The new tyres are 25% wider than the current tyres at both the front and rear: part of a package of measures being introduced to make next year's cars notably faster. In 2017, the slick tyre sizes will be 305/670-13 (front) and 405/670-13 (rear).
Intermediate’s diameter will be 675mm. Full wet diameter will be 680mm.
Kimi Raikkonen took the wheel for Ferrari today, with Sebastian Vettel due to take over tomorrow in their two-day test. Mercedes is at Paul Ricard for three days, with Pascal Wehrlein driving on each day.
The P Zero slick tyres are the focus for both teams during this week's two sessions. The test programme, evaluating new compounds and constructions, will then continue later this month.
111 laps were completed by Ferrari and 134 laps by Mercedes today with no issues, in conditions that remained warm and dry at both venues.
