The present invention relates to a tire for vehicle wheels comprising a tread made with a vulcanised elastomeric compound obtained by vulcanising a vulcanisable elastomeric compound comprising (i) a composition of elastomeric polymers consisting of at least one styrene-butadiene (SBR) polymer having a Tg of between -80°C and -15°C, in amounts of from 30 to 100 phr, optionally, from 0 to 70 phr of at least one isoprene polymer (IR) having a Tg of between -80°C and -50°C, and optionally, from 0 to 50 phr of at least one butadiene polymer (BR) having a Tg of between -120°C and - 80°C, and (ii) a mixture of oil and resins consisting of at least one low Tg resin with a glass transition temperature below -10°C in an amount of from 5 to 40 phr, at least one high Tg resin with a glass transition temperature higher than 40°C in an amount of from 5 to 20 phr, and at least one oil in an amount of from 5 to 40 phr, where the weight ratio between the total amount of said low and high Tg resins and the amount of said oil is equal to or greater than 1 :1, preferably between 1.5:1 and 5:1.
