For companies such as Michelin, motorsport plays a very important role in the development of the tyres eventually sold to the public – even if they are very different from those used on the track. Involvement in motorsport has two obvious benefits; publicity and proving technological superiority. There are other benefits though; it offers an extreme training ground for skilled engineers, developing team skills and experience at the limits of tyre technology, and knowledge which cannot be gained elsewhere. Products developed for the race track will never find their way directly on to road-going vehicles. However, many elements of motorsport tyres have found their way into commercial tyre products – compounds, Kevlar and Aramid fibres – whilst rally events supply information about tread design, puncture resistance, rubber hardness and thermal resistance. Motorsport also offers a test bed for simulation procedures. Development is tried out on the virtual test bed and trial tested in the most extreme conditions imaginable. From a tyre manufacturer’s point of view motorsport is about getting a set of tyres to complete the race and cross the line in first place – the rest of the car is only a means to that end. The tyre must be designed to last for the duration of the race. It therefore can and will have a completely different set of design criteria from a road tyre, which has to undergo 25,000 miles and more of driver abuse, function in many weather and road conditions, and give warning when approaching their limits. The race tyre is designed to carry out a single race at maximum power for the duration of its working life.
