Bridgestone Motorsport, the Official Tyre Supplier to the FIA Formula One World Championship, has completed the first group test of the exciting new 2010 season after three days at the 4.05 km Circuit Comunitat de la Valencia, in Spain.  

This was the first opportunity for teams, drivers and observers to see in action the final specification of the new narrow front Potenza F1 tyre developed by Bridgestone for this season. With a tyre size of 245/ 55R13, the new front tyre when fitted to a rim is 20mm narrower than the 2009 specification and is designed to redress the balance of the cars after grooves were removed from the tyres ahead of the 2009 season.

 Bridgestone will again have four dry tyre compounds (Hard, Medium, Soft and Super Soft) to cover the 19 race calendar, with two selected per race weekend. Two of these four compound designations of 2010 dry tyre: the Soft and Super Soft; were available for use by the teams in Valencia this week, as well as the current specification intermediate and wet weather tyres.

Seven teams attended the test, which took place between 1-3 February, with sunny conditions and moderate winds prevailing over the course of the three day test. Bridgestone’s Potenza Formula One tyres will next be seen in use in Jerez on February 10-13, where Bridgestone expects ten teams to be present, including Virgin Racing, the first of the four new F1 teams to break cover.

This will be quickly followed by another four days of testing at Jerez from February 17-20, where Lotus Racing is also expected to join the group test. Along with the intermediate and wet weather tyres, the Medium will be the main dry compound available at both these Jerez tests, with teams also able to request the Hard and Soft compounds as additional options during both weeks.
