European Rally Championship restricts amount of tyres per event
European Rally Championship organisers have reduced the amount of tyres available to competitors per event from the next round in Ypres onwards
Tyre use was previously unrestricted, and there was concern in the service park that leading teams were able to take six new tyres at each service halt if they wished, raising the cost of being competitive at the front of the field.
From Ypres onwards, crews can only use 20 tyres per event, with another four available for practice and qualifying when applicable.
Hand cutting of tyres to change their grip patterns has also now been prohibited.
Francois Ribeiro, motorsport chief for ERC promoter Eurosport Events, said it was important to take this action to stop costs getting out of hand.
"The ERC tyre regulations were far too expensive," he said.
"We want the ERC's open tyre competition to remain, but we had to do something to drastically cut costs for the teams.
"With six new tyres allowed after each service park, we had a situation where teams were running 36 to 42 tyres for 250 kilometres of stages, which was economic nonsense given the endurance capability of new tyres."
The new regulation will apply for the rest of the 2013 season, and will be monitored before a decision on '14 tyre rules is made.
The fifth Intercontinental Rally Challenge was the best yet, and it was Skoda UK driver Andreas Mikkelsen who emerged as champion from a tense five-way shootout at the season finale. Matt Beer reviews the season
