Bridgestone: Hard and medium tyres for 2008 Malaysian Grand Prix 

Bridgestone Motorsport has opted for hard and medium compound Bridgestone Potenza Formula One tyres for the upcoming Malaysian Grand Prix at Sepang’s Circuit this weekend. The Malaysian circuit offers a tough test to cars and drivers alike. From a tyre perspective it is a severe circuit. Two long straights head into tight slow speed corners meaning heavy braking, and the changes in regulations for 2008 mean that tyre locking could be more likely as ECU-controlled engine braking is not there to assist the slowing of the cars.

In addition to the two heavy braking zones, a wide range of corner types mean that the tyres are kept under heavy loads. The circuit layout is not the only aspect that is tough on tyres as the hot weather experienced here gives the tyres a harsh test too. Indeed, even when it rains in Malaysia, as it does frequently, temperatures remain high. To add to the challenge, the circuit has been resurfaced since the last Grand Prix, and the fresh tarmac could present different characteristics from those seen before.

Last year’s Malaysian Grand Prix saw the debut of the white groove marking which designates the softer of the two compound Bridgestone Potenzas at each event. Such has been the success of this marking that it continues in the 2008 season with the marking concept extended to include a marking on the extreme wet tyre.

Hirohide Hamashima, Director of Tyre Development, said: “We look forward to the second race of the season in Malaysia. The Sepang circuit is one that has offered us many challenges over the years and it will be interesting to experience the new track surface. Sepang is quite severe on tyres as we have two long straights leading into low speed corners, meaning heavy braking. With no traction control or engine braking control this season, drivers will have to be very careful not to lock their brakes and damage the tyres. The heat is a major reason why we bring the two hardest compounds from our range. Mechanical tyre grip is relied upon here as teams use low levels of downforce, and this puts the focus even more on the tyres. Also, we have seen rain many times at this track so we could see our wet and extreme wet tyres in use.”
