What must be ensured about the tread wear of tires?

The correct answer is that tire tread should be evenly worn. Even tread wear is essential for several reasons: it ensures that the vehicle maintains proper traction on the road, providing stability and control, particularly in adverse weather conditions. Uniform tread depth also contributes to better handling and longer tire life, reducing the risk of blowouts and improving fuel efficiency.

When tire tread is uneven, it can indicate underlying problems such as misalignment, improper inflation, or suspension issues, which can be dangerous while driving. Additionally, uneven wear can lead to compromised contact with the road surface, increasing stopping distances and negatively impacting overall vehicle performance. For these reasons, maintaining even tread wear is a critical aspect of vehicle safety and maintenance.
