Recently got a cross bike, and want to take the plunge into tubeless.

I dumped the stock cross tires for a more road friendly and wider 38mm Pasela Panaracers.
They are soft sided gumwall tires, and was wondering ( eventhough they are not tubeless rated ) if anyone knows if they work as tubeless tires.

I feel like i read somewhere that gumwalls don't make great tubeless tires because of the thinner sidewall casing is more prone to leaks. But if they could work in a ghetto set up with lots of sealant i'd like to convert over, if not, i'll just keep riding tubes.

They aren't designed to be run tubeless. Definitely do not run them at high pressures (>45 psi)without tubes because the bead could blow off. They may not form a great seal because the bead shape and dimensions are not intended for tubeless. You may be able to build up the rim more to get a tighter fit. I would try to see if I could make them burp before riding them. And, as you mentioned, they may bleed a lot of sealant.

There are a number of good wide tubeless options out there. These days, it seems generally not worth the hassle and unreliability to run anything but tubeless ready tires.
