Pirelli reduces tyre pressures


In a surprise move, Pirelli has reduced tyre pressures following the opening day of the Italian GP weekend.

According to the Italian tyre manufacturer, which was called on to make a similar move last week in Belgium, the decision is the result of the higher forces on the cars compared to last year.

The original pressures were to be 23.5 psi at the front and 21.5 psi at the rear, similar to those imposed at Spa, and 2 psi up on last year. However, following yesterday's two session Pirelli given the green light to reduce the pressures to 23 psi at the front and 20.5 at the rear.

"Because of simulation that we found 100kg more force on each front tyre, and the estimated top speed is 10km/h quicker than last year," explained Pirelli's F1 racing manager Mario Isola, according to Motorsport.com.

"On the rear tyre we have estimated force of 80kg more than last year, that is the reason why we have this increase. Also last year we had 3-degree camber at the front, this year we have 3.25 to give a bit more freedom to the teams with the wear profile to avoid an excessive wear on the outside shoulder."
