A pneumatic tire for a commercial vehicle with a tread, wherein at least the part of the tread which comes into contact with the road contains a sulphur-vulcanized rubber mixture. The sulphur-vulcanized rubber mixture contains 90 to 50 phr (parts by weight, based on 100 parts by weight, of all of the rubbers in the mixture) of natural rubber, 10 to 50 phr of at least one polybutadiene having a glass transition temperature Tof &#x2212;110 to &#x2212;65&#xb0; C. and 5 to 50 phr of at least one aliphatic and/or aromatic hydrocarbon resin having a softening point (ring and ball to ASTM E 28) of 0 to 150&#xb0; C., and a mean molecular weight Mof less than 2000 g/mol and a polydispersity D=M/Mof 1 to 5.

A sulfur-crosslinkable rubber mixture which, for improved abrasion characteristics with no significant deterioration in rolling resistance and in wet grip, comprises at least one functionalized diene rubber, the functionalization of which is along the polymer chain and/or at the end and enables attachment to fillers, the diene rubber having a glass transition temperature Tof &#x2212;110 to &#x2212;15&#xb0; C., at least one aliphatic and/or aromatic hydrocarbon resin with a softening point (ring and ball to ASTM E 28) of 50 to 150&#xb0; C. and a mean molecular weight Mof 200 to 2000 g/mol, and a polydispersity D=M/Mof 1 to 5, and at least one filler.
