I've used these on my previous rides 21mm TLR Bonty rims with zero problems with burp. But my new WTB Stryker TCS wheels are 19mm. I like to run 22-25 psi. Body weight 150, and on 4-5" FS 29ers.
Is that to much tire for that rim width?? Would it distort the profile so much as to significantly increase burp potential?
FWIW a 2.25 Ra Ra is currently working fine on my Strykers, though I have had one episode of mini-burp- spewed a spit of stans on me...

Should be fine.

I am running a 2.35 excavator on a front 19mm inner diameter WTB rim. Seems to work just fine for me, but I don't run it tubeless. After having used a smaller tire on a larger width rim I can notice that it has a little bit more lateral play, and isn't quite so stiff. This can be either a good or bad thing depending on the situation. When I replace the wheel I will be moving up to a 21mm inner diameter though.
Only thing you can really do is try it out, and tell us how it worked out for you =)

This is a schwalbe tire, from reports they run a tad bit narrow.

Thanks guys. I think I"m gonna mount my 2.35 and see.
I guess the converse question would be- at what tire width is a 19mm rim too small for one to expect to be able to run tubeless safely, even when using TLR/TCS tires and similarly beaded rims?
