De La Rosa tests the 2010 tires

Pedro De La Rosa joined the other teams yesterday at the Jerez circuit to conduct tire development tests that will be used during the 2010 season. According to the regulations that will be in place, tire warmers and refueling will be prohibited.

The McLaren driver completed 94 laps with a time 2.8 seconds off the reference time of the day, attributed to Sebastian Vettel at 1:19.055, with the Red Bull 2009 configuration.

McLaren and Bridgestone were able to gather a large amount of data before an oil pressure problem stopped the testing day 10 minutes before the end of the session.

Pedro De La Rosa stated that driving without using tire warmers is really very difficult to heat the tires and thus find the right temperature. But this is the goal for the 2010 season, which is why Bridgestone will supply different types of tires to the teams. We completed many laps today, and the work done on the tires was very positive.

The absence of tire warmers and the ban on refueling during the 2010 races means a development of more durable tires to be able to absorb the extra weight of the cars.
