CLINGING ON IN THE WET

The author discusses the developments made in tyre design during the last 15 years. He suggests that the limit of car tyre performance will be reached with further improvements during the next five years. The development of the radial tyre is reviewed. The relative merits of radial and crossply tyres are illustrated. The advantages of synthetic and high-hysteresis rubber are explained. Research leading to a better understanding of the behaviour of tyres on wet surfaces is summarised. The author discusses the influence of motor racing on the development of optimum equilibrium shapes leading to tyres of profiles free from unnecessary stress. Future developments will include tyres such as the pirelli dip experimental design which has sidewalls capable of sustaining prolonged deflated running. Likely improvements in the method of manufacture are discussed. /TRRL/
