Pneumatic vehicle tyre having a tread with profile positives' in which there are formed through-extending sipes which run at an angle of 0° to 45° with respect to the axial direction and which run parallel to one another at least in groups and which have a width (b 1 ) of 0.4 mm to 1.2 mm, wherein the sipes are each locally widened by a channel (5, 5', 5", 5′′′) with at least one channel portion (5a 2 ) which proceeds from the tread periphery and which runs in a radial direction, and at least one channel portion (5b, 5b', 5b") which adjoins said channel portion (5a 2 ) and which emerges from the profile positive , wherein all of the channel portions (5a 1 , 5a 2 , 5b, 5b', 5b") have a circular cross section, characterized in that the channel (5, 5', 5", 5′′′) is composed of an inverted T-shaped channel region and two channel portions (5b, 5b, 5b") each emerging from the profile positive by way of a channel opening , wherein the inverted T-shaped channel region is composed of the channel portion (5a 2 ) which proceeds from the tread periphery and which runs in a radial direction and forms the longitudinal beam of the T, and a channel portion (5a 1 ) which forms the transverse beam of the T, wherein the channel portions (5a 1 , 5a 2 ) forming the longitudinal beam of the T and the transverse beam of the T have identical diameters (d 1 ) and are the narrowest channel portions (5a 1 , 5a 2 , 5b, 5b', 5b"); wherein the channel portion (5a 1 ) forming the transverse beam of the T has a length (l 1 ) which is 150% to 300% of the diameter (d 1 ) of the channel portion (5a 1 , 5a 2 ) forming the longitudinal beam of the T, or the transverse beam of the T, respectively, wherein the ends of the channel portion (5a 1 ) forming the transverse beam of the T are in each case adjoined by one of the channel portions (5b, 5b', 5b") that emerge from the profile positive by way of a channel opening and, proceeding from the channel portion (5a 1 ) forming the transverse beam of the T, widen in each case towards their channel opening . the channel (5, 5', 5", 5′′′) is composed of an inverted T-shaped channel region and two channel portions (5b, 5b, 5b") each emerging from the profile positive by way of a channel opening , wherein the inverted T-shaped channel region is composed of the channel portion (5a 2 ) which proceeds from the tread periphery and which runs in a radial direction and forms the longitudinal beam of the T, and a channel portion (5a 1 ) which forms the transverse beam of the T, wherein the channel portions (5a 1 , 5a 2 ) forming the longitudinal beam of the T and the transverse beam of the T have identical diameters (d 1 ) and are the narrowest channel portions (5a 1 , 5a 2 , 5b, 5b', 5b"); wherein the channel portion (5a 1 ) forming the transverse beam of the T has a length (l 1 ) which is 150% to 300% of the diameter (d 1 ) of the channel portion (5a 1 , 5a 2 ) forming the longitudinal beam of the T, or the transverse beam of the T, respectively, wherein the ends of the channel portion (5a 1 ) forming the transverse beam of the T are in each case adjoined by one of the channel portions (5b, 5b', 5b") that emerge from the profile positive by way of a channel opening and, proceeding from the channel portion (5a 1 ) forming the transverse beam of the T, widen in each case towards their channel opening . <EOS>
