DON'T RAISE YOUR TIRE PRESSURE!
Set your pressure while the tires are cold. As they warm up, expansion will find the right pressure.
Set the pressure cold.
I ran extended high speed on the Autobahn this summer. I ran hours at a time in excess of 110 MPH. I did it on tires that were inflated cold and were H speed rated. They worked great.
Don't overinflate for high speed! This is a safety thing.
