Tire size conversion help
Hi everyone, I'm a newbie biker, and I just bought myself a new computer (even managed to install it with no problems!). I'm trying to figure out what my wheel factor is.
I have a Trek 7.2 FX and it says that I have a wheel size of 700 X 35C. The data point I need to enter is the wheel factor, or the distance in millimeters per one turn of the wheel. Per the instructions, a 700 X 32C has a wheel factor of 2155, so I'm assuming that it will be just a bit higher than that. Any help would be greatly appreciated.

Your tire diameter would be 6MM more, so that times PI would be about 19MM more.
I just "lasso" my tire with a string, and measure the string.
Even if you are off by "a few" MM, remember that's in over 2000 units. 20 "parts" off is only 1%, which is far more accurate then your car!

Thanks for your help! The exact number is 2173.8, so 2174, I had initially but in 2175, so I got pretty close!
