Pirelli have announced their new range of tyres will only be used in Friday's practice sessions at Montreal.

In the wake of the backlash triggered by the Spanish GP featuring over 80 pit-stops, F1's tyre supplier revealed their intention to produce beefed-up compounds, featuring 'elements of the structure from last year', in Canada.

However, having already been warned by the FIA that the regulations only permitted changes made for safety reasons, the Italian company has now confirmed their amended compounds will just be used in the Friday practice sessions at next week's Canadian GP.

However, Pirelli remain hopeful that their new tyres will be used in the British GP at the end of next month.
