I found this on another forum. After seeing this, I don't think I'd buy maxxis high rollers. It looks like Schwalbe makes better over all tires. Below, is the results of a study done by a german magazine.
RR (rolling ressitance): lower the number the better
Flat height: higher the number, the better
Thorn : A is the best score.... F is the worst score
(the below was written by someone else...not me...)
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.
