The pressure in the tyres must be measured before a long trip, when the tyres are cold, on average at least once a month. If measured when hot, slightly higher pressures will be obtained, because the air will expand from the heat. The pressure in the tyres is very important because correct pressure will ensure an optimal braking time and distance, ensures optimal stability in curves and a longer lifespan of the tyres. The correct pressure is not specified on the tyre, but on the door frame, next to the fuel tank, or in the car manual.
The correct answer is: A
