Dear Jim
Read careful my post: I like to use pressure 2,0 -
2,2 bars. 2,1 bar = 30,45 PSI. So we land with
same pressures. Pressure - low or high - is not a
reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going
to do same as Paul is doing: changeing regularly
tube. Makes me sense to change it every year (= in
my case every 50 hrs /about 50 - 100 landings. I
never can do it in 30 minutes but so what. Tube is
very cheap. For example yeasterday I spent 6 hrs
fighting with that problem with my wife and that
newspaperman. That is 18 hrs + all the extra fees
+ 400 km driving car. That must be same as buying
let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That
delicate scent is a bit embarrassing...

All monowheel drivers
Following this thread today... I have a few
commits to throw to the forum...I notice that
Europa requires very low tire pressure in their
manual....
I also noticed today that quiet a few monowheel
drivers are having flat's....I suspect that with
the low air pressure, when you land the sidewals
are flexing due to low air pressure...this is
probably "pinching the inner tube" and then the
tire goes flat....
I have always kept 32 PSI in the tire. IN 10
years, and two tires and tubes, I have never had a
flat....Yes I know I have been blessed by the good
luck god..
Thank about it with 32 P S In the tube the
sidewalls are not flexing......Just my thought's
on this matter....
