This brings up a point that has really irked me for a while now, since I am a stickler for 30 digit accuracy with regards to my odometer reading...
What effect does the wearing of your front tire have on the circumference of that tire, and how does one calculate that wear...and thus the subsequent reduction of circumference? There must be a mathmatical formula for figuring this out on the road.
Say you have what you feel is an accurate circumference for your front tire logged into your computer. Then you ride, say, 5 miles over course asphalt. Now your circumference has been reduced, but my how much? We need to figure in the relative courseness of the asphalt, the make and model of tire, your weight, the bike's weight, the front-to-rear weight bias, and, presuably, the tire pressure you are running.
Which brings up another sticking point...how do we get accurate tire pressures within, say, 10 digit accuracy?
Anyone?
