Abstract [en]

During a lifecycle a tyre undergoes degradations due to mechanical wear and chemical ageing which affect not only durability and safety but also tyre/road noise emission and rolling resistance. This paper presents a study with the purpose to study how much tyre/road noise and rolling resistance change when car tyres are worn down from the original 8 mm tread depth to 2 mm, and when chemical ageing of the tyre rubber is simulated by exposure to heat. Six car tyres of different types were selected for the study which were worn on a wear machine in steps of 2 mm tread depth. Before, between and after these wear sessions tyre/road noise and rolling resistance were measured on two drum facilities with different surface textures, including replicas of ISO surfaces. Additionally, coast-by and CPX measurements were made on outdoor ISO test tracks. The results show that the wear and age effect was low on ISO surfaces but dramatic (noise increased with wear) on the rough-textured surface and high but opposite on an extremely smooth surface.
