Tyre for vehicle wheels, comprising a tread band divided by an equatorial plane (X) of said tyre into an outer tread band region , intended to face the outside of said vehicle when the tyre is mounted on said vehicle, and an inner tread band region , which is axially opposite said outer region, wherein on said tread band there are formed: - a pair of shoulder regions that are axially opposite one another; - at least a first circumferential rib interposed between said pair of shoulder regions and delimited by a first pair of circumferential grooves ; - a plurality of first blind recesses , which are formed in said first circumferential rib and have a first longitudinal extension, - a plurality of second blind recesses , which are formed in said first circumferential rib and have a second longitudinal extension that is smaller than said first longitudinal extension, - at least a second circumferential rib interposed between said pair of shoulder regions and delimited by a second pair of circumferential grooves , said second pair of circumferential grooves being separate from, or partially coinciding with, said first pair of circumferential grooves ; - a plurality of through-recesses , which are formed in said second circumferential rib and extend between the circumferential grooves of said second pair of circumferential grooves, and wherein: - said at least one first circumferential rib comprises an outer circumferential rib , which is formed on said outer tread band region and is delimited by a first outer circumferential groove and by a second outer circumferential groove which form said first pair of circumferential grooves; and - said first blind recesses comprise a first portion , substantially rectilinear, which extends from said first outer circumferential groove with a first inclination with respect to a circumferential direction of said tread band, and a second portion , substantially rectilinear, which is connected to said first portion and has a second inclination with respect to said circumferential direction that is smaller than said first inclination. - a pair of shoulder regions that are axially opposite one another; - at least a first circumferential rib interposed between said pair of shoulder regions and delimited by a first pair of circumferential grooves ; - a plurality of first blind recesses , which are formed in said first circumferential rib and have a first longitudinal extension, - a plurality of second blind recesses , which are formed in said first circumferential rib and have a second longitudinal extension that is smaller than said first longitudinal extension, - at least a second circumferential rib interposed between said pair of shoulder regions and delimited by a second pair of circumferential grooves , said second pair of circumferential grooves being separate from, or partially coinciding with, said first pair of circumferential grooves ; - a plurality of through-recesses , which are formed in said second circumferential rib and extend between the circumferential grooves of said second pair of circumferential grooves, - said at least one first circumferential rib comprises an outer circumferential rib , which is formed on said outer tread band region and is delimited by a first outer circumferential groove and by a second outer circumferential groove which form said first pair of circumferential grooves; and - said first blind recesses comprise a first portion , substantially rectilinear, which extends from said first outer circumferential groove with a first inclination with respect to a circumferential direction of said tread band, and a second portion , substantially rectilinear, which is connected to said first portion and has a second inclination with respect to said circumferential direction that is smaller than said first inclination. <EOS>
