Tyre/road noise and vibration are the main sources of road traffic noise, which is an increasingly big problem in densely populated areas. At the same time, rolling resistance, caused by the energy losses in the tyre, is a significant part of the total vehicle losses and, therefore, directly affects fuel consumption and C02 emissions. In order to reduce both noise emissions and energy consumption a good understanding of tyre/road interaction and of the influence of tyre and road properties is needed. In this paper the main tyre and road parameters that influence tyre/road noise and rolling resistance are discussed. Special emphasis is placed on tyre/road contact, since the contact forces between tyre and road are the key to a reliable prediction of tyre/road noise, rolling resistance and wear. Although tyre/road models are widely applied to the prediction of tyre/road noise and low-noise road design, the potential of these models for low-rolling resistance road design is not yet fully exploited.
