What is the impact of rear wheel toe-in on vehicles?

[LeLeo]

Rear wheel toe-in affects vehicles by causing tire wear and shortening the tire's service life. Below is relevant information about rear wheel toe-in: 1. Definition: Rear wheel (or front wheel) toe-in is a task very familiar to automotive repair technicians, as wheel alignment must be checked during vehicle maintenance. 2. Function: Toe-in refers to the difference between the rear distance value and the front distance value between two wheels, or the angle between the tire centerline and the longitudinal centerline. The purpose of front wheel toe-in is to ensure the vehicle's driving performance and reduce tire wear. When tires roll, their inertial force naturally causes them to tilt inward. With proper toe-in, the tilting direction during rolling is offset, thereby reducing uneven wear on the inner and outer sides of the tires.
