Initial feedback regarding 2019 tyres 'positive' - Pirelli

Formula One teams have reacted "positively" to the 2019 tyre compounds at first glance, according to Pirelli Motorsport boss Mario Isola.

A post-season test in Abu Dhabi that lasted two days, concluding on Wednesday, gave the drivers and the teams a first chance to try out the new compounds for the 2019 season.

Charles Leclerc had his first run out in a Ferrari since the announcement that he'll be at Scuderia next season, and he finished with the quickest time over the two days - with a 1:36.450 on the new Hypersofts (AKA Compound 5).

Leclerc's new team-mate Sebastian Vettel occupied P1 on the first day of testing, but the Monegasque's topped last season's Hypersofts by four-tenths of a second.

"The teams were able to get a usueful initial read on the 2019 tyres during the two days of testing, with the entire range available, as well as all the 2018 tyres for comparison," Isola said to The Checkered Flag.

"All the teams were able to define their own run plans and mostly choose whichever tyres they wanted to test, so it's not been easy to draw any immediate conclusions on track.

"We collected a lot of data, which we are just starting to go through now, and we will need to analyse this quickly because the compounds for Australia have to be decided in a week.

"At this time, we also aim to decide the compounds for the first five races of 2019. Initial feedback from the 2019 range is positive."
