How to distinguish the inside and outside of a tire?

[LaJanelle]

Ordinary car tires do not have a specific inside or outside. The methods to distinguish the inside and outside for certain tires are as follows: 1. To facilitate the observation of tire parameters such as model and production date, manufacturers usually install the side with the printed production date on the outside. 2. There is another type of tire called a unidirectional tread pattern tire or an asymmetric tread pattern tire, which has a strict installation direction. The inside and outside of such tires can be distinguished by their tread patterns. 3. Ordinary car tires do not have a specific inside or outside, and their tread patterns are symmetrically arranged. No matter how they are installed, it will not affect the performance of the car.
