Tire test results from german "bike" magazine
puncture height is flattening height:
the higher the number, the better.
they test it with a hetchet which falls down from test to test which higher and higher height., for example test 1 40cm, test 2 45cm, test 50 et cetera. the shown value is the first height the tire flattens.
they test also for thorn proofness with a metal thorn. i will edit that soon too. thorn test isnt available for all tires.
class a is highest resistance, class f lowest.
the fields of use:
cc is cross country race
am is all mountain
en is enduro
RR measurement:
(bad english incoming!)
Rolling resistance: All tires are set up with 2,5 bar. Then they are set up on the testing role without load. Then they are accelerated on 20 kilometers per hour. Now the resistance is set to zero to eliminate air resistance and bearing friction. Then the wheel gets loaded with 50kg. After a short time the tire runs again with 20km/h. The difference from unloaded and loaded run results gets the rolling resistance in watt.
movements in the carcass play a larger role than the tread.
