Pirelli reveal tyre compound allocations for Austria

Pirelli have confirmed their three softest tyre compounds will be made available for this year's Grand Prix at Spielberg, Austria.

The selection therefore consists of the yellow-marked softs, red-mark supersofts and purple-marked ultrasofts - the third time this season, after Monaco and Canada, that teams and drivers will be able to choose from the three softest options in Pirelli's range.

Under the new-for-2016 rules, teams must have a set of softs and a set of supersofts available for the race, and must use at least one of them.

Each driver will also have to save one set of ultrasofts for the Q3 qualifying session. This set will be given back to Pirelli after Q3 for those who qualify in the top 10, but the remaining drivers will keep it for the race.

The teams are free to choose the 10 remaining sets permitted from the three available compounds, making up 13 sets in total for the weekend.

While the ultrasoft has not yet been used on a Grand Prix weekend, it is due to make its debut in Monaco on May 26-29.

The 2016 tyre choices so far:

Australia - supersoft, soft, medium
Bahrain - supersoft, soft, medium China - supersoft, soft, medium
Russia - supersoft, soft, medium
Spain - hard, medium, soft
Monaco - ultrasoft, supersoft, soft
Canada - ultrasoft, supersoft, soft
Europe - supersoft, soft, medium
Austria - ultrasoft, supersoft, soft
