<< Are the tri gears having this problem?>>
Or the Taildraggers; the answer to which is no, except early on when
using cheaper non-aviation inner tubes resulting in two punctures, one
during landing.
These appeared to have resulted from internal abrasion/stressing of the
inner tube (possibly some dirt in there), rather than from a projectile.
Therein should lie a lesson.
The proper inner tubes have lasted 350+ hours, although don't hold air
as well as would be expected; may try some 'Slime'-equivalent!.

I have been following this thread on flats, and I have a few
points to make, that have worked for me.
I have been flying my monowheel almost ten years off paved
runway's...My kit included the old "tundra tire" and instructions to use
low pressure,(I don't remember PSI, but the sidewalls rubbed the Landing
gear frame.) The plane taxied like it was runing in mud..
I changed that tire at about 20 hours to a 700 X 6 and 6 plys
and used 30 PSI. The plane is much easier to taxi, take off's are much
quicker, and in 800 hours I have replaced two tires that were worn out.
No flats !!!! I can't say that the air pressure is the problem, and also
I don't fly off grass, but I have not had the problems that so many of
you are having.
On another note having made the above change I also changed the
outrigger lengths, as the new tire, with higher pressure made the
original outriggers to short. Over the past ten years I have extened the
outriggers in length, to now when the plane is parked, both outriggers
touch the ground. For me ground handling is much better, and in landing
with the longer outriggers the "rocking from one outrigger to the other"
is now gone.
Also another question ? Are the flats limited to the Monowheels
??? Are are the tri gears having this problem?

Hi,
I have this happen regularly. I now just change them every
100 hours
and I never travel without my jacking block and a spare inner
tube. I
have tried inner tube talcum powder and different pressures
with out
much improvement.
The failure mode seems to be chafing on the side wall due to
running
such low pressure.
