Think of it this way: the air in our atmosphere is at roughly 14 psi, but the atmosphere won't pump up bike tires to 110 psi, even though there is lots more air in the atmosphere. When you connect two tires by an open tube, both will always end up with the same pressure, regardless of size. If you don't believe me, try it out.

Since the Hummer has much more volume (all the space inside the tire), there's plenty of air to go around. The trick is to work the pressure up. But since there's the weight of the body of the Hummer pushing down on the tire, voila!, instant work. That’s 110psi, meaning pounds per square inch.

I don't think the intent is to pump it up to the max on your road tires, but just to get you enough air to make it home when you have a flat. RL and Jeff,

I'm no scientist, but I would think the volume of the Hummer's tire could make up for the needed air to fill a bicycle tire. You’re right Jeff.

This wouldn't do much for a road bike that needs 110 PSI. Aren’t car tires only pumped up to 45 – 55 PSI? This wouldn’t do much for a road bike that needs 110 PSI.
