A vehicle tire includes a tread provided with a tread pattern, which is made up of circumferentially arranged design units having a plurality of pitch lengths Pi (i=l to j) including a minimum pitch length Pl and a maximum pitch length Pj. Each of the design units has at least one groove with side walls each having an inclination angle .alpha.i in a cross section parallel to the tire equator, and the inclination angle .alpha.1 in the design unit having the minimum pitch length P1 is less than the inclination angle .alpha.j in the design unit having the maximum pitch length Pj, whereby the rigidity difference between the design units having different pitch lengths is decreased. Preferably, the angle .alpha.i in a design unit having a pitch length Pi is not more than the angle .alpha.i+1 in a design unit having the next longer pitch length Pi+1.
