Ultrasoft Pirrelli tyres to make racing debut in Canada

Pirelli will make their new, purple-marked tyre available at the Canadian Grand Prix Formula One Championship in Montreal on June.

Teams will also be using the yellow-marked soft and red-marked supersoft tyres in Montreal. As part of the new rules, in Canada every team must save at least one set of the ultrasoft for Q3. Those who qualify inside the top 10 will have to give the tyres back to Pirelli at the end of qualifying. Those who do not make the cut can keep the extra set into the race.

Teams must also have  at least two sets of softs in reserve for the race, and must use at least one of them. Teams are free to choose the remaining allocation of their tyres to take them up to the mandatory total of 13 sets for the weekend.
