CrossFires Dual tire equalization system? Pros, cons?

[Gregory OConnor]

What happens to the air press in the good tire when the other tire
goes flat?

I just bought a air chuck at Nappa that will clip on the stem and
hold the valve down to air up. Most of the clip ons require you to
remove the valve guts and the chuck does not self close when removed.
