Can the spare tire be used as a normal tire?

What everyone thinks about "spare tires"

There are many errors

Misunderstanding 1: Use a full-size spare tire as a normal tire

As we all know, there are generally two types of spare tires, one is a full-size spare tire and the other is a non-full-size spare tire.

In order to reduce weight, reduce space occupation, and facilitate the distinction between normal tires and spare tires, most of the spare tires produced by automobile manufacturers on the market are not full-size tires.

At the same time, it is also to better remind everyone not to mix up the tires and forget to replace them with normal tires that have been repaired when changing tires. Therefore, non-full-size tires must not be used as normal tires.

But some people may think that a full-size spare tire has the same tire width as a normal tire, so it can be used as a normal tire.

No! you are wrong! Although the tire width is the same, it does not mean that its parameters are exactly the same as normal tires. The tire texture, speed level, load-bearing index and other parameters are different. A full-size spare tire cannot be used as a normal tire for a long time, especially when driving at high speed, which will bring danger to the driver and passengers.

When the wear degree of the full-size spare tire is very different from the main tire or the service life is very different, it cannot be used directly to replace the main tire. It may easily cause the vehicle to deviate at high speeds, and the tire may also cause eccentric wear, so it can only be used in emergency situations.

Misunderstanding 2: “The spare tire has never been used, it’s just like new”

No, no, you are wrong again! Spare tires actually have a shelf life.

Some car enthusiasts may feel that the spare tire is always kept in the trunk and does not fall to the ground. It will not be worn and is just like new. Youbao reminds everyone that this concept is wrong.

Although car spare tires are rarely used, they are rubber products like ordinary tires. They have a shelf life, usually 3 to 5 years.

If it is more than 5 years old, the performance of the spare tire will be greatly reduced. At this time, the spare tire will age and crack, deteriorate in toughness, and deteriorate in performance. If it is not replaced in time and the spare tire is replaced with a degraded spare tire when the tire bursts, it will seriously affect the safety of the car owner.

Therefore, Youbao recommends that everyone must replace the spare tire in time~

At the same time, in order to extend the service life of the spare tire, during the 5-year shelf life, the spare tire must be regularly tested and cleaned. Do not put oil and spare tires together, because the spare tire is a rubber product, and the oil will corrode the rubber. , this will shorten the service life of the spare tire; on the other hand, it is recommended to check and measure the tire pressure from time to time in case of emergency use.

What you need to know about spare tires

Be sure to read the car manual. The manual will generally remind you that after replacing the spare tire, the vehicle speed cannot exceed 80 km/h. The spare tire can only be used in emergencies, and it is necessary to replace it with the original normal tire as soon as possible.

Due to the smaller grip, the non-full-size spare tire can be installed without driving wheels as much as possible, so that it is less likely to deviate when the vehicle is driving.

When maintaining your vehicle, you should also remember to inflate the spare tire. If the spare tire is stored stationary for a long time without being used, the tire pressure will rise and fall. Maintaining normal tire pressure will also help extend its life.
