Tread pattern for vehicle tire i.e. passenger car pneumatic tire, has interconnected channel whose periphery is radially formed in outer sections of funnels, which are designed in such manner such that funnels are extended to outside

摘要

The pattern has a positive profile i.e. profile block or tread tape, comprising fine incisions (1), where width of the fine incisions are parallelly limited to each other by two fine incision walls (2, 3), which includes an empty volume (4) between the walls. The fine incision walls comprise a net-like structure of interconnected channel (5). A periphery of the interconnected channel is radially formed in outer sections of funnels (6) i.e. tread periphery, which are designed in such a manner such that funnels are radially extended to outside. An independent claim is also included for a slat metal sheet for arrangement in a tire vulcanizing mold.
