Sagot :

Final answer:

Tire wear bars indicate tire tread depth for safe driving.


Explanation:

Tire wear bars are indicators located inside the tire grooves that show if the tire tread depth is sufficient for safe driving. When the tire's tread wears down to the level of these bars, it signifies that the tire needs to be replaced to maintain proper traction and safety on the road.
