My first go at setting a rim up tubeless.
Superstar XX27 rim taped with two wraps of 25mm tesa 4289. Appears well stuck down, was done in the warm house to help it stick. The rim ‘well’ is fully covered but the tape doesn’t quite reach ‘wall to wall’.
Small x cut in the tape and a stans valve fitted.
Tyre fitted to rim, logos aligned with valve, bead of tyre lightly lubed with weak baby shampoo solution (as used for helitape fitting).
Tyre inflated ok with small compressor and bead seats well.
I did all this without adding sealant (stans) as I wanted to make sure the tyre would seat in case I had to revert to using a tube for initial seating of the new folded tyre.
Now air is leaking from the base of the valve stem, done up pretty snuggly, and also from the rim joint.
Are these likely to seal with sealant or do I need to go back to step one, or something else?
