The tire for use in winter has a tread made up of blocks (4) separated by peripheral grooves (5). Wave-shaped incisions (7), starting at the peripheral grooves, run part of the way across the blocks, their amplitude decreasing in the direction away from th...

The tire for use in winter has peripheral treads made up of blocks separated by large incisions (7, 7a, 7b) from opposite edges of the tread, forming a meandering configuration. Smaller incisions (8a, 8b) at right angles to the larger ones, project in oppo...

A pneumatic tire for ice-bound or snow-covered roads, which has fine grooves formed in a tread surface, thereby improving brake and drive performance on ice-bound roads in early periods of wear. This pneumatic tire for ice-bound or snow-covered roads has i...

The tire has a running strip profile divided by longitudinal grooves (2) and angled grooves (3, 4) into separate profile blocks (5, 6, 7, 8, 9). These have fine cuts (10, 11) parallel to each other in a wave form, forming profile block elements. At least t...

Raised blocks(3) of the tread pattern incorporate a pattern of cuts(6) in their surfaces. The pattern comprises a surface filling curve which makes non contact with itself along its path in a block.

A pneumatic tire comprises a tread portion comprising tread elements each provided with a sipe (4), the sipe (4) having an open top end and a bottom, and in a range from the open top to a certain depth, a configuration of the sipe in a plane parallel with ...

The tire running surface comprises cutouts which form a zigzag or wavy tread pattern and incorporate the bounding surfaces (3) of adjacent pointed body elements whose orientation alternates from cutout to cutout (4) which adjoin one another without a seam.

The invention relates to pattern blocks in the tread of a vehicle tyre, the tread comprising the tread layer (20) on the tyre carcass (25) and on that pattern blocks (1) separated from each other by wider grooves (21). At least part of these pattern blocks...
