Agreed on the purge. Each tire already contains one atm of air with water vapor when not pressurized. We typically pressurize tires to, let's say, 30 psi, which is roughly two atm. So, even when you pump in pure N2 with no water, there is still water in the tire. Therefore doing multiple purges would probably be required to reduce water vapor to a negligible amount to make a difference in pressure/performance.
