• I fully commend the @mdcc_tester method of inflating the tyres with an inner tube first.

    Both my wheels / tyres are sorted now using this approach and a normal track pump.

    it's odd cos both tyres de-mounted when I was getting the tube out and the valve stem in, but then they inflated easily, whereas before the inflation with inner tube, it was a hopeless cause.

    i guess the inflation process sufficiently shapes the tyre so it holds some air next time round.

    anyway - many thanks
