Traction is improved in dry and wet conditions. Of course there is always a limit.

Not at 60+ psi it isn't. What you're probably thinking of as "improved traction" is actually quicker initial response to steering input. Push a little harder and you will discover that you actually have less total grip. This is precisely why I chose a compromise pressure of 45 psi.

Valve stems rated at 50psig is good to know but then the questions remain:
how much can it hold and are there standards or differences in the the valve stems? (I know they can easily hold 85psig and some have said easily 100psig.)

I'm not quite understanding where all this concern over the valves is coming from. Bicycle tires -- including many that use the same Schrader valves as car tires -- are routinely inflated to 100+ lbs.
