Tires, as the only part of the car that is in direct contact with the ground, are closely related to our driving safety, so most drivers pay great attention to the maintenance of tires when driving. Not only to check the tire tire pressure regularly, but also to do four-wheel alignment of the tire on a regular basis. In fact, in addition to paying attention to the maintenance of car tires, we must also pay attention to the maintenance of car spare tires. Car spare tire also plays a very important role in daily driving, today Xiaobian will give you a good talk about the relevant knowledge of car spare tire maintenance.
Spare tire refers to the spare tire prepared for the car, spare tire is generally divided into non-full-size tires and non-full-size tires. Whether it is a full-size tire or a full-size tire, it cannot be "long-lived". Because non-full-size tires and full-size tires are rubber products, they will age once they are stored for too long. The "tire age" of the general tire is about four years, so we need to replace the spare tire every four years to prevent the tire from being seriously aged and unusable.
So what do we usually need to pay attention to when maintaining the spare tire? First of all, we must remember to check the spare tire condition regularly to be prepared. Spare tire inspection mainly includes tire pressure inspection and tire wear, if the spare tire tire pattern wear is very bad, be sure to replace the spare tire as soon as possible.
Secondly, when we store the spare tire, we must pay attention to try not to put the oil and the spare tire together, because the rubber products are most afraid of being placed together with corrosive substances. Once the oil is dripping onto the spare tire, it will cause the spare tire to expand and erode, thereby reducing the service life of the spare tire.
In addition, we should also pay attention not to use the spare tire for a long time, because conventional tires are optimal in terms of fuel consumption, grip, tire noise, etc., which can maximize the performance of the car. The spare tire is the tire that is replaced in the emergency, and if it is used for a long time, there is a certain safety hazard. In particular, the non-full-size spare tire is one size smaller than the tire of the vehicle itself, and it cannot be used for a long time, the general driving distance cannot exceed 50km, and the maximum speed during the driving process cannot exceed 80km/h.
In addition to not being able to use it for a long time, the spare tire of the car cannot be used on the high speed. This is because the degree of wear of the car spare tire pattern is not the same as the wear degree of the other three tires, which may cause the vehicle to deviate when driving, and it is very dangerous if it is on the high speed.
So how do we usually replace the spare tire correctly? First of all, we must use the jack to lift the car, and put the spare tire upside down on the bottom of the car to prevent the jack from suddenly falling off and causing damage to the car. Then remove the faulty tire and install the spare tire, we should pay attention to the diagonal order when installing the tire, and tighten all the fastening nuts evenly. Finally, lower the jack and slowly lay the car flat. However, the spare tire cannot replace the use of the original tire for a long time, so after replacing the spare tire, we must go to the nearest auto repair shop in time to replace the conventional tire.
Proper use and maintenance of the car spare tire is very important for every driver, so we must remember the above knowledge about the spare tire.
