Pirelli has selected the ultra-softs, super-softs and softs available to teams for the Singapore Grand Prix, it has been confirmed.

After the new purple-banded ultra-soft tyres made their highly-anticipated debut in Monaco last weekend, the softest compound available in F1 will be given its fourth outing of the year after also being selected for Canada and Austria.

As expected, the super-softs and softs will also be available to teams in Singapore. Both sets must be available for the race and drivers must use at least one of them in the race.

The new 2016 tyre regulations state tyre nominations for long-haul events have to be made 14 weeks in advance, whereas for European races the deadline is eight weeks in advance.
