New Pirellis won’t race in Canada

Pirelli's modified 2013-specification rear tyres will only be used in Friday practice at next week's Canadian Grand Prix, rather than for the whole weekend as originally hoped. A Pirelli spokesperson has confirmed to AUTOSPORT that the modified rubber, which will feature a 2012-style kevlar belt rather than the steel belt used in the current race tyres, will be evaluated during practice. Each team will be given two sets of the new-specification rubber for evaluation with a view to them being used as race tyres from the British Grand Prix at the end of June onwards.
