Treadwear o ke e ?

Acho que isto te vai ajudar

http://en.wikipedia.org/wiki/Treadwear_rating

:wink:

The treadwear grade describes how long the tire manufacturer expects the tire to last. A Course Monitoring Tire (the standard tire that a test tire will be compared to) has a rating of "100". If a manufacturer assigns a treadwear rating of 200 to a new tire, they are indicating that they expect the new tire to have a useful lifespan that is 200% of the life of a Course Monitoring Tire.


Conclusão segundo percebi quanto maior for esse valor maior é a durabilidade do pneu.
