Racing Ralph 2.35x29 on 19mm rim OK?

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...

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?
