The invention relates to a pneumatic tyre for a utility vehicle, said pneumatic tyre having a tread wherein at least part of the tread which comes into contact with the road consists of a sulphur-vulcanized rubber mixture. To solve the conflict of aims between abrasion, rolling resistance and wet grip at a higher level, at least the part of the tread which comes into contact with the road consists of a sulphur-vulcanized rubber mixture containing 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 T g of -110 to -65°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°C, and a mean molecular weight M n of less than 2000 g/mol and a polydispersity D = M w /M n of 1 to 5. |
