Pirelli have opted to run different compounds at each of the two Austrian races over the next two weekends, in a bid to provide a differentiator between the events.
This weekend's Styrian Grand Prix will see Pirelli bring their mid-range tyres, the C2, C3 and C4 as the hard, medium and soft compound, while the Austrian Grand Prix will run the C3, C4 and C5 as the range. Pirelli are able to use their softest compound tyres at the Red Bull Ring, as the circuit isn't particularly challenging on tyres.
"Once again after last year Austria hosts a back-to-back race, which means that the teams have plenty of data on this track and recent experience of how to deal with its particular challenges and tactics," said Pirelli's Mario Isola.
"However, having two different tyre nominations is a first for the Red Bull Ring, so it's going to be interesting to see how the teams get to grips with the softest C5 tyres for the second race weekend – and how the new selection influences strategy in order to create different opportunities compared to the preceding Styrian Grand Prix."
