When should you check the pressure in tires of a passenger car?
aBefore the beginning of a journey.
bAfter finishing driving.
cAt least 24 hours before the planned journey.
Why?
Check tyre pressure immediately before the journey, while the tyres are cold, following the manufacturer's recommendations. Driving heats the tyres and raises the pressure, making it harder to compare with the recommended cold tyre pressure. There is no requirement to check at least a day beforehand; what matters is the pressure when you set off.
