I'm not sure if it was from the jump on pingu (little ramp jump) or from corkscrew but when I arrived at the Badden between pingu and pangor I noticed my tubeless tire had lost and regained bead as there was latex squirts on various spots on my tire casing!!! I noticed that after pangor before empress more of the same and the tire was a little bit flatter - not flat mind you but less air than it had originally.
This makes sense as this is the reason people get pinch flats (the temp. unbeading). The bigger question is - will I flat without knowing it due to small repeated unseatings during a ride causing air to be lost? After X runs on Whistler would I have a flat tire - or if I'm aware of it, would I need to be adding air after so many runs?
Well onto more testing….. only time will tell. **
This is a common finding and is somewhat tire, rim and pressure dependent. If you run any combination of too fat a tire relative to too thin a rim or too low air pressure (particularly if the ground is rocky or you a doing a lot of drops), you may experience this "burping" of air. The tire bead will unseat very momentarily and will reseat. This is much more common with the Stans setup because of the lack of rubber between the bead and the rim. Probably just have to run slightly higher pressure and your problem will be solved. A wide rim will usually prevent this problem even at very low air pressures (ie. less than 20lbs.).
