    Usually the only time that happens is if you don't have enough air in your tires.
    I usually keep the recommended plus 10 but I'm a heavy rider, never had a pinch flat. YET
    knock wood!!

    Wow, what tires are you using?
    I've had years of great luck with conti's

    How much do you weigh? The amount of pressure needed to prevent pinch flats is based on the tire width and your weight. I don't think it really matters the brand of tire.

    I'm about 165 lbs and pump my Mich PR2's 23mm rear to about 105-108 PSI and front about 95-98 PSI and never pinch flat. The only one I've had in the past couple of years was when I forgot to pump up my tires for 2 or 3 days. I have no idea what the pressure was at that point though.

    You will not have pinch flats if you have sufficient pressure for your tire size and weight. This is Michelin's suggestions. It could be that your pressure gauge is defective (this would not be unusual).

    If you're getting repeated flats, it's likely that you haven't eliminated the problem that caused one of the first flats (the first rule of flat repair).

    As for tires, I really like the Conti GP 4000s.
    As others have said, pinch flats don't usually have anything to do with brand of tire, but to size and rider weight.
    I'm 180 and run my GP 4000s at 110psi and never have a pinch flat.
    I do check my tires and air-up before my ride since tires do lose a little pressure over night. This can mount up if you don't check your tire pressure for days.
    Good Luck. Multiple flats certainly suck!

    I run Conti GP 4000 on the road at about 100psi. Never a problem.
    For my dirt tires I have Ritchey Speedmax Pro at 75psi.
    They both ride beautiful and never an issue with pinch flats.
    The only pinch flats I had were with Michelin Mud 2 on a very rough road at very low pressure.

    check the insides of the tire casement for glass or debris that has worked its way through the tread.

    I like conti gp 4000 tires (black with the chili compound). I also use latex tubes. I have to pump them daily, but the ride is nicer and they're less prone to pinch flats.

    Do you pump up your tires before every ride? You should if you keep getting pinch flats, which are usually caused by under-inflation. Also try 700 x 25 tires, which are more flat resistant and durable and comfortable. I use Conti GP 4000s in 25 and never get flats of any kind.

    As others stated, your problem might be your tire or rim. Check the tire casing very carefully to make sure there is no imbedded glass or wire. Turn the tire inside out. Run your hand along the inside. Whenever I have gotten repeated flats on a particular tire, that has been the problem. Usually it's a small wire that is barely visible.

    Tire selection also has an effect on pinch flats, i use bontrager hardcase and haven't had a flat for over 6 months. I weigh 80kgs and run 23s at 90psi (sometimes as low as 80) and ride about 440km a week. Another great plus is that these tires still show little to no wear after over 7000km!!

    Operator error also possible.

    Pinch flats are also caused by improperly mounted tires. A part of the tube is under the bead rather than inside the tire and that's where the pinch flat occurs. Check both sides of the tire all the way around before inflating by pushing the tire away from the rim and making certain you don't see any part of the tube.

    don't slam into potholes, and make sure your tires have enough pressure

    I run my tires at 120 psi sometimes 125...
    problem solved just add more air!!

    And of course, you can always switch to tubies and never see another pinch flat again.

    they do have other drawbacks however ;-)


    It only hurts if you think.

    Can you safely put more pressure in tires than what is recommended by the manufacturer?

    Another possibility which happened to me was I had a small thorn stuck in my tire which was causing my tubes to slow-leak when riding. even though I always pumped up the tires to the correct PSI before each ride, the pressure would leak down through the course of riding until it lot low enough it was susceptilbe to pinch-flats.

    Since I thought the problem was due to pinch flats, and not punctures, I didn't identify it until I had multiple flats in a short time due. The proximate cause of the flat was usually something like hitting a small rock while riding at high speed etc. but the tire was susceptible to pinching in the first place due to the slow leaks.

    My weight fluctuates between 185 lbs and 200lbs, and I don't think I've EVER had a true pinch flat, even at 90-100psi. For debis flats, the best lighter weight tire I've used is Conti GP4000. Or go a little heavier and use the Gatorskins. I've flatted way more on Mich's, and I was always filling nicks and cuts wth shoe goo.
    It ain't rocket surgery. Buy everything on sale, pedal when you have too, coast when you can, and get home in one piece. Keep going forward - there is no reverse.

    No where near enough information to answer this question

    How much more pressure?
    What size tire?
    What kind of riding?
    How heavy is the rider?
    Etc,
    Etc,
    Etc,...

    Hint: If you want to get useful answers to this, start a thread with an informative title, instead of appending it to the end of an old thread on a tangentially-related topic. Further hint: put it in the wheels and tires forum.

    The answer is yes; there is a safety margin in those recommendations. However, there's rarely a good reason to do that. If you need that much pressure to prevent pinch flats, you probably should be using bigger tires.

    +1. Not to mention they're a lot more comfortable.

    I could.

    But I wouldn't want to. Most tires are already going to ride pretty harshly at max. pressure. As others have said - if it's an issue for you, consider a bigger tire. Also if it's an issue for you, the weight of a bigger tire really isn't.

    I like my Bontrager RaceLite Hard Case tires. Great for distance training.

    I really like the Maxxis Refuse. My only problem is they only come in 23 and 25 and I wanted to try something wider for a winter/rain/gravel bike.
