What is the definition of a Cold Tyre Pressure? Does it mean started in the morning or is it related to the environmental temperature?

I checked the pressure for the first time and found them to be 3.0 bar. Seems the vehicles come with more air than recommended

.

I found on a web site https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=147 that if the tyres have been in operation you should increase the air by approx 0.3 bar (4 psi).

Tyre pressure should be measured when the tyre is at the ambient temperature. (about 10 c or 50F is about right) ie before using car.Obviously the pressure within the tyre will rise if the tyres are warm/hot.

If you don't have a facility to top up your own tyre pressure (for example you need to travel for say 15 minutes) or the ambient temperature is higher (eg summer or warmer climate), then the advice given by the web site computes.
