Are you concerned about car tire maintenance? Most people pay attention to car maintenance in the engine room and the daily comfort required, but only a few people care about the maintenance of the tire. Car tires are the foundation of the car. It is not only the fuel consumption of the car, but also the safety of driving.
Before curing, deal with the basic understanding of tires. Specification Meaning for example: 215/50R1791V
215 - refers to a tire width of 215mm;
50 - refers to the flat tire ratio, that is, the height of the section is 50% of the width;
R—refers to the tire as a radial tire (this tire inner layer is a radial tire manufacturing method);
17 - refers to the rim diameter is 17 inches;
91 - refers to the load index 91, which represents the maximum load of 615 kg for this tire, and four tires is 615 × 4 = 2460 kg;
V - refers to a speed class of 240 km/h.
Learn to Diagnose Tire Health Most vehicle owners know that tire wear and bulging need to be replaced immediately. Therefore, proper inspection in daily use is even more critical. The owner should check the tire regularly. The inspection includes tire pressure, tire tread wear, tire bulging, and removal of small stones in the tire joint.
1. Knowing the date of manufacture and life of the tires As with most other consumer parts, car tires need to be replaced on a regular basis. When it comes to this, it reminds people of Paul Walker. The accidents that occurred on him and the nine years of use are serious and old. Related to the tires. Therefore, whether it is a new car that has just been purchased or a car that is already in use, it is necessary to clearly know the life of the tire.
In the tire peripheral information, in addition to the tire brand and size, clearly marked the tire production time. The tires after 5 years from the factory should be promptly replaced regardless of their appearance.
2. Testing tire pressure Each vehicle body has the standard tire pressure value given by the manufacturer to the vehicle. Most of them are marked on the side of the driving door, with the exception of some models. The tire pressure value needs to be strictly observed in daily use. Many models are equipped with a tire pressure monitoring system, but a vehicle that is not equipped with this system should develop the habit of measuring the tire pressure once a month, if the road is often under poor road conditions. On the road section, the frequency of detection should also be appropriately increased.
No tire pressure monitoring system owners can purchase tire pressure gauges on the Internet. The price ranges from 20 yuan to over 100 yuan. The most basic can be used in home situations. It should be noted that the tire pressure check must be carried out with the tires in a cool state. .
3. Observing the wear of the tire The determination of the tire wear condition is very simple. There will be a trapezoidal rubber boss at every 30 degrees in the main drainage groove of the tire tread. When the tire tread wears to be flush with the mark, the tire must be replaced. Drop it. Secondly, if the climate in the region is rainy, in order to prevent the vehicles from slipping on the accumulating surface, the tread pattern depth requirement should be higher.
4. The "sidewall" is easy to ignore. The thickness of the tire sidewall is much lower than that of the tread. Therefore, if the sidewall is injured, it is easy to have a puncture. Every day when driving, care should be taken to protect the sidewalls. Whether it is pit roads or road teeth, it should be driven slowly. Do not collide with the sidewall as much as possible.
5, these damages can not repair tire repair:
(1) Tie the nail and the hole diameter of the nail is more than 6mm.
(2) Shoulder or sidewall screws, cracks or leaks.
(3) After tire blowout using the tire reinforcement technology, the low tire pressure traveled a certain mileage.
(4) Ordinary tire bolting leaks close to zero tire pressure for a certain mileage.
