| 摘要 |
The invention concerns a tyre running tread consisting, at least partly, of a rubber composition based on at least: (i) a diene elastomer; (ii) more than 50 parts by weight for 100 elastomer parts (pce) of an inorganic filler as reinforcing filler; (iii) between 2 and 15 pce of a coupling agent (inorganic filler/diene elastomer); (iv) between 1 and 10 pce of a methylene acceptor; and (v) between 0.5 and 5 pce of a methylene donor. Said running tread has, after mechanical breaking in of the tyre whereto it is destined (auto-accommodation), a rigidity gradient radially increasing from the surface inwards of the running tread. The invention also concerns the use of such a running tread for making or retreading tyres. The invention further concerns tyres comprising said running tread, in particular, for snow or ice (winter tyres). |
