Guest agteros Posted April 16, 2011 Share Mark out a straight line of about three meter. Roll the wheel (inflated to the correct pressure), with a load, similair to when riding, on it along this line and the distance covered over one revolution will be the number to use. Easy as pie, or is that pi ? Link to comment Share on other sites More sharing options...
El Nino Posted April 16, 2011 Share The best way is to actually measure 1 full wheel revolution with yout measuring tape. Link to comment Share on other sites More sharing options...
Gataga Posted April 16, 2011 Share so theres no standard or easier way? Link to comment Share on other sites More sharing options...
El Nino Posted April 16, 2011 Share No because it also depends on the air pressure you ride with. Link to comment Share on other sites More sharing options...
Tubeless Posted April 16, 2011 Share My gps calculated mine to be 2232. Same tyre as you. Link to comment Share on other sites More sharing options...
chris_w_65 Posted April 16, 2011 Share No because it also depends on the air pressure you ride with. Also tread wear is a factor Link to comment Share on other sites More sharing options...
