• First time tubeless user here. After installing tape and tire on the rim I could get the tire to seat by inflating it with a track pump. It made a few "ploing" noises and the tire holds air for like 20-30 seconds without sealant. I can hear a hissing sound from the air escaping around the valve area. Does this seem ok to you and will properly seal once the sealant is added or should I reinstall tape and valve? I just want to avoid the mess of having to reinstall after the sealant was added.

  • Have you tightened the valve with a pair of pliers, to get it really airtight?

  • You can also dab a bit of sealant around the valve's rubber plug before tightening it. No idea if it does any good though.
