Rolling Resistance Data for selected trucks.


Denny Anspach <danspach@...>
 

Using a Reboxx rolltester, here are my findings in testing some selected trucks to determine the best wheel sets allowing the most rolls. I have only had the roll tester for 16 months, so a lot of different trucks that were converted prior that time cannot be listed, inasmuch as they were only "eyeball" tested.
The numbers given are the number of rolls observed, each movement counted no matter how small.

10 0r less: Not acceptable
10-13: Minimally acceptable.
14-20: Acceptable
21 and above: Ideal
