperature is rising, it's better to park in the shade to avoid direct sunlight, which may cause premature tire aging.
Try to avoid hitting hard objects
When a tire hits a pothole or a curb, it will crush and deform the tire, causing a bulge. In serious cases, the sidewall of the tire will be broken or deflated. So try to drive carefully to avoid the potholes on the road. If you can't get around, you should slow down and pass slowly.
How much tire pressure is suitable in summer
Generally speaking, there will also be tire pressure related signs on the tire, indicating the maximum tire pressure that the tire can accept. According to the principle of thermal expansion and cold contraction, it can be adjusted 0.1-0.2 lower than the normal value in summer and 0.1-0.2 higher than the normal value in winter. Please refer to the car manual for normal value requirements here. In winter, it's better for car owners to often clean up the inclusions in the tread. It's hard to avoid solid impurities left in the tread, which may cause the tire to crack or lose heart.
In summer, the tire pressure is usually between 2.2-2.4 kPa, which should be normal. In spring, the tire pressure is usually kept between 2.3-2.5 kPa at about 20 ℃. However, with the gradual increase of temperature and road temperature, high-speed or long-distance travel, the tire pressure is very simple to rise, and the tire burst is simply caused. In order to be safe, the parking should be depressurized at this moment.
In summer, the road temperature will probably reach 60-70 degrees Celsius. If the tire pressure is too high when the car is traveling on the road, it is very easy to blow out when it slightly touches the thin part of the tire. So it's better to keep the tire pressure of the car at 2.2kpa.
The high tire pressure reduces the touch area between the tire and the ground, and the accepted pressure and wear per unit area increase sharply. The brake simply becomes out of control, and explodes in case of bumps or depressions on the ground, damaging the suspension system of the car, and uncomfortable riding.
