Some tires indicate a directional rotation on the sidewall. Some tires have specific side that should be inside or outside. Some tires are a combination of both. It is important to mount the tires properly according to the direction.
Directional – indicates that the tires should rotate in the direction the arrow is pointing
Asymmetrical – there is a word “outside” and “inside” labeled on the sidewall. “Outside” must be facing outward from the vehicle.
Directional Assymetrical – combination of both directional and asymmetrical tires.
