    Just pumped bike tyres with track pump..on the tyres the min is 50 and the max is 80
    Had difficulty pumping past 45 on the gauge...is this normal for newish tyres?
    Is 5 below the minimum ok?
    (btw it's hybrid bike used for leisure and short journeys)

    5 under should be ok but it probably depends on your weight - the heavier you are the more you need to put in to avoid pinch flats.

    If your track pump isn't up to it, you could try pumping them up in a garage forecourt. Hybrids can have either a Presta (narrow) or a Schrader (car tyre) valve. If it a Presta, you can still top it up in a garage by using one of these guys: link

    They're presta valves...found that out the hard way after walking all the way to the garage with the bike today! Picked up the 'beto' track pump in Argos to do the job instead..

    I'm only 8.5 stone so I wouldn't think too heavy for that pressure..

    Do new tyres take a bit more muscle to pump? Could probably push it a bit but having visualisations of tyre exploding in my face!!

    I bought a track pump in Argos once and had to throw it out - dunno what your's is like.

    My Advice?
    • Spend a couple of Euro on that adapter
    • Return the track pump to Argos and get your money back. Spend a few more Euro the next time.

    New tyres are not generally harder to pump.

    Theres probably something wrong if you can only get up to 45psi with a track pump. Most of them will get to 100psi or more fairly easily.

    That argos one actually looks decent enough too.

    Maybe check your valves, make sure they aren't sticking and the head of the pump is on properly...

    I think I was just being too cautious (had a bad experience with a guitar string once i think it's left me with some fear !) have to put my back into it a bit but could probably get 80, at 60 now which is for for me

    Not used to the while cycling process so thanks for the help guys!
