THE CONTRIBUTION MADE BY INTERNATIONAL RALLYING TO TYRE DESIGN AND SAFETY

Dunlop is involved in three main areas of motor sport, i.e., car racing and world land speed record attempts, international rallying, and motorcycle racing. As Formula 1 Grand Prix racing cars and land speed record cars have become more and more specialized, Dunlop has placed more emphasis on aspects of the sport where the tires have a close resemblance to standard passenger car tires, especially international rallying. Rally experience played a large part in the development of the low aspect ratio tire, and this in turn made possible the world's first commercially proven runflat car tire, the Dunlop Denovo. Rallying has also provided valuable data for evaluating breaker construction, tread compounds, and tread pattern design. The competitiveness of rallies provided the stimulus to the solution of the tire studding controversy, by developing studs which would inflict minimum damage to road surfaces. Motivated initially by Dunlop's commitments in motor sport, a research program identified road surfacing materials which will give optimum wet skidding resistance and minimum tire-road noise generation.
