Pirelli confirms F1 2019 pre-season test details, compounds for first 4 grands prix
Pirelli has confirmed that all five of its slick P Zero Formula 1 compounds will be seen in testing this year. Only three colours will be used on the slick tyres’ sidewalls to help spectators distinguish between the compounds this season – white plus Pirelli’s corporate yellow and red, in order of increasing softness. At each grand prix, the hardest compound tyre will have white sidewalls, the medium yellow, and the softest red.
