Could try nitrogen in your tires if you experience such temperature changes man
The semis should have an increase of around 6psi from cold to hot. It isn't an issue if you know what you are doing, but I clearly misjudged the huge difference between 15 and 37 degrees ambient temperature.
I find that at a track day, once they warm up initially they stay fairly consistent across the day, just dropping a pound or two as it gets hotter. When I finally get a thermometer I'll post up some figures for the tyres, brakes etc. As an example, water boils on contact with the rim after 10 laps around wakefield, so everything is pretty hot.
