My tubeless MTB front tyre has a slow puncture.
I have pumped it up and performed a rigorous soapy bubble test. No sign of leakage.
I cannot hear any sealant inside the tyre.
The tyre is new on the wheel but has not been ridden for a few months.
Do I:
A - Buy some sealant and inject it through the valve.
B - Take the tyre off, pour in sealant and re-inflate.
C - Go on a bicycle maintenance course.
D - Go on a 'how to search more effectively on youtube' course.
Pump it up and try submerging in a bath to find the leak.
Then A.
(let air out or wear safety specs)
take out valve core & clean
put back in & tighten sensibly
then --> whitestone
Submerge it, making sure whole valve is also submerged. It probably just needs some sealant though.
A, pump up tyre, then go for a ride to slosh it about
Just out of the bath with tyre.
I could hear a 'bzzzzzzz'.
Could I see the source?
No.
I have identified the approx area and am now going back to the bubble method.
I should also have added to the above:
E - Go and buy some sealant.
Opticians
Whenever I've had this I have only ever fixed it by retaping it.
I've got one right now which I've been pretending for a week just needs a bit more shaking/sealant/riding/pixiedust.
I also forgot about option F - put a tube in.
Done in seconds rather than hours. No head scratching/ mess/ faff/ swearing/ worrying about the great unknowns of whether I would get to the end of the road without it going down again. Worked a treat. I really do wonder why I bother with tubeless.
I think tubes could really take off.
The next 10 punctures that have you preparing/fitting another tube rather than just continue to ride along with a tyre a few PSI lower will have you wondering why you bothered with tubes.
Sealant is in the tyre for a purpose and any really slow punctures will soon seal up again once you ride the tyre after it is fitted.
