Vehicle i.e. passenger car, pneumatic tire, has elevation continuously declining in radial extension based on maximum radial extension, when viewed in cross-sectional plane perpendicular to longitudinal extension direction of grooves

摘要

The tire has periphery grooves (5-7) with bottom having a same radial level along extension of the grooves above an extension area (21) of the grooves. The bottom is formed with a radial elevation (20) along an extension area of a junction of transverse grooves (15-18) in the grooves (5-7). The elevation continuously declines in its radial extension based on a maximum radial extension (19) in a direction of the grooves (15-18), when viewed in a cross-sectional plane perpendicular to a longitudinal extension direction of the grooves (5-7).
