Bert Hoge made rolling tests for some tires (unfortunatly I have not the article and its seems not to be available online). And the curve rolling resistance vs. pressure for big apple has some kind of "knik" at 4 bars * below 4bars the rolling resistance curve decreases much with pressure increase (i.e. not linear with pressure). * above 4bars the rolling resistance does not decrease much more, and above are not more comfortable. (thats what they say on that page). dirk ============================================================ This is the Python Mailinglist //www.freelists.org/list/python Listmaster: Jürgen Mages jmages@xxxxxx To unsubscribe send an empty mail to python-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field. ============================================================
