As a complete neophyte I have a question about this point in the first post:

If when you install the tyres they don't pop into place with a track pump often the best thing to do is put an extra layer of rim tape on

I assumed this is because it increases the effective diameter of the rim bed, therefore closing the gap for air to escape. Now I have a roll of tape to potentially beef up my pre-taped rims, I realise 1 layer is only going to increase the diameter by under 0.3 mm. Which doesn't seem significant.

Or does 'put an extra layer of tape on' mean 5 layers?

(I'm at the point where I've successfully mounted one tyre fine with a CO2 inflator, track pump having failed, but the other - same tyre and same rim - seems nowhere near mounting)

Have you tried this? Did the trick for me, no faffing with tape.

Thanks! I think that trick to pre-seat the tyre might be it.

@mdcc_tester I think at least part of the problem is the tyre bead just floating around above the central rim well to start with, nowhere near the bead seat, so there is more like a 5mm gap.
