What does outslde mean?

[VanKeegan]

outslde indicates that the tire has a specific direction and cannot be installed randomly. It specifies the installation direction of the tire, serving as a directional indicator for unidirectional and mixed tread pattern tires. Below is relevant information about tires: 1. Shelf life: Since car tires are made of rubber, they have a certain shelf life. However, unlike food products, they do not have an explicitly labeled expiration date because the shelf life is highly dependent on actual usage conditions. If the driver does not have poor driving habits such as sudden braking, abrupt stops, or sharp turns, the shelf life of car tires is generally 3-5 years. 2. The newer the tire, the better its performance: Tires with more recent production dates have better performance and a longer shelf life, while tires with older production dates have poorer performance and a shorter shelf life. It is best to purchase tires with a production date within one year. Tires with a shelf life exceeding 3 years should not be purchased, as they have already begun to age, leading to a significant decline in performance and posing safety hazards if continued to be used.
