Pirelli motorsport director Paul Hembery says he is expecting a two or three stop strategy to be the optimum approach to this weekend's Australian Grand Prix.
Formula 1 returns this week to race around the streets of Albert Park with medium and soft tyres in use.
Last season, Kimi Raikkonen won in Australia after adopting a two stop strategy, compared to a three stop strategy used by several rivals.
"This is the most radical rules shake-up of the modern Formula 1 era, so we’ve had to create a completely different set of tyres for the brand new dynamics presented by the 2014 cars," said Hembery.
"Pre-season testing has shown just what a big challenge these new rules are for everybody, but we have worked very hard throughout last year and the winter to come up with an entirely fresh range of tyres specifically designed for these latest-generation cars, featuring new compounds and constructions that actually cut down on degradation while maintaining the same level of performance."
"As a result, we’re still expecting between two to three pit stops per car in Melbourne, although we’ll be able to make some more exact predictions after we see the cars run in free practice. The first race of the season is always unpredictable but this will be the case more than ever in 2014."
