What is the replacement standard for sidewall scratches on tires?

[DeAiden]

The replacement standard for sidewall scratches on tires is ≤2mm, which is acceptable for use, while ≥3mm is recommended for replacement. The sidewall of a car tire is the weakest part in terms of strength but also the most prone to damage. This is because sidewall parking is most likely to cause scratches, and running over debris while driving can easily damage the sidewall rubber. Below is some relevant information about tires: 1. Tire classification: Car tires can be categorized into more than 10 types based on their use, such as passenger car tires, truck tires, and off-road tires. Structurally, they can be divided into radial tires, bias tires, full-size spare tires, and non-full-size spare tires. 2. Tire characteristics: Car tires have different characteristics depending on their use. Passenger car tires offer higher comfort, while off-road tires provide better road passability. When selecting a car, it is important to consider the road conditions where the car will be driven to avoid choosing the wrong type, which could affect tire performance.
