Classification According to Application
(1) Regular Tire
Also called a ground tire that is not for emergency use.
(2) All Season Tire
When a regular tire has been damaged by a flat or other reason and cannot be used, the emergency tire may be used temporarily. Emergency tires can save trunk space and reduce the weight of the car. There are two types of emergency tires:
(a) Foldable emergency tires
(b) T-type emergency tires
Emergency tires are manufactured only for use in emergencies and cannot be used at speeds of over 80km/h. The pneumatic pressure has to be maintained at 60psi and the air pressure should be checked at least once a month.
(3) Run Flat Tire
Even when the air pressure within the tire reaches zero due to damage such as a flat, this tire can be used to drive 80km at 80km/h speed to a location where a tire change can be made.
