Many cars, especially off-road vehicles, have spare tires. These tires are designed to avoid puncturing on the road. However, owners often overlook the maintenance of spare tires. Here are seven things to learn about using the car spare tire.
1, the spare tire has not been used for a long time but also to replace a lot of owners believe that as long as the spare tire has been placed in the trunk does not use, you can "longevity", this is wrong. There are often cases where the owner wants to replace the spare tire after a puncture, but he finds that the spare tire has been severely deteriorated after it has been placed for many years and is already a scrap tire. Auto-cosmetic experts say that tires are rubber products. Aging occurs when they are stored for a long time. Generally, the aging period of tires is about 4 years. Therefore, the spare tire should be replaced after 4 years.
2. Regular inspections of spare tires during daily maintenance or before long-distance travel have rarely been performed by the owner of the spare tire, and some unprofessional repair shops often neglect this point. The spare tire inspection is mainly to check the tire pressure and whether there is wear and cracks, and to replace the tire as soon as possible before the tread wears to the wear mark line. If there is a small crack on the side of the tire, you cannot use it to run long distances or high-speed traffic, because the sidewalls of the tire are thin and high-speed traffic is prone to puncture.
3, the spare tire should not be used for a long time in fact spare tires are used in emergency, not long-term use of tires. The spare tire is wide and narrow. Manufacturers have special requirements for production and use. The spare tire is not worn on the car for a long time and there is no wear. Therefore, a tire that is not worn out is not the same as a tire that has been worn out. The use of the spare tire in the vehicle itself has a certain safety risk.
In the course of use, the user cannot replace the original tire with the spare tire after the car has run for several kilometers. Because the production time of the spare tire and the original tire are different, the tire aging, hardening degree, lifespan and deformation are all different, so it is unsafe to use it for a long time. The spare tire should be replaced with the original tire in time after emergency use.
4. When the spare tire is used, it needs to adjust the air pressure. The tire pressure is not the same as the right tire. Before using the spare tire, you should use a barometer to adjust the spare tire pressure. Normal low tires have a tire pressure of between 2 and 2.2 "barometric pressures," while spare tires are between 2.7 and 3.2 "barometric pressure." One is to ensure the shape of the high-pressure spare tire, and the other is to reduce the probability of a flat tire during high-speed driving, but it cannot be used for a long time and at a high speed. After the owner has replaced the spare tire, he should promptly find a professional to adjust the tire pressure and adjust the pressure to a safe state (around 2.7 MPa).
5, the spare tire should not be placed together with corrosive items The main component of the tire is rubber, and rubber is most afraid of all kinds of oil erosion. Owners often store lubricants and other oils in the trunk. Once the tires touch the tires, they will distort the tires, which will greatly reduce the service life of the tires. If the tire is oily, wash it with a neutral detergent in time.
6, the spare tire should not participate in the adjustment of the tires in the store for the original tire replacement is strictly required, the spare tire is even more inappropriate to participate in the adjustment. Tyre tuning itself is weighing trade-offs in different parts of the tire, and it is no longer advisable to adjust tires. There are also different problems of wear and tear between the front and rear tires. Because of the different wear and tear of the spare tire, participation in the tire adjustment will increase the security risk.
7. The repaired tires should be placed on the rear wheels. Some owners will use the repaired tires as spare tires. If these tires are to be used again, they must be placed on non-drive wheels. Generally, we drive the intermediate and lower vehicles. All are front-wheel drive vehicles, and since the direction of the car after the front tires is more difficult to control, the repaired tires should be placed on the rear wheels. In addition, when using spare tires, especially small-sized spare tires, pay attention to the control of the vehicle speed. Normally, it should not exceed 80 km/h.
Remind the majority of riders to pay attention: also routine inspection of the spare tire, do not wait until a tire accident, remove the spare tire only to find that the spare tire can no longer be used.
