Mercedes GP boss Ross Brawn says he expects teams to be able to test the 2011 tires before the current season is over. He adds, however, that it is important the tests are carried out without the need to rebuild their testing teams following the introduction of the testing ban, which forced teams to dismantle them.
"There has got to be some testing with the new tire supplier, whoever it is, so I think late summer and early winter there will be some tests organized with the new tire supplier," said Brawn. "But again, we must try and accommodate that within the teams we have. We can't afford to go out and start rebuilding test teams again."
Brawn also said the 2011 tires are likely to be very similar to the ones supplied by Bridgestone now.
"The teams have together produced a technical specification of the tire we want," he said. "So there is a document that we have all contributed to which is a broad spec of the sort of tire that we want which means there is a single directive to the new tire supplier of the type of tire that is needed. That means we can continue with the development of our cars. Our cars are being designed around the current tires because we have no other information.
"So, I think everybody wants a tire to come in that has similar construction characteristics to the current tire. Whether the compounds are quite the same is another matter."
Teams are yet to decide who will be Formula 1's tire supplier next year, and an expected deal with Pirelli did not materialize during last weekend's Turkish Grand Prix. Michelin representatives flew to Istanbul to talk to the teams and make it clear it was still interested in the deal.
Team boss Peter Sauber stressed that, whichever manufacturer is chosen, an agreement must be reached soon.
"I hope we have a solution before Canada," Sauber said. "It is not an easy situation this tire situation, but it is important we have a tire supplier for the next season and I think it is important to have a sole supplier tire."
Renault team principal Eric Boullier said the French car maker would prefer Michelin, but made it clear that the F1 team would be happy with either supplier.
"Let's say historically Renault could prefer Michelin because they are both French companies, but I don't think there is a preference for the Renault F1 team," said Boullier. "It is clearly the best offer or the best package for F1 in this paddock that would suit us, now it is up to them to decide if they want to step in the next week. We have to plan our development for next year and we need wind tunnel tires."
