Do tires have a correct side for installation?

Tires do have a correct side for installation, especially when the tread pattern is asymmetrical or unidirectional. It is crucial to install the tires strictly according to the specified direction indicated on the tire. Installing tires incorrectly can lead to reduced grip, uneven resistance on both sides, which in turn decreases braking efficiency, accelerates tire wear, and may cause the vehicle to pull to one side or result in unstable steering. On the sidewall of an asymmetrical tread tire, you can find the word "OUTSIDE," indicating that this side should face outward. Similarly, there is an "INSIDE" mark on the inner side, indicating that this side should face inward.
When changing tires, I noticed that some tires do require distinguishing between the front and back sides for installation. For example, directional tires have rotation arrow markings, and the arrow must point in the direction of travel; otherwise, the drainage performance in rainy conditions will be poor. Asymmetric tires also need to have the inner and outer sides aligned correctly, with the inner side usually marked with 'inside.' If installed incorrectly, the noise while driving will be significantly louder, the tread will wear unevenly, and the tires may lose grip on wet or slippery roads. I once encountered this situation when a tire shop worker accidentally installed them incorrectly. After driving for a few weeks and feeling unstable steering, I returned to the shop for an inspection and had it corrected. I recommend paying close attention to the markings when changing tires yourself, and if unsure, seek professional help to ensure driving safety.
