    Measure the circumference of the wheel.

    Put the valve at the bottom of the wheel, mark the floor, roll the wheel until the valve is at the bottom again, mark the floor here. Measure distance between the two marks. That's the number you need to put into the computer.

    That depends on your computer though. I had to put 212 into mine.

    The little instruction book usually says what number to put in for each wheel size. If you've lost the instructions lots of the manufacturers out them on their web sites.

    Best follow redddragons original advice and measure it yourself more accurate that way.
