    If you are looking for a 4 digit number to punch in it is: 2111

    That is the distance the bike travels with one tire revolution.

    Use 2105 it's a little larger then the 700 x 23c tire. Sheldon Brown says a 700 X 25c tire is 2105. It is still going to be a lot more accurate then your car.

    So one can be taller and a bit thinner then your 26 X 1.375 tire, 32 is the width in mm about 1 1/4 inches. The seven hundred X 32c is a hybrid bike tire as a way to work on the road and delicate gravel bike paths.
