You're also going to sustain major damage on your 'Stream if you don't get stopped almost immediately. Really small units like a 16 and a 19 weigh less and just can't accommodate a dual axle, but anything longer, you're playing with fire.
This type of problem is easily solved now. Look into a Pressure Pro tire monitor system. It will let you know if any tire on your rig loses a significant amount of air while under way giving you plenty of time to pull over to determine the cause of the air loss.
I won't travel without one.......especially on the single axel 19CCD
It's the cheapest insurance against a blow-out due to air loss.
