My Icons (alloy wheels) valve stems look very much like tube type stems, as in they are threaded full length and have a locknut against the rim. All of my tubeless bikes have the rubber type valve stem. Have you blokes with alloy wheels got the same type of stem?

Mine are the same, look like tube type, these are a newer type, the seal is only on the inside of the rim, I can't prove it easily but am confident they're tubeless valves

Something like these?

 

[Smifff]

Yes,

Ok, hadn't seen that type before.
