Today we will talk about "The Story of Xiaobian and the Spare Tire", hello! What do you want! I'm talking about a story with a car spare tire! Of course, before that, we must first understand the daily maintenance and use precautions of the dongfeng ix5 spare tire.
1. What are the types of spare tires?
1. Full-size spare tire The full-size spare tire is exactly the same as the existing tire specifications and can replace any tire on any car.
Someone asked, since the main parameters of the full-size spare tire are the same as the original tire, can it be used as the original tire? The answer is NO. The full-size spare tire and the non-full-size spare tire are essentially the same, and they are just an emergency. Although the specifications of full-size spare tires are the same as those of common tires, the rubber raw materials and manufacturing processes used can only meet short-distance, medium- and low-speed driving.
2. Non-full-size spare tires Non-full-size spare tires are one size smaller than the original tires. In addition, this kind of spare tires can only be used on non-driving wheels, and the maximum speed does not exceed 80km/h, and the driving does not exceed 50km. limits.
3. There is also a special kind of spare tire hidden in the tire, that is, the zero pressure spare tire, which is what we commonly call the explosion-proof tire. Even if the tire is scratched, it can still maintain the driving profile for a certain time and speed, and temporarily stabilize your dongfeng ix5 to the repair station.
Second, does the spare tire have a service life?
I have never encountered a flat tire, so the spare tire has not been used. Can I keep it on for future use? Of course not. Generally, the storage period of spare tires is about 4 years, especially the spare tires placed on the chassis and externally mounted. After the expiration date, even if the surface is the same as the original, the rubber/texture is actually aging, and it will increase the puncture rate after use. Always pay attention to check for fine cracks and bulges.
3. Precautions for use 1. Regular inspection of spare tire tire pressure. Spare tire inspection is mainly to check tire pressure, whether there is abrasion and cracks. Before the tire pattern wears to the wear mark line, the tire should be replaced as soon as possible. If there are small cracks on the sidewall, you cannot use it to run long distances or high-speed driving, because the tire sidewall is thin, and high-speed driving is prone to puncture.
2. Do not put the oil together with the spare tire. If the tire gets oily, wash it off with a neutral detergent in time. Because the main component of tires is rubber, and rubber is most afraid of the erosion of various oils. Owners often store lubricating oil and other oils in the trunk. Once the oil gets on the tires, it will bulge and corrode the tires and reduce the service life of the tires.
3. Put the repaired tires on the rear wheels. Generally, the intermediate and lower vehicles we drive are front-wheel drive vehicles. If you want to use repaired tires or spare tires, they must be placed on the non-driving wheels, and the front tires are blown out. The direction of the tire is more difficult to control, so the repaired tire should be placed on the rear wheel. In addition, when dongfeng ix5 uses a miniaturized spare tire, pay attention to controlling the speed of the vehicle, under normal circumstances it should not exceed 80 km/h.
