Bridgestone has confirmed the tyre specifications for the three grands prix to be held in June and early July, with the back-to-back street circuits in Montreal and Valencia unsurprisingly seeing the teams running the softest possible option.

Competitors have been informed that the supersoft and medium compounds will be taken to the Canadian and European rounds, before Bridgestone reverts to the soft specification for the British Grands Prix. The concept of leaving a compound step between the two allocated tyres for an event is retained for all of these races, with Canada and Europe getting the medium alternative and Silverstone the hard.

"The Canadian and European grands prix take place on street courses where it is important to have good grip due to the slippery nature of the track surfaces," head of motorsport tyre development Hirohide Hamashima explained, "As these tracks are not used regularly for racing, even the allocations we bring will seem too hard when used on the Friday. By race day, however, the circuit improvement and rubber laid will mean that the high grip of the super soft compound paired with the greater durability of the medium compound should provide a good combination.

"The Silverstone circuit is historically the most severe on the calendar and now the new layout makes it even more so. The new straight means a higher average speed, and there is hard braking and fierce acceleration over a lap. As always, we will be very vigilant to watch tyre temperature and wear. We expect we will see graining, even
with the hard compound, but we believe that the soft and the hard compounds should allow exciting racing."
