What may be the consequence of insufficient air pressure in the tyres?

Correct answer
C. Deterioration of tyre grip.
Explanation
In the photo, there is the front wheel of a motor scooter with a tyre, a red rim and a disc brake. The result of tyre pressure that is too low may be poorer grip of the tyre on the road surface - answer C.
The tyre pressure should match the manufacturer's recommendations for the given tyre and load. A tyre with pressure that is too low flexes too much, its tread does not sit well on the roadway and drains water less effectively, so grip drops - especially on a wet surface and on a bend. The two-wheeler becomes heavy to handle, "floats" in curves and takes longer to brake, which is why answer A is wrong. A tyre running at pressure that is too low heats up and wears faster, and it can also slip off the rim, so its life gets shorter, not longer (answer B). You check the pressure regularly, on cold tyres, with a pressure gauge.
