That's a keen observation about temperature. Makes sense since the rate of diffusion through a membrane (in this case, air molecules through rubber) increases with temperature.

I wonder if the variable behavior from ball-to-ball is because you've got different brand balls? I've read Dunlop Grand Prix's take longer to re-pressurize.
