The Cyclocross Tire Width Crowdsource Project

Are you tired of the cyclocross tire width debate?  If so, enter your data and we'll crunch the numbers, perform the analysis, calculate the statistics, and make all the results available to contributors.  All you have to do is share your data. 

The width of cyclocross clincher tires has a lot to do with the width of the rim and little to do with the claimed width from the manufacturer.  So we will use your data to define the relationship between outer tire width and internal rim with. 

While we want to keep this as simple as possible, we have some standards to follow for the sake of accuracy.  Please follow the steps below exactly and carefully.  It will make the results better and everyone will be happy!

Things you will need: Your cyclocross tire, a suitable rim, a pump, and digital calipers.


Measuring the internal rim width: The internal width of a rim can vary so we need measurements at four locations. 
  1. Enter the model of the rim as the manufacturer would describe it.  Enter "unknown" if you don't know.
  2. Enter the approximate manufactured year.
  3. Starting with the valve stem at 12 o'clock, measure and enter the internal rim width near 12, 3, 6, and 9 o'clock in millimeters.  Enter all measurements with two decimal places (e.g., 34.21).
      

Measuring the external tire width: The tire width can vary - a lot! Age, wear, and location around the tire can affect the width. 
  1. Enter the model of the tire.  Be specific and precise!
  2. Enter the approximate manufactured year.
  3. Inflate the tire to 40psi.  Make sure the tire is well seated.
  4. Starting with the valve stem at 12 o'clock, measure and enter the tire width near 12, 3, 6, and 9 o'clock in millimeters.  Precautions: do not squeeze the tire, do not measure on mud, raised letters, tread blocks, or sprues.  Enter all measurements with two decimal places (e.g., 34.21).
  5. Select how long the tire has been inflated.
  6. Select how many miles are on the tire.
