32 tyre types currently available on the market, with sizes commonly used for trucks and busses, produced by different manufacturers and including both steered-wheel tyres and drive-wheel tyres, were investigated to determine tyre/road noise emissions, rolling resistance, and wet braking behaviour. In addition to presenting the measuring results as such, the contribution also discusses the relationships between the characteristics determined. Among the questions answered in this context is whether or not heavy-duty vehicle (HDV) tyres with low rolling resistance and/or low noise emissions have poorer wet braking characteristics. The measuring results obtained show that the proposed EU limit values for tyre/road noise emissions of HDV tyres are too high to bring about advances in the state of the art. Steps should be initiated to lower the limit values as soon as possible.
