How would under-inflated tyres affect your vehicle?
- A The vehicle's stopping distance would increase
- B The flash rate of the vehicle's indicators would increase
- C The vehicle's gear change mechanism would become stiff
- D The vehicle's headlights would aim high
Why this is the answer
Your tyres are your only contact with the road. To prevent problems with braking and steering, keep your tyres free from defects; they must have sufficient tread depth and be correctly inflated. Correct tyre pressures help reduce the risk of skidding and provide a safer and more comfortable drive or ride.
Why the other answers don't fit
- B
- The flash rate of the vehicle's indicators would increase — A faster flash points to a failed bulb.
- C
- The vehicle's gear change mechanism would become stiff — Tyres have no connection to the gear linkage.
- D
- The vehicle's headlights would aim high — That comes from a heavy load in the back, not from soft tyres.
