The GP2 Series uses slick Pirelli tyres in four specifications (super soft, soft, medium and hard) which are predetermined by Pirelli in advance of the race weekend.
In a change of regulations in 2012, each driver has four sets of dry-weather tyres per weekend – three of “prime” specification and one of “option” specification (in Monaco, there will be two of “prime” specification and two of “option” provided per driver). Each driver will also be provided with three sets of wet-weather tyres.
As always, teams and drivers will have to keep one fresh set of prime for the Sunday Sprint Race. However, they will be able to choose between the remaining two sets of “prime” and the one set of “option” to use either during Free Practice, Qualifying and/or the Saturday Race. The compulsory pit-stop during Race One remains in which a minimum of two tyres must be changed. This pit stop may not be carried out until the driver has completed six laps.
