1. Full-size spare tire for Petrol Car: The standard size of full-size spare tire for Petrol Car is exactly the same as the other 4 tires of the original vehicle, and it can replace any tire that is temporarily or no longer usable;
3. Zero-pressure tire: Zero-pressure tire is also called safety tire, which is what we commonly call "explosion-proof tire", and the industry directly translates it as "run-flat tire". Compared with ordinary Changan Car tires, zero-pressure tires will not leak or leak very slowly after being punctured, and can maintain the running range.
The tire bead can also be fixed on the rim all the time, thus ensuring that the Changan Car can travel safely to the maintenance station for a long time or temporarily. Therefore, Petrol Car equipped with this tire no longer need to carry spare tires, so that the spare tires are invisible on the 4 tires in another way.
