WebHi Dennis. Each revolution, the bike travels the distance equal to the circumference of the tire (unless you are skidding!) Bike tires are usually measured using the diameter though. To calculate the circumference, you can just multiply the diameter by π, which is about 3.142. That gives you the distance for each revolution. WebJul 30, 2015 · For example, if you have 26-inch tall tires with a 3.55 gear, and you want to go to 28-inch tall tires. To calculate the effective drive ratio of the new tires, multiply the diameters together, then multiply that figure by the gear ratio as follows: 26/28 = .92857142857. .92857142857 x 3.55 = 3.2964 or 3.30.
