Do the Conti Race King 2.2 work tubeless? any problems?
I’ve done it with non ust racing ralph’s and nobby nics and they were fairly straight forward.
Also is the 2.2 bigger or smaller size than the RR 2.25?

I used 2.2 Race King Protections with Stans for HONC, inflated ok with a CO2 cart and they held pressure well. Have left the rear one on now that the trails are (were?) drying out to see how it gets on as a summer tyre.

They have a very round profile and the shoulder knobs are about the same height as the centre tread unlike the ralph’s, and yes they do come up smaller like pretty much every conti i’ve used. Very fast rolling though.

thanks for the info, need some new race rubber as i just trashed a RR and am torn between the Race king and a vredstein blank panther
