How to Determine the Correct Orientation of a Tire?

[RicardoAnn]

For passenger car tires, there are several standards to determine the correct orientation: 1. For unidirectional tires, mount the tire on the rim according to the rotation arrow indicated on the tire sidewall. The rotation arrow on the sidewall should align with the forward direction of the vehicle. 2. For asymmetric tread tires, when installing the tire on the rim, ensure the side marked with 'outside' faces outward. 3. If the tire has raised white lettering or a sidewall protection layer, install the side with the raised white letters or protection layer facing outward. Consequences of incorrect tire installation: 1. Specifically for asymmetric tread tires, the tread pattern affects noise reduction, handling stability, wear resistance, and wet grip performance. 2. If the tire is mounted inside out, the difference may not be noticeable during normal driving. However, at higher speeds, such as during hard braking on the highway, emergency maneuvers, or driving through wet sections, the tire's grip imbalance will immediately become apparent.
