Hi,

I've destroyed yet another tube (this time by braking hard and making the edge of the rim cut the valve stem) and decided to try to go tubeless. The problem is that although I do want to upgrade my rims to some 25+ mm wide ones, I would like to try it with the set I have now, which are only 18 mm wide and my front tire is a 2.35" Kenda Kadre (Komodo) and there's also a 2.1" one on the rear wheel. I don't want to change the tires because I already have another set ready to be put one after the current ones wear out.

When I tried to seat the tire by inflating it through a Schrader valve cut off an old tube, it (surprisingly) did seat quite well, even though my valve didn't seal so I have no idea about how well the tire sealed. Even my current rim tape (probably not meant for tubeless) seemed to hold up quite well (though I'll probably get some Gorilla tape anyway).

I also have a bottle of a cheap tire sealant and a pair of Caffélatex tubeless valves.

Should I expect problems with a such a wide tire on such a narrow rim with neither being "officially" tubeless compatible? The tires will be used probably at 20/24 psi, sometimes 25/30.

Do you like your front teeth? Start with a tubeless rim and a UST tire for mt biking. Anything else will be hit or miss.

At those pressures you shouldn't have a problem. I used 35mm Michelin Pilot Sport tires for years tubeless at up to 40 psi with no problems.
