Pirelli and British forestry officials are studying the lessons from the invitation Greenerways Rally (run June 14) in their endeavour to reduce the ecological and economic cost of gravel roads rallying. By using the less aggressive tyres than provided for present day rallying, the aim was to reduce the damage to the surfaces of the stages, reduce the displacement of gravel and therefore the need to acquire replacement gravel from faraway quarries. There were many other knock-on effects.
Firstly spectators said the reduction of lateral traction meant that cars were more spectacular and speeds were reduced, though not by the amount imagined.A British championship official said that the speed of the cars on the rally (Group N cars) was reduced only by 1 second per mile (0.6sec /km) though on actual events this might be as must as 2 seconds per mile. Many different parties, such as safety experts, are interested to know where this leads, considering the obligation to use control tyres on world championship rallies, and organisers and competitors hoping this endeavour will lead to reduced charges for using roads.
Championship tyre manager Mario Isola mentioned that Pirelli is following with interest the performance of the eco-friendly tyres on the Greenerways Rally in Britain. “The benefit of these experiments can be useful for all gravel rallying, including the WRC. These tests were carried out on tyres prepared for Group N use. Obviously it would take a lot of work to prepare a new generation of tyres suitable for World Rally Cars, but we will look carefully to see if we can prepare eco-friendly tyres when the championship is run for future Super 2000 World Rally Cars".
