TYRE WITH LOW ROLLING RESISTANCE

摘要

The present invention relates to a tyre, the tread of which comprises a rubber composition with a base of at least one elastomer matrix comprising more than 50% by mass of an SBR solution which bears a silanol group at the end of the chain, a reinforcing filler having a content of between 40 and 80 phr, which reinforcing filler comprises between 40 and 80 phr of a silica, a coupling agent for coupling the silica with the SBR solution, 10 to 50 phr of a hydrocarbon resin having a Tg greater than 20°C, and 0 to less than 5 phr of a liquid plasticizer. Such a tyre exhibits a good performance compromise between rolling resistance and grip.
