16. A pneumatic vehicle tire tread comprising:
a block row delimited on each side by first and second circumferential channels, the block row divided into profile blocks by a plurality of transverse channels that open into the first and second circumferential channels;
each transverse channel comprises two channel portions that adjoin at an obtuse angle (γ) of 100° to 160°, and
a blind channel formed in each profile block which opens into the channel portions and which is elongate in plan view and which, with the transverse channel, forms a channel combination running in a Y shape in plan view, which the blind channel has a width (bR), determined at the tread periphery, of 1.0 mm to 6.0 mm and runs at an angle (δ) of 0° to 60° with respect to the circumferential direction,
wherein the blind channel is delimited in the radial direction by a channel base, which, as seen in the longitudinal section aligned along the channel center line (mR) of the blind channel, is made up of a first base portion, which adjoins the channel base of the transverse channel and extends in the depth (tQR) of the transverse channel, a central, second base portion and a third base portion, wherein the second base portion runs at an angle (ε) of 40° to 50° with respect to the radial direction and the third base portion runs at an angle (θ) of 65° to 75° with respect to the radial direction, and wherein the third base portion adjoins the second base portion at a depth (t1), determined in the radial direction, of 50% to 85% of the depth (tQR) of the transverse channel.
