Question

How does the proper inflation
of tyres saves fuel ?
Options
O Normal reaction decreases.
O Normal reaction increases.
O Sliding contact with the road
decreases.
O Sliding contact with the road
increases.​

Answer 1

Explanation:

When the tyre is not properly inflated the tyre is not circular therefore both sliding friction and rolling friction comes into play. So, the motion of the object consumes less fuel when the tyre is inflated and this saves more fuel. So an inflated tyre saves more fuel because the sliding friction decreases.

Answer 2

Answer:

O Sliding contact with the road decreases.
