    normal tire pressure? Where to find?

    Im wondering what the normal tire pressure is for my tires. Where would I find this out? Also, if im 310lbs, would I need to inflate OVER what it required?

    Don't over inflate, should be on the sidewalls of the tire.

    The tire will have a max pressure, but I don't think I've ever seen a "normal" pressure. It will depend on the use of the tire, and yeah, at 310lbs, you may want a little more pressure in it, but if it's a road bike with 100psi in the tires, I don't think your weight is going to matter as much as it would on say a mtb tire with only 45-50psi in it. I strictly go by feel on my mtb, meaning if it's got too much pressure in it, it will lose grip considerably, be **** on the brakes, and wash out easily in general, bounce off of obstacles, etc. If it's too low, it will be a slug to ride. Just keep in mind that whatever it says on the sidewall is the maximum to ever use period and has nothing to do with what it should be at for your specific use, just like your car tires.

    It would say on the side of the tires. I over inflate my tires about 10psi though and find it helps.

    At 326 today and 360 months ago I ride at 105-110 psi. No reason to severely over inflate.

    but this is just for 700c... and each brand/model of tire is going to be different

    I'm running 32c and still working on figuring out my idea pressure...

    Do some research its not that complicated. For a standard 700 X 25 tire you should be running at 100 - 110 but probably no more. The wider the tire the less the pressure for instance for 700 X 32 you might be at 85 - 90. For my mountain bike (26 X 2.1) I run about 35 - 40 psi on dirt and around 55 on paved roads. Tires should never be over or under inflated. Tires should also never be at the max or min limit. What works is generally somewhere inbetween. Remember when asking for information you need to provide details such as wheel size, tire width, what type of roads you ride etc. Your weight is the least of your concerns...

    Just read what it says on the side of the tyre and inflate to the maximum stated pressure.
    There have been many days when I haven't felt like riding, but there has never been a day when I was sorry I rode.

    I was breaking brokes on my bike at 350lbs, then (after getting a new wheel) I aired up the tires to the max pressure on the wheel (80lbs) and knock on wood, have been good since then.
