The car spare tire is used as a relatively unknown configuration on the car, and can only be exposed in the case of a “original†puncture. At present, car spare tires are mainly based on non-full-size tires, and there are also a small number of full-size and zero-pressure tires. Everyone knows that spare tires for cars cannot be used for a long time. Why is it necessary to have spare tires of non-full size? 1 Difference between non-full size spare tire and full size spare tire Non-full-sized spare tires are smaller in diameter than standard tires, and they are narrow in width and relatively poor in grip, so they can only be used as temporary replacements rather than long-term use. Moreover, the non-full-sized spare tire has a smaller occupied space and a lighter weight, and can still be used in case of basic emergency. In contrast, the full-size spare tire has the same length and width as the standard tire, and grip is closer to that of the original tire, resulting in more stable driving. Even so, full-size spare tires, like non-full-sized spare tires, cannot be used for a long period of time and can only be used as an emergency. Because the spare tires and standard tires replaced by the new ones have different speed grades and load-bearing indicators, long-term use of them will easily lead to high-speed tire bursts. 2 Why are cars equipped with non-full-sized spare tires? First, the cost savings: Compared to the vehicle's original tire and full-size spare tire, the cost of non-full-size spare tires is much lower. For the auto manufacturers, each spare tire can save a lot. Second, space assurance: spare tires for cars are mostly placed at the bottom of the trunk. Compared to full-size spare tires, non-full-sized spare tires are smaller and more space-saving. Third, most SUVs and MPV models will have the spare tire fixed on the chassis. In this case, the smaller non-full-size spare tire will not affect the passing of the vehicle. Fourth, the role of safety warning: the use of non-full-size spare tire, to remind the owner to repair and replace the tires in a timely manner to avoid prolonged use of the spare tire and bring safety hazards to the vehicle. If you use a full-size spare tire, the owner will often Fortunately, it can be used day by day, thinking that it is possible to drive carefully. This is very dangerous. Advice: Whether it is a full-size or non-full-sized spare tire, it can only be used as an emergency, so don't use it for a long time. In addition, once the spare tire is installed, the maximum speed at which the vehicle travels should not exceed 80 km/h, and the distance traveled must not exceed 100 km. Therefore, after replacing the spare tire on the expressway, it is necessary to first approach the next high speed, find the vehicle maintenance point to replace the automobile factory tire, and then continue driving.
