The UK’s premier GT racing series concludes with a three-hour race at the home of British motorsport this weekend. With all four class titles up for grabs, and a full grid of 38 cars, tyre supplier Pirelli will play a crucial role. Pirelli will supply the P Zero DHE to GT3 and the P Zero DHB to GT4, as well as the Cinturato WH for wet weather. In the GTC class, the Porsches will use DHD2 on the front with DHE on the rear, and the Ferrari 488 Challenge will use bespoke fitment DH tyres for this car. Jonathan Wells, Pirelli UK motorsport manager, said that Silverstone would provide a good test for tyres, as “the most aggressive circuit on this year’s calendar, with extreme levels of lateral demand on the tyres and high top-speeds.”
