On motorways, you're usually driving at higher speeds for long distances. What effect can this have on your tyres?
- A They'll be more likely to overheat and disintegrate
- B They'll have lower rolling resistance
- C They'll need less air pressure
- D They'll become very slippery
Why this is the answer
Driving at higher speeds and for longer periods, such as on motorways, can cause your tyres to overheat and disintegrate. You should make a point of checking them when you stop for a break.
Why the other answers don't fit
- B
- They'll have lower rolling resistance — Rolling resistance rises with heat rather than falling.
- C
- They'll need less air pressure — Pressures are set cold and should not be reduced for a motorway run.
- D
- They'll become very slippery — Tyres do not become slippery from speed; they overheat.
