I've never had tubeless wheels before and this is probably a silly question……

I've got my ZTR Crest rims, Stans rim tape, Olympic valves and NON ust Nobby Nics.

Do I need to run a sealent as well?

yes, as the rubber on non-UST tyres tends to leak air.

It's worth running sealant even with UST, to prevent punctures, but with non-UST you'll need it for sure. Stans own seems good.

Thanks for the info.

I put brand new non UST NN's on Crests with sealent – one tyre was perfect, not a hint of sealent on the outside & one tyre had several pin holes squirting sealent all ocver the place.

i'm running that exact set up and its going great. When you first inflate you may find they go down over say an hour or two. IME its best to blow up then immediately ride as that really evenly coats the latex around the tyre's inside and seals up all the invisible micro holes that otherwise give you an effective slow puncture. Don't skimp on latex – its the key to sealing small holes without you even noticing. It also helps to seal the rim.

That guide looks really great.

Cool – Just summarised what I have found out so far about tubeless – not mega experienced myself 🙂
