Pirelli boss Mario Isola on Monday emphasized that the Formula 1 teams will have more tire problems in the Grand Prix of Spain next weekend than is normally the case in Catalonia.

"It will be the third time that the teams will drive in Barcelona this year after the test weeks in February, but the conditions are very different. Not only because of the warmer weather, but also because of the developments the cars have been through," said Isola at the site of tire supplier Pirelli.

"This track is normally tough on tires, but with the expected high temperatures it will get much worse. The free practice will be crucial to determine the right tire strategy. This will be the most demanding Grand Prix for the tires we have ever seen. at the Circuit de Catalunya. "

Isola's statements follow a day after the Grand Prix of the 70th anniversary of Formula 1 in Great Britain, in which Mercedes again had problems with the tires. Valtteri Bottas in particular complained of blisters on his tires, while race winner Max Verstappen was not bothered by anything.

A week earlier, Mercedes did not fare much better at Silverstone. Bottas as well as teammate and World Cup leader Lewis Hamilton got a flat tire in the final phase. Hamilton was the first to cross the line, but Bottas fell outside the points.

The Grand Prix of Spain is the last race of this so-called triple header and starts on Sunday at 3.10 p.m. The Formula 1 drivers then enjoy a week of rest and resume the season on August 30 with the GP of Belgium.
