Question

Quizplus · Accepted Answer

When the tire flattens significantly, more of its surface area comes in contact with the ground, which means more force is required to move the vehicle. This requires more energy and puts more strain on the engine, resulting in lower fuel efficiency. Additionally, the excess friction generates heat, which can cause the tire to wear out more quickly, and in some cases, burst.
