How Long is Considered as Stock Tires?

[Hernandez]

Tires that have been manufactured for more than 3 years are considered as stock tires. Below is relevant information about tires: 1. Wear: Tires have wear indicators. There are triangular marks on the side of the tire. When the tread wears down to the level indicated by the triangle mark, it is recommended to replace the tire. There are also raised marks inside the tire's tread grooves. When the tread wears down to the level of these raised marks, the tire should be replaced. Simple punctures can be repaired without the need for replacement, but bulges must be replaced. 2. Aging: Rubber oxidizes in the air, and oxidized rubber becomes hard, thereby reducing grip. Therefore, even if a set of tires is not used, its lifespan will decrease. It is not recommended to use tires for more than 5 years from the date of manufacture. The manufacturing date can be found on the side of the tire.
