When the light comes on and the air is colder around the car you can bet that the light was very close to coming on anyway. These tires do not have much volume inside so a loss of a few cubic inches of compressed air will have have more effect than the same loss of air in a larger tire at the same pressure which has more volume inside it. This is quite obvious when you note the time it takes to use the air hose on our tires to raise them one psi as compared to the time a larger tire takes to get the same one psi rise in pressure.

Driving the car may turn the light out as the air in the tire warms up but it is still requiring more air to get the tire to the correct pressure and a better wear rate.
