A tyre (100) for vehicle wheels, in particular for sports vehicle wheels for rally races on soft and/or low-grip road surfaces, comprises an equatorial plane (P) and a tread band (101) having a first annular shoulder portion (Al) arranged on one side of the equatorial plane (P) and a second annular shoulder portion (A2) arranged on the axially opposite side to the first annular shoulder portion (Al) with respect to the equatorial plane (P). The first annular shoulder portion (Al) comprises a first block (110) extending mainly along a substantially circumferential direction. The second annular shoulder portion (A2) comprises a pair (140) of block portions (141a, 141b) extending mainly along a substantially axial direction. The second annular shoulder portion (A2) also comprises a transversal groove (160) arranged between the block portions (141a, 141b). The ratio between the circumferential width of the transversal groove (160), measured on any circumferential plane that intersects said pair (140) of second block portions (141a, 141b), and the circumferential width of at least one block (141a, 141b) of said pair (140) of second block portions (141a, 141b), measured on any circumferential plane that intersects said pair (140) of second block portions (141a, 141b), is greater than, or equal to, about 0.5.
