The invention relates to a pneumatic vehicle tire having a tread with at least one circumferential groove (2), which is formed to a profile depth (TP) and has a groove base (2a) and a groove flank (2b), independent webs (6) at a distance from one another in the circumferential direction are elongated in the circumferential direction and have a top surface (11) extending parallel to the tread periphery and a height (hS) of 7% to 30% of the profile depth (TP), formed on the groove base (2a), on each groove flank (2b) and along each groove flank, between consecutive webs (6) in the circumferential direction, at least one projection (7) is formed, which is located on the groove base (2a) and is elongated in the circumferential direction, one projection (7) at least partially overlapping the other projection (7) with respect to the circumferential direction, the protrusions (7) are arranged in the circumferential direction such that a groove base channel (8) remains between the protrusions (7), which groove base channel has a constant width (bRG) in the axial direction between protrusion edges (7d) formed on the protrusions (7) and extending at a constant depth (t1) and in the circumferential direction. Each web (6) is locally widened in the middle on each side by an outwardly rounded side portion (10), which is partially delimited by the top surface (11) of the web (6), where one side portion (10) is opposite the other side portion (10), and where the other side portion (10) is partially delimited by the top surface (11) of the web (6). The web (6) has, at the side portions (10), a maximum width (bS, MAX), determined in the axial direction at the level of the top surface (11), of at most 100% of the width (bRG) of the groove base channel (8).
本发明涉及一种车辆充气轮胎,该车辆充气轮胎具有带有至少一个周向沟纹(2)的胎面,该至少一个周向沟纹形成至胎纹深度(TP)并具有沟纹基部(2a)和沟纹侧面(2b),其中,沿周向方向彼此相距一定距离的独立腹板(6)沿该周向方向伸长并且具有平行于胎面周边延伸的顶表面(11)以及为该胎纹深度(TP)的7%至30%的高度(hS),形成在该沟纹基部(2a)上,其中,在每个沟纹侧面(2b)上并且沿着每个沟纹侧面、在沿该周向方向的相继的腹板(6)之间形成有至少一个突出部(7),该至少一个突出部位于该沟纹基部(2a)上且沿该周向方向伸长,其中,一个突出部(7)相对于该周向方向至少部分地与另一个突出部(7)重叠,使得在这些突出部(7)之间保留有沟纹基部通道(8),该沟纹基部通道沿轴向方向在突出部边缘(7d)之间具有恒定宽度(bRG),这些突出部边缘形成在这些突出部(7)上并以恒定深度(t1)并且沿该周向方向延伸。每个腹板(6)在中间在每一侧上通过向外倒圆的侧部部分(10)局部加宽,该侧部部分部分地由该腹板(6)的该顶表面(11)界定,其中,一个侧部部分(10)与另一个侧部部分(10)相对,并且其中,该腹板(6)在这些侧部部分(10)处具有沿该轴向方向在该顶表面(11)的水平处确定的、为该沟纹基部通道(8)的宽度(bRG)的至多100%的最大宽度(bS,MAX)。
