A pneumatic vehicle tyre having a tread which has two shoulder regions (1a, 1b) and a central tread region (2) between said shoulder regions (1a, 1b), wherein spikes (4) are arranged in the profile positive (3) of the tread, which spikes run in encircling fashion over the circumference of the tread in spike lanes, and wherein the spike lanes (5B, 1,2 - n) are assigned to spike zones (10B, 1,2 - n), which likewise run in encircling fashion over the circumference of the tread, wherein at least one spike lane (5B, 1,2 - n) is arranged in each spike zone (10B, 1,2 - n), wherein a spike (4) has a spike pin with an end portion (6) which projects beyond the tread surface, wherein said end portion (6) is, in a plan view of the tread, of non-circular and elongate form and, in a greatest extent, defines a longitudinal axis (7), wherein, in the central tread region (2), there is positioned a base spike zone (10B) with a spike (4) of which the longitudinal axis (7) of the end portion (6) of the spike pin assumes an angle α of 0° to +/-7° with respect to the axial direction (aR), and wherein the base spike zone (10B) divides the tread into a right-hand tread half (8) and a left-hand tread half (9). In one tread half (8, 9), at least 2 further spike zones (101, 2 - n) with spikes (4) are arranged in addition to the base spike zone (10B), of which the longitudinal axes (7) of the end portions (6) of the spike pin assume greater angles with respect to the axial direction (aR) the further axially to the outside the spike zone (101, 2 - n) of the spike (4) is positioned, and the longitudinal axes (7) of the end portions (6) of the spike pin of the spike (4) positioned in said further spike zones (101, 2 - n) assume angles β, γ, δ in a range from +/- 5° to +/- 90° with respect to the axial direction (aR).
