[Closed] Minimum tyre on Stans Flow EX

I've got two bikes and 6 wheels, and the spare pair are 29er Stans Flow Ex.

They're currently set up with some fast rolling 2.2" tyres for my mtb (instead of the plus tyres), but I'm thinking I'd like to have them set up with some fast 40mm tyres for my Arkose instead. But I'm not sure if they'll work together...

Details: the Flow EX are 25.5mm internal, and say they'll take 40psi in a 2.0" tyre. I'd want to run Gravel King 38mm slicks or 40mm Schwalbe G-one speeds at about 35-40psi.

I've done a bit of research and it'll likely be fine, but some more (dis)confirmation would be good...
