• I really like the 30s.

    I put one of the 33.3mm JBs on a wheel last week (see pic!) I’ve only done one ride on that wheel but the green label 33.3s are a noticeably lighter/softer/faster(?) construction than the blue label 30s.

  • How wide do these 30mm and 33.3mm tyres come up for you?

    I’ve just fitted a 30mm Mile Muncher to a Rigida DP18 (13mm internal) and it measures just 26mm fully inflated, same as a ‘25C’ Conti Grand Prix on the same rim...

  • I think the ‘30mm’ ones measure ~27mm new on 13mm internal rims. They’ll stretch a bit probably, other Panaracers-made tyres are similar.

    On 17mm internal rims they measure 30mm.

    The 33mm tyres actually measure all of that, even on 13mm internal rims. They’re thin/soft and probably have more stretch I guess.

  • I bought some 25.5c mile munchers and stuck them on rigida dp18 rims too and they come up approx 23.5mm.

    Not what I was after.
