a ver bros aki le paso una explicacion de lo que es el treadware y tengo una duda? tengo entendido que para arrancones y pista es recomendable menor treadwear. si se supone que a menor treadwear es menor la duracion de la llanta en que influye que sea mejor para pista??




Treadwear
Treadwear grades typically range from 60 to over 600, in twenty-point increments. It’s important
to remember that the actual life of any tire is determined by the road surface quality, driving
habits, inflation, wheel alignment and rotation it experiences. To receive a treadwear grade, a tire
is tested under controlled conditions on a government-prescribed test course that does not
necessarily stimulate the actual application from which a given tire is designed to perform. As a
result of these test parameters, there is no reliable way to assign miles of wear to treadwear grade
points.
Treadwear ratings are determined on a 400-mile government test course covering specified
sections of public roads near San Angelo, Texas. A group of not more than four test vehicles
travels the course in a convoy so that all tires experience the same conditions. Tread groove
depths of the tires being tested are measured after each 800 miles. The same procedure is
followed for a set of control, or “course monitoring tires.” Upon completion of the 7,200-mile test
the rating results of both tests are compared, and the tires being tested are assigned a treadware
rating by the manufacturer.
The best way to use treadware ratings when selling tires is to compare one rating to another. For
instance, a tire with a treadware grade of 400 might be expected to last twice as long as a tire that
has a grade of 200.
