What is the usage method of a spare tire?

[Johnny]

The usage method of a spare tire is as follows: 1. The spare tire should not be used for a long time. Generally, the spare tire of a vehicle does not experience tread wear during long-term driving, so its friction level is definitely different from that of regular tires. Long-term use can easily cause issues such as vehicle deviation and uneven friction with surrounding tires. The color of the spare tire is usually bright to remind the owner not to use it for an extended period. 2. The spare tire should not be used on the front wheels. The spare tire is generally meant to replace the rear wheels. If a front wheel fails, it is best to move a rear wheel to the front and then install the spare tire on the rear wheel. This is because the front wheels bear more weight and friction when encountering obstacles, increasing the risk of a blowout. Using the spare tire on the rear wheel enhances safety. 3. Drive within the speed limit for the spare tire. The spare tire should not be driven faster than 80 km/h or for long distances exceeding 150 km. After replacing a faulty tire with the spare, the regular tire should be replaced as soon as possible. The quality and air pressure of the spare tire differ from regular tires, and driving too fast or for too long poses safety risks. 4. Understand the air pressure and size of the spare tire. Since the spare tire is rarely used, knowledge about it is often limited. This can lead to confusion when a spare tire is needed. Different vehicles have different spare tire specifications. It is important to be familiar with the size, rim, air pressure, and condition of the spare tire beforehand so that you are prepared when needed. 5. Regularly inspect and replace the spare tire. Even if the spare tire has not experienced major issues, it is still exposed to environmental temperatures and other factors during long-term driving, which can cause aging or insufficient air pressure. Regular inspections and timely replacements are necessary. 6. Do not store the spare tire with corrosive items. The spare tire is often kept in the trunk alongside various items and may come into contact with oil or other corrosive liquids. This can accelerate the aging of the tire. When the spare tire is needed, it may not function properly and could even become a new hazard.
