Bridgestone won’t help Pirelli
They may not be competitors on the track but that doesn't mean Bridgestone will be handing over any information to Pirelli. Pirelli are set to take over from Bridgestone as F1's tire supplier next season and have already conducted their first test.
The Italian tire manufacturer spent two days at Mugello earlier this week with Nick Heidfeld using a 2009 Toyota chassis to test the tires. Pirelli already have further test scheduled and will need as much track-time as possible as they won't be getting any help from Bridgestone.
"I am sure as a supplier of GP3, Pirelli has already collected enough information for Formula One," a Bridgestone spokesman told motorsport-magazin.
