Pirelli to change tyres from Canada

Pirelli will make changes to its tyres from the Canadian Grand Prix in a bid to rein back the excessive degradation that has affected Formula 1 this year. After admitting that having four-stop races like the Spanish Grand Prix was too much, Pirelli is to change the tyre structures so they incorporate some of the characteristics from 2011 and '12.
