FIELD: transport.SUBSTANCE: invention relates to automotive industry, namely, to large truck tire tread. Tire has tread 1 with absolutely new running surface 10 with at least one running path 2 confined by sidewalls located opposite each other. This running part 2 opens discretely to running surface 10 by multiple parts 21 opened outward of the tread. Note here that said open parts 21 have two ends 212 extending under running surface by channels 22 having inlets 221, 222 connected with ends 212 of said open parts 21. Said inlets 221, 222 feature mean area S. Tread is made so that every part 21 opened to sunning surface has closer 4 at every its end to close cross-section of channel inlets 221, 222 in motion and keep passage open.EFFECT: better braking performances.10 cl, 10 dwg |
