There is no rim seal with a tube. Turning cant do that. No air should be lost unless you damade the tube. Unless you mean the low pressure is a problem. Then the pressure would still be whatever you set it to. And even at 5psi the tyre would not fall off the rim...
i cant tell you then - what it was - i can only think of that - low PSI - knocked it off on the sharp right turn - i though the same thing - if its not broken - it should have stayed put -
but i filled it up at home before i went back out - different chair - its still hard as rock right now the tire - nothing was done to it -
if the tube was damaged or valve etc, shouldnt it have been flat now ?
i dont like not knowing what caused it - because it can happen again then - this chair is heavy - and low PSI - i could see the tire coming off the rim on a turn leaning on it - still dosnt explain where the Air went - even low PSI - it should have been there right ?
its fine now - i can only replace the valve stem and refill it again - or just remove all the air and refill it again - not replacing nothing and have to ride around a bit - close by - till i feel its OK -
but if i have to worry about this now with this chair - isnt worth it - go to foam filled - and call it a day - just wont happen that fast with insurance -
unless i can find them cheap myself online - they want $160 a tire -
410-350 - 6 is the size knobby tire - if i can find them for $50 each maybe i just get them myself - i dont seem to find them - all tube style i find
or just wait for insurance - its a process with this chair because its my back up chair - and this is the reason i kept it as a back up - not my primary chair - and another reason i like to have my older chair ready to go as a real back up chair -
when you cant do things yourself and have to wait for tech or insurance - takes a while -
being that tire seems fine now - would you just fill it up with Air and use it as if nothing never happened ?
i cant do any work on the chair myself or my girls - so my options are leave it alone - or change the stem and try again - - while starting the process for the foam tires -
i was looking forward to using the chair that day - just once a week type of chair now - i guess i can wait in that case -
i would still like to find black knobby foam filled tires in that size - if you happen to know where - post a link -
the factory shows them as high density foam filled - 12.75 x 4 size - knobby 4 ply tire with a 440 lb load rating -
i find mostly 2 ply with lower load rating and Air also - i have spare sets here - but Air for tubes -
