Not a good idea @ Mt. Bike pressures. Especially on the front. I have
to be very careful to clean the rim/tire interface to limit the
rotation of tire/tube during braking causing the stem to angle, which
can lead to stem removal. That's a stemdectomy.

Last saturday, happened to me twice. New front wheel, and dang no rim strips,
okay, filament tape. Grab a tire, how about this Conti Vertical Pro I haven't
used in forever, should be good in the gadawful sand we've got on the trails.

Went for a short shake down ride, flatted, didn't know why, didn't care, threw
in a new tube and took off with the group. Flatted again. This time inspected
found tears at the base of the presta stems. Checked the stem hole it was
properly sized, no burrs / trash. The slick new rim with production lube and /
or cosmoline everywhere except for the brake path (I washed that with brake
cleaner) would let the smooth dried out sidewalls on that tire slide by and ruin
the tube.

Anybody have a good idea on preventing this? I'm thinking a smear of tubular
glue on the bead area of the tire, allowed to dry before mounting should be
enough once I clean that rim.

If I was mischevious I'd ask about the rolling resistance penalty of using glue.

Ron,
I've run as low as 27psi w/ very fat fr. tires (2.35"), (due to sand)
w/o out slipping the tire on the rim or getting snakebite flats. I just
have to be very careful to not allow any type of lubricant of remain
between the tire & rim.

I would be very leery of using any type of glue in the tire/ rim
interface, due to the possibility of increased difficulty of tire
removal. I clean everything (tire bead area, rim flange inside &
outside) w/ acetone. If your are unable to stop tire rotation by the
above methods, you might try more pressure, & lastly the weakest glue
you can find.
