These tubes are easily 20% larger than the tubes in Florida (but still smaller than the tubes I saw in NJ).
I have it on good authority (from just asking refs and FTAs) that the field manual is pretty sparse on details as to HOW to use the gauge (blow up UNTIL the tube fits vs. blow up and FORCE the tube to fit vs. blow it up all the way and hey, it still fits!).
With a compliant object like an inflated inner tube, I have no doubt that a triangle on the verge of bursting could still fit into a 7" gauge...
