Sao Paulo: Formula One teams and Pirelli are left scrambling to find a solution to test the new 2014 tyres after rain scrapped their plans at the Brazilian Grand Prix.
Pirelli brought the prototype tyres to Brazil this weekend but teams were not able to test them because it rained during both practice sessions at Interlagos on Friday.
"I think whatever flows now has to be fair for all the teams. We're in a very delicate position," Mercedes team principal Ross Brawn said. "We all want to help Pirelli provide the best tyre they can next year but it would be unfortunate if one team had the benefit of running a tyre to the exclusion of all the other teams."
