Question

When a tire is underinflated it:

a. Can become excessively worn on the outer edges of its tread.
b. Can become excessively worn in the center part of its tread.
c. Has a greater chance of hydroplaning.
d. a. and c. are correct.

Answer 1

An underinflated tire can become excessively worn on the outer edges of its tread and has a greater chance of hydroplaning. The correct answer is d. a. and c. are correct.

Step-by-step explanation:

An underinflated tire can become excessively worn on the outer edges of its tread.

This is because when a tire is underinflated, the center of the tread does not make proper contact with the road surface, causing the edges of the tread to bear the majority of the weight and friction.

Additionally, an underinflated tire has a greater chance of hydroplaning. Hydroplaning occurs when a layer of water builds up between the road and the tire, causing a loss of traction.

Proper tire inflation helps to maintain good contact with the road surface and reduces the risk of hydroplaning.

Therefore, the correct answer is d. a. and c. are correct.
