How to measure pressure in the tubes?

Will the guage read 2.5 PSI? From what I remember, it won't. Almost no "normal" guage (normal in the sense that it's commonly seen and/or used) will read that low.

It depends what gauge you use, there are low pressure gauges.

Exactly. Some gauges measure a max of, say 10 PSI. Perhaps an electronic pressure sensor, often sold as an accessory for a voltmeter, or something in the auto repair world, might be appropriate.

Anything qith a max scale of about 10 times the pressure you're trying to read will be horribly inaccurate.

To measure the pressure in a tube, connect some tubing (metal or plastic) to the inflation opening, connect that to the plastic tube and through the correct connectors to a gauge. A "T" fitting will allow inflation as necessary.

low pressure tire gages are commonly available for use with racing tires, here is a sample from a large mail order hot rod parts store.

also many older automotive vacuum test gages will read pressure up to about 10 psi (for testing mechanical fuel pumps), ask around to see who on your team has a friend/relative with some automotive tools.
