Paul Hembery, the Pirelli motorsport director believes all the Formula One teams will use this week's final pre-season test in Bahrain to gather as much information as possible about the 2014 specification tyres.
Although there have been eight days of winter testing at Jerez and Sakhir already, most teams used the first two test to work on any issues they had with the new 1.6 litre turbo-powered engines that will be used this year.
Race set-up and simulation work are expected to be a major part of this week's test in Bahrain and Hembery admitted that tyre work should form a large part of that.
"We saw more work on tyres at the recent Bahrain test than there had been at the very first test in Jerez, and with teams likely to be attempting more qualifying and race simulations this week in preparation for the opening grand prix, we would expect this upward curve of tyre work to continue over the final four days in Bahrain," Hembery told crash.net.
"It's still early days, but so far we've seen both performance and durability from our latest P Zero tyres, which all feature new compounds and structures to maximise the unique power characteristics of the latest-generation cars. The contact patch is greater, to help put down the extra torque, and the working ranges are wider to reduce degradation.
"As the lap times in Bahrain have shown, we're already very close to 2013 levels of performance, despite much smaller capacity engines and a completely fresh set of technical challenges."
