Hi, I've got a Giant Defy still fitted with the stock tyres and I seem to get a rear puncture every ride.
I'm a big lad at 20 stones and pump them up to 120 psi to tsystem and prevent the pinch flats I've been experiencing but it just doesn't seem to help.
Are there any specific tyres that would be better for me?

Cheers
Owen

    I'm fairly heavy and have not had pinch flats using Gatorskin tyres, 23/25 on my road bike and 28 on my winter/audax. Fit the largest that will squeeze into the frame (probably 25).

    im over 20st and run stock tyres on a claud butler 23mm, kenda i think, ive had no problems yet but i normally run them at 105- 110 if that makes a difference

    Run the biggest tyres you can fit at the lowest pressure you can to avoid pinch flats...


    Also, try to float over obstacles rather than sitting heavy on the bike, this will protect your wheels, tyres, tubes and you...

    Agree on the biggest tyre you can fit and something like a Schwalbe Durano or Conti GP4 Season are pretty tough - a 25mm tyre has a lot more volume than a 23mm and will help a lot if you suffer from impact punctures. Learning to 'unweight' your bike as you hit a pothole etc will help too i.e. just prior to hitting the obstacle, lift yourself out of the saddle.
    Make mine an Italian, with Campagnolo on the side..

    +1 for the Continental Gatorskins. Got them on my Winter Bike, excellent puncher resistance and not over heavy. A great compromise tyre.

    Another 20st rider here and use gatorskins.

    get the odd flat here and there but not what I would call regularly.

    have you checked the tyres for embedded bits of flint? They might not show up when you run your fingers round the inside of the tyre but when under pressure it may be just in enough to give you a P*******e.

    inspect every slight knick in the tyre with a stanley blade and dig out every foreign object you can.

    Forgive me if I am stating the obvious, but on the side of your tyres you will find a minimum to maximum pressure at which your tyres should be run at. Have a think about what type of pressures you are running at and note than some hand-held pumps you get might not be tough enough even to get the min stated pressure into your tyres. Half decent track/workshop pumps are available at good prices these days.
