Question

Tyres of heavy vehicles are broad so that
(a) friction with the ground increases.
(b) pressure on the ground increases.
(c) friction with the ground decreases.
(d) pressure on the ground decreases.

Answer 1

Tyres of heavy vehicles are broader than lighter ones, so that they can uniformly distribute their huge weight and exert less pressure on the road.

Hence, the correct answer is option D.
