<p>The invention concerns a running tread for a tyre comprising multiple incisions (30), each incision being delimited by two opposite main walls (21, 32), each of said walls consisting of a median surface the intersection of which with the running surface forms initially a ridge, the average width of each incision measured as the average distance between the ridges formed by the opposite main walls (31, 32) of said incision on the running surface initially is not less than 1,5 mm, each of the main walls (31, 32) including at least one blocking region co-operating with an opposite blocking region so as to block mechanically relative movements of said walls at least in the tire-road contact.</p> |
