In what way does too low tyre pressure affect the safe operation of a motorcycle?
Show the correct answer
Correct answer
B. It may impair the stability of the vehicle in motion.
Explanation
In the photo you can see a close-up of a motorcycle tyre with the word "RADIAL" on its side and a brake disc. Too low tyre pressure may impair the stability of the motorcycle in motion - answer B.
The Regulation on the technical conditions of vehicles requires the tyre pressure to comply with the manufacturer's recommendations for the given tyre and vehicle load, and the Road Traffic Act requires that the vehicle does not endanger safety. An under-inflated tyre flexes at the sides, "floats" under load and responds to the handlebars with a delay; the motorcycle wobbles on the straight at higher speed, enters bends sluggishly and may develop handlebar shake. On a two-wheeler, stability is the basis of balance, so this condition is dangerous. Answer A is the opposite of the truth: a tyre with too low pressure heats up, its sides crack, and the tread wears at the edges. Answer C is a trap - the ride may seem softer, but at the cost of handling and safety. You check the pressure on cold tyres every week and before a longer trip.
