Beschreibung
Zusammenfassung:	The invention relates to a tyre for vehicles, comprising a component, preferably a crown, obtained by vulcanizing a novel elastomeric composition. The elastomeric composition comprises, inter alia, at least one specific modified diene elastomeric polymer (A1) and at least one specific vulcanized silanized silica (B) having a surface area (BET), measured according to ISO 18852, of less than 190 m2/g. The novel elastomer composition according to the invention, when incorporated into a tread, imparts better wet properties to a tire while at the same time high wear resistance and tear resistance. 本发明涉及车辆用轮胎，其包括通过硫化新型弹性体组合物获得的组件，优选胎冠。所述弹性体组合物尤其包括至少一种特定的改性的二烯烃弹性体聚合物(A1)和根据ISO 18852测量的表面积(BET)低于190m2/g的至少一种具体硫化硅烷化二氧化硅(B)。本发明的新型弹性体组合物当掺入到胎面内时，赋予轮胎较好的湿性能且与此同时高的耐磨损性和耐撕裂性。
