I read some of the NG messages about Tufo Liquid Tire Sealant going all
the way back to 1996.
I just bought a classic old bike equipped with old sewups. I was curious
about the stuff so I tried some on these tires since they're probably
throw aways any way and it's a good chance to test the sealant.
The rear tire had a slow leak and the front wouldn't hold air for more
than a few minutes. I tried the rear one first. I followed the instruction
and put in about 1/3 of the 50 ml container. So far it's been holding 100
PSI for 2 days.
Last night I tried the front tire. It started leaking some of the sealant
out of a 1 mm cut in the thread. I pulled out about a .3 mm piece of
stone, maybe a piece of flint. The bike came from Colorado. Hey Jobst take
note!
I also removed 2 goathead thorn remnants in the tread plus I found about
4-5 other round little goathead holes. After a few minutes the 1 mm cut
stop leaking. I took it back up to 100 PSI and 12 hours latter it seems to
be still holding air OK.
I suspect that the latex sealant leaks out of the punctures in the tube
and cements the tube to the casing at those points.
