Why does the car still pull to one side when the four-wheel alignment data is correct?

[PeytonLynn]

The four-wheel alignment data is correct but the car still pulls to one side because the tire tread patterns on both sides are different or the tread depth is uneven. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are rubber products and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low. Tires can also age if left unused for long periods, so it's important to check the production date when purchasing new tires.
