It occurred to me while I was thinking about what happens with water in the tire.
As the tire reaches 100C, the temps would stabilize at 100 until all of the water is converted to vapor even as more heat is added.
Once all the water boils off the temps will start to rise again.
So water in the tire is actually a good thing for racing, but likely drives pit crews crazy trying to get
consistent tire temps.
(I am one of them as I have taken thousands of tire temp measurements with my clip-board & tire probes :-)
Differing amounts of water would give you varying results on a day-by-day or race-by-race comparison.
And actually since water vapor is a better themal conductor than dry-air/nitrogen, the heat from the tires would move to the wheel more efficiently than just dry air or nitrogen both by convection and conduction.
