I toured on a bike with TR tubes, I could feel when the PSI dropped, so I topped them up.

but this was a minor inconvenience, let the PSI drop too far and the tire torque shifts around the rim, on the rear ,

carrying the tube with it, the hole in the rim does not move, shearing the stem from the innertube... un fixable air loss, results.


To run low PSI the company in AK selling ,mountain bikes ridden year around in Fairbanks,

recommends gluing 1 tire bead to the rim, with sew up tire glue.
