You learn something new every day.
I did not know that there was such a message on the tire pressure decal. I will study it before I get in the car this evening to go home.
I would expect that you still should not exceed the maximum cold inflation pressure indicated on your tires, which is almost always 35 psi cold.
The main point that I was TRYING to make was that you should not raise your tire pressure while tires are warm. If you raise the pressure, do it with cold tires.
Have a great day,
