Does Parking with the Steering Wheel Not Straightened Have Any Impact?

Parking with the steering wheel not straightened does have impacts, including: 1. It causes uneven force distribution on the tires, accelerating the aging and deformation of the tire sidewalls, leading to air leaks or blowouts; 2. It accelerates the aging or deformation of steering mechanism components, resulting in vehicle deviation and uneven tire wear; 3. It causes the damping rubber in the suspension system to age, leading to play at the connection points of the suspension's swing arms and links, with greater play causing more severe wear on the suspension system.
