PARIS, France - The new range of Pirelli tyres will be tested by Formula 1 teams during free practice at the 2013 Canadian GP, the tyre manufacturer has said.The tyres used for the actual race in Montreal on June 9 will, however, remain in their original 2013 specification. Pirelli said the decision was taken "to provide some testing time before any new range of tyres is introduced".‘EXPERIMENTAL TYRE’"The P Zero White medium and P Zero Red supersoft for Canada will be in exactly the same specification as that which the teams started the season, with no adjustments. This new tyre will be taken to Canada as an experimental tyre for free practice, as allowed by current regulations. Each driver will receive two sets of this new medium compound for use during Friday's two sessions only."Following feedback from the teams and drivers, the new specification of tyre will then be introduced from the British GPat the end of June 2013, and will remain in place until the end of the year."Pirelli's tyres have come in for criticism this season, notably at the Spanish GP where drivers had to make four pit stops because they wore out so quickly.Drivers including McLaren’s Jensen Button and Mercedes’ Lewis Hamilton also complained that they were having to take corners slower to avoid wear and tear on Pirelli's soft fast-wearing tyres.Stay with Wheels24 for the 2013 Formula 1 season – fresh reports every day.
