Abu Dhabi, November 24, 2016 – The entire range of new P Zero tyres in wider 2017 size is on show in the Yas Marina paddock at the Abu Dhabi Grand Prix, with a first look at the new tread pattern for the Cinturato intermediate and wet tyres.

NEW SIZES.

The front tyre has grown wider by 60mm, going from 245 to 305mm. The rear tyre grows by 80mm, from 325 to 405mm. As a result, the 2017 tyres are around 25% wider than the current tyres. This applies to intermediate and full wets as well as slicks.

The new 2017 slick tyre measurements are:
•  305/670-13 at the front
•  405/670-13 at the back

The Cinturato intermediates have a diameter of 675mm, while the Cinturato full wets have a diameter of 680mm. The rim size remains unchanged at 13-inch.

TESTING. Thanks to a change in FIA sporting regulations, development of the new 2017 tyres have taken place over 10 sessions, making a combined total of 24 cumulative days of running. The test programme using individual mule cars began early August, with the latest test concluding last week at Abu Dhabi with Ferrari.

On the Tuesday after the Abu Dhabi Grand Prix (November 29) the three mule cars from Ferrari, Mercedes and Red Bull will on track together for the first time.

MULE CARS. The three teams have each provided a modified 2015 car that has been adapted according to specific technical directives from the FIA to simulate next year’s regulations, with more downforce, a wider track and wider tyres. Each car so far has completed seven days of running (as detailed in the test calendar) with the work equally split on slick tyres into all the different compounds, as well as intermediate and wet tyres.

The November 29 test day at Abu Dhabi is the eighth day of running for each of the three teams, making a cumulative total of 24 days that completes the 2016 development programme agreed by the teams, the FIA and Pirelli.

PROGRAMME. A total of five circuits have hosted the development programme, as per the details below:

RESULTS TO DATE. Pirelli is satisfied with the results obtained to date, despite the obvious difficulties that the teams faced in modifying their 2015 cars to exactly simulate the performance expected next year.

While they have delivered an increase in downforce compared to current cars, the mule cars are still some way from the real performance of the 2017 cars, which will influence the way that the compounds behave in particular. A number of these compounds, designed with a new philosophy and new materials, have already begun to meet the targeted objectives: lower degradation and greater resistance to overheating, allowing them to maintain an optimal level of grip consistently. But all these results will be validated at the start of next year in representative conditions. One complication comes from the fact that some European tests have been run in cold conditions and rain, limiting their relevance.

The development will, in any case, continue throughout 2017 to deliver the improvements that have been requested, based on data obtained during races, and supply a further evolved product in 2018.

All this has been discussed and agreed with the teams, with whom Pirelli is already working to define a new test plan for next season.

Paul Hembery, Pirelli motorsport director: “I’d like to thank all the teams that have allowed us to develop our new wider tyres for 2017, using their mule cars. We’ve made huge steps forward since trying the new tyres out for the first time at the beginning of August, and we’re pleased by the results obtained with the majority of the specifications. We know, however, that the work is just beginning. The aerodynamic progress made by next year’s cars will lower lap times by around five seconds compared to 2015, and about three seconds compared to this year. The new cars that will take to the track for the first time in February will have a downforce increase of more than 20 per cent: much more than we have seen with the mule cars. And that progress will continue throughout the whole of next season. So the next phase of our development, aimed at 2018 when the cars will be faster still, already begins in February.”
