Samenvatting
Car tyres are supposed to be constructed for safe, economical, pleasant and environmentally friendly driving. Three performance measures that would quite well represent the major operational characteristics of tyres within the mentioned topics would be noise emission, wet friction and rolling resistance. Since the latter affects fuel consumption it also affects economy and exhaust emissions. These authors conducted a pilot study in 1997 with the purpose to establish relations between tyre/road noise, wet friction and rolling resistance of current car tyres. The first conclusions suggested that there is no significant conflict between friction and noise or between rolling resistance and noise. (Author/publisher).
