Pirelli is to use Friday practice for the Turkish Grand Prix this weekend to once again trial a new evolution of its hard compound tyre.

Each team will be able to use the development tyre during the two Friday sessions, with soft and hard tyres being available as team's allocation for the race weekend.

"We're looking forward to seeing our new evolution of the hard compound tyre on track in Turkey on Friday," research and development director Maurizio Boiocchi said. "At Pirelli, we don't believe in standing still so, in collaboration with the teams, we're always working on new evolutions of the tyres that we hope will benefit the sport throughout the year.

"If we see the results that we expect from this life-sized test of the new tyre, our aim will be to use it at the next race in Barcelona. This tyre will provide less degradation and so we expect it to last longer, but the warm-up time will also be a little longer and there will be less grip."

As well as its continued development work, Pirelli will also celebrate something of a home race in Istanbul, with its F1 tyres being created at a facility in Izmit, just half an hour away from the circuit.

"Turkey is one of the most important events of the year for us, as we have had our production facility at Izmit for more than 50 years now," motorsport director Paul Hembery said. "As well as hosting some very important guests this weekend, we're also looking forward to what should be a spectacular race on a stunning circuit. Istanbul Park should provide the tyres with one of their toughest tests of the year, because of the high-speed corners, abrasive and bumpy surfaces, and huge forces that act on the cars.

"The fearsome reputation of turn eight is in every way justified, and this should contribute to relatively high levels of tyre wear. I expect us to see three pit stops per car, but of course it will depend on the individual strategies that the teams choose to adopt, which have become an important feature of the races so far. While temperatures in Turkey are normally warm, the initial forecasts that we have received suggest slightly cooler conditions than usual, so I think we're all in for another very intriguing and exciting weekend."
