Does this car have a spare tire? What should I pay attention to when changing a spare tire?

There are very few cars without spare tires, which are divided into two extremes. The first batch of small or miniature hatchback scooters (including a few entry-level joint venture vehicles) are mostly below 50,000. These cars need to strictly control the production cost because of their low price positioning. The simple matching degree is often exaggerated, and most of them only retain the basic driving function. Among them, Baojun 3 10 low configuration and discontinued Chevrolet Knight low configuration are more representative. If you want a spare tire, you can only choose or install it later.

Some low-end cars are not equipped with spare tires in order to reduce costs and guide prices. Use explosion-proof tires. Explosion-proof tires are generally used in luxury high-end models, such as BBA models. Even if there is a flat tire, the vehicle can run as usual. So there is no need to equip explosion-proof tires. The principle of RSC tire exhaust protection is simple. This kind of tire supports the shape of the tire by strengthening the sidewall thickness and relying on structural strength. The sidewall thickness of HT road tire is only about 6mm, and the thickness of exhaust protection tire is always several times higher. Therefore, although there will be some bumps after exhaust, the tires can still show medium and high speed performance in a short distance, which is why vehicles equipped with RSC tires do not need spare tires.

Except for low-end cars, cars without spare tires are high-end cars. Most household scooters that use ordinary road tires have spare tires. The spare tire is located in the car or SUV. For example, if you open the trunk floor, you can find the spare tire and the vehicle tire changing tool. Most of MPV light buses and pickup trucks are behind and under the chassis, that is, under the trunk. When disassembling, it is necessary to find the fixing bolt holes from the inside of the trunk, which are usually covered with detachable decorative plates.

If your car has no tires, congratulations, it means that your car has special tires! Either you have a flat tire or you run after a flat tire! Either mend your own tires, not afraid of pricking! The so-called run-flat tires are usually called explosion-proof tires. This kind of tire has a particularly thick sidewall. Even if there is no air, the hub is still supported by the tire side and the tire will not be removed. As long as the speed does not exceed 80 km/h, it is safe! One disadvantage of this kind of tire is its poor comfort. The so-called self-repairing tire is called "no leakage, no repair for life". This kind of tire is coated with a special material on the inside of the tread. When punctured, this special material is injected into the leak through the air pressure in the tire to automatically repair the leak. However, when the nail passes a certain limit (for example, 8mm), it will still leak, and the shoulder or sidewall of the tire will be damaged.
