A vehicle is driving with low tyre pressure. How much fuel will it consume?
A)The same as with normal pressure.
B)Less than with normal pressure.
C)More than with normal pressure.Correct
* With pressure lower than indicated by the manufacturer:
- They wear more on the edges.
- They deform and heat up more.
- The risk of a blowout increases.
- Grip decreases and the risk of aquaplaning increases (the tyres cannot displace the layer of water on the road and lose grip).
- Consumption increases.
* With pressure higher than indicated by the manufacturer:
- They wear more in the centre.
- The contact area with the road and grip decrease.
- They do not absorb terrain irregularities well (they vibrate more and the suspension deteriorates).
- They wear more on the edges.
- They deform and heat up more.
