Abstract

Vehicular pneumatic tire having an asymmetric tread formed in relation to a circumference of a running surface and process of making vehicular pneumatic tire. The vehicular pneumatic tire includes an outside region that includes an outside shoulder block row and an outside circumferential groove, an inside region that includes an inside shoulder block row and an inside circumferential groove, and a center region that is laterally delimited by the outside circumferential groove and the inside circumferential groove. A plurality of transverse grooves are arranged within the inside shoulder block row, and the plurality of transverse grooves further are arranged to extend into the center region. No more than about one-half of the plurality of transverse grooves are arranged to at least nearly entirely traverse the center region and are oriented to form an angle to a circumferential equator line of no more than approximately 30° over at least one-third of their longitudinal extensions. The process includes forming an outside region to include an outside shoulder block row and an outside circumferential groove, forming an inside region to include an inside shoulder block row and an i…
