The invention relates to an NdBR wet masterbatch comprising neodymium-catalysed polybutadienes having a high proportion of cis-1,4 units of > 95% and a low proportion of 1,2-vinyl content of < 1%, with narrow polydispersity of less than 3, with a Mooney viscosity (ML1+4100 DEG C) between 30 and 90 MU, with a high linearity index (ratio of solution viscosity to Mooney viscosity) of 3 to 10 m Pas/MU and with a Mooney relaxation after 30 seconds of 2 to 12%, the latter being prepared by means of solution polymerization, at least one carbon black, the carbon black having an iodine absorption number (ION) between 85 and 210 mg/g, measured to ASTM D1510-1304, and an oil absorption number (OAN) between 75 and 150 ml/100g, measured to ASTM D2414, and an oil.
