How many kilometers should car tires be rotated front to back?

[VonLila]

1.5 to 20,000 kilometers is the recommended interval for rotation. Below is extended information about tire rotation: 1. When rotating front and rear tires, you cannot swap them randomly. Symmetrical tread patterns can be cross-rotated, while asymmetric and unidirectional tread patterns must be rotated front-to-back only. If the tire wear appears particularly severe, replacement is recommended. 2. Cars are categorized as front-wheel drive, rear-wheel drive, and four-wheel drive. During driving, the force distribution on the tires varies. For four-wheel drive vehicles, if the front tires are excessively worn, they can be directly swapped with the rear wheels. However, for front-wheel drive vehicles, the front tires experience more stress due to frequent turning, acceleration, and braking during daily driving, leading to greater wear compared to the rear tires. Therefore, when installing new tires, a diagonal rotation method can be used. Of course, during tire rotation, the degree of wear should be checked. If the wear is significant, rotation should be avoided, and new tires should be installed instead.
