older model Birdy BD-1 tubeless tires question

I'm trying to get an older Birdy BD-1 roadworthy, and have a question about the tubeless tires it has on it now. They have the word "Birdy" embossed on the sidewall, and the markings SS-98-01. They're 18x1.50 (40-355). Does anyone here happen to know the original tire manufacturer Pacific-Cycles used? Riese and Mueller say they have no idea.

Are you sure they are tubeless? Roger

This is one E-Bay listed for such a tire. https://www.ebay.com/p/Pair-Black-Sc...cle/1028573262

I am not sure they are tubeless, having never had a tubeless tire before. All I can say is that the tires had no inner tube when the bike was delivered to me, that the tires are very supple and lightweight, far more so than the Schwalbe Marathon, and that I was able to inflate the tire to 60psi using only a tiny carry-along hand pump without having to use soapy water on the rim or send a big blast of air to seat the tire on the rim. The same cannot be done with the Schwalbe, which AFAIK require a tube. So I just assumed they were tubeless. Also, it seemed from what I had read about this bike that R&M were emphasizing how light they had managed to make it. And that seemed to support the idea that these could be tubeless.

I think you need to contact the company and ask them for more information about what the bike came with but I would just put a correct tube in the tires. The fact that there was no tubes when you got the bike I suspect is not important. If the bike was not new I suspect the previous owner may have used the tubes for something else. Roger
