For testing, this means an allocation of 300 sets of tyres per team - for the entire season - with total testing mileage restricted to a maximum of 30,000km while, at a race weekend, no more than 14 sets of dry weather tyres will be permitted per driver. With
Bridgestone supplying two specifications of tyre at each round - and teams required to run both in the race - the allocation will comprise seven sets of each spec. On top of that, there will be five sets of wet weather tyres per driver and four sets of 'extreme weather' tyres.
Eight sets of dry weather tyres will be made available for the two Friday practice sessions, four of each specification, but all must be returned to Bridgestone after session two. Only one set of wet and one set of extreme tyres will be permitted per driver for the same two sessions, again to be returned if used. Another ten sets of 'slicks' - five of each spec - will be made available for Saturday morning's third practice session, with two sets - one of each spec - to be returned afterwards. Four sets of wets and three sets of 'extremes' will also be available if needed, with unused rubber from Friday permissable in the allocaton.
For qualifying and the race, each driver will have eight sets of dry tyres, made up of four sets from each specification, and at least one set of each dry spec must be used by the driver in the race, unless wet or extreme tyres are used. Contrary to expectation, Bridgestone will now be finding a way of making the different tyre specifications visually distinguishable from one another to aid viewers understanding of which cars are on which tyres.
