The invention relates to a commercial vehicle pneumatic tire with a tread, wherein at least the part of the tread coming into contact with the roadway consists of a sulfur-vulcanized rubber mixture.n n n To solve the conflict of objectives of abrasion, rolling resistance and wet grip at a higher level, at least the part of the tread coming into contact with the road surface consists of a rubber mixture vulcanised with sulfur, the From 90 to 50 phr (parts by weight, relative to 100 parts by weight of the total 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 From 5 to 50 phr of at least one aliphatic and / or aromatic hydrocarbon resin having a softening point (ring and ball according to ASTM E 28) of 0 to 150 ° C and an average molecular weight M n of less than 2000 g / mol and a polydispersity D = M w / M n contains from 1 to 5. |
