Why is it not recommended to install a steering wheel cover?

Because installing a steering wheel cover can cause irreparable damage to the genuine leather steering wheel and poses certain safety hazards. Here are the detailed explanations: Damage to the genuine leather steering wheel: During daily use, constrained by the rubber fixation, the steering wheel cover cannot move extensively on the steering wheel but will have very slight displacements. These minor displacements cause friction that is fatal to the genuine leather, leaving irreparable damage to the leather steering wheel cover. Potential safety hazards: The most direct consequence of using a steering wheel cover is that it can easily cause the steering wheel to slip. Additionally, the driver's perception of the steering wheel is reduced, making it impossible to sense road conditions through the vibration of the steering wheel.
