The diameter is 29" as the name suggests. To find the circumference, take diameter x Pi.
about 91.1 inches
If you want to set up a bike computer, better do a roll out test.
The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
The inflation pressure is on the sidewall of the tire.
The circumference of a 29-inch pizza is 91.11 inches.
Bicycles have pretty standard tire sizes from 16, 18, 20, 24, 26, 29 inch. There may be some special sizes out there. 26 is pretty standard for adult bikes.
29 psi
Circumference = 29*pi inches
The circumference of a circle if the radius is 29 is about 182.21
The diameter of a circle with a circumference of 29 feet is about: 9.231 feet.
Circumference: 29*pi = 91.106 inches to 3 decimal places
It'd be pretty hard to decide what's the average bike wheel is. For the MTB crowd it's 26", for the road crowd it's 28", then you've got all the BMXes and kids bikes which'll be something different. Twice its radius, and entirely dependent on which size it is. Bicycle wheels come in a wide variety of sizes, usually between 12"-28".
A bicycle.
