Pirelli has announced the tyre compound allocations for the three Grands Prix of Canada, Europe and Great Britain, with the only change from 2011 being the selection of the soft (yellow) and medium (white) compounds for the European Grand Prix in Valencia next month.

As with last year the Italian supplier will bring the super-soft (red) and soft (yellow) compounds to Canada, and the soft (yellow) and hard (silver) compounds to Great Britain, although the compounds themselves have been altered over the winter.

Drivers will compete at this weekend's Monaco Grand Prix using the previously-announced supersoft and soft tyre compounds. It will be the supersoft's first race of the year.
