摘要:
A tire tread of a vehicular tire has, in a peripheral tire direction, a plurality of tread block rows that are separated from one another by wave-shaped longitudinal grooves arranged essentially in the peripheral tire direction. The individual tread blocks within each individual tread block row are separated form one another by transverse grooves, whereby the transverse grooves are arranged such that in a left tread half as well as in a right tread half the transverse grooves are aligned with one another. The groove center lines of the transverse grooves at the outer rims of the tire tread are slanted relative to a tire axis at an angle of 3.degree. to 15.degree.. The groove center lines of the transverse grooves of the center tread block rows are slanted relative to the tire axis at an angle of 15.degree. to 50.degree. whereby the transverse grooves create a design of transversely arranged elongated S-shaped grooves.In order to provide a new tire tread which improves the concurrent properties of longevity, anti-skidding on wet surfaces, hydroplaning and noise reduction, it is suggested to provide the center tread block rows with alternating T-shaped and S-shaped tread blocks.

摘要:
A belted tire, especially for motor vehicles, has an inner carcass ply, the end portions of which extend from the inner surface of the tire, about an annular bead core, toward the outer surface of the tire. To form a connection point, the end of the outer section of the carcass ply is placed against the inwardly disposed section. The carcass ply approaches the bead core essentially tangentially, and is disposed thereabout. Between the bead core and the connection point, the two carcass ply sections extend linearly and have essentially the same length.
