The Italian firm has put an additional concentrate on kerbs because the Qatar GP, the place 4 drivers suffered comparable failures within the race.
Pirelli later decided that the failures resulted from drivers persistently working over and again throughout kerbs throughout lengthy stints within the race, which is why the issue hadn’t been obvious after follow.
Whereas acknowledging that the precise circumstances are completely different in Abu Dhabi, Isola famous that the kerbs on the exit of the 2 redesigned corners are of specific concern.
He intends to debate the matter with FIA race director Michael Masi on Friday night.
“They’re very comparable [to Qatar], they aren’t precisely the identical.” he mentioned. “Particularly they’re fairly aggressive on the exit of Flip 5 and Flip 9.
“They’re essentially the most aggressive. From Flip 1 to 4 they’re the identical as final 12 months, after which we’re completely different kerbs Turns 12, 13, 14, 15. The exit of flip 16 is similar because the final 12 months. So we’ve got variations in comparison with this 12 months, and they’re extra aggressive.
“There are additionally completely different kerbs on the apex of the corners, however clearly the apex is completely different. To begin with, as a result of you’ve got the unloaded tyres on the automotive which are on the apex.
“And second as a result of the drivers can handle to not run an excessive amount of on the apex, whereas I’m extra frightened in regards to the exit kerbs, particularly in Turns 5 and 9, which are essentially the most aggressive.
“We noticed from free follow each in F2 and F1 that they’re working particularly over the kerbs and the exit of Flip 9, that can be the flip with the very best velocity.
“And I am positive that in qualifying they’ll use the kerbs and possibly additionally in the course of the race if the race in the event that they push in the course of the races. So there’s this ingredient that we’ve got to contemplate.
“Clearly we’ve got a distinct state of affairs in comparison with Qatar, it is a completely different velocity, it is a completely different time they keep over the kerb, however it’s in any case, one thing we’ve got to contemplate, and we’ve got to concentrate.”

Pirelli will look at the tyres run in Friday follow for doable indicators of injury.
“The issue is that we do not have tyres with the variety of laps so that’s corresponding to the size of a stint in the course of the race,” Isola added.
“So, we will clearly additionally improve the variety of checks that we do, however someday, prefer it was in Qatar, it was not doable to foretell what occurred on the development on the tyre, as a result of it occurred after a number of laps.”
He added: “Truthfully, I am not an skilled on what is feasible to do on kerbs, if they are often changed, or if they’ll take them out or no matter, I do not know I depend on the FIA and what they’ll do.
“In order that’s why I believe that it is helpful to have a dialog and to spotlight what we’ve got discovered. I used to be additionally ready for extra data coming from working this afternoon up, after which I am positive that we will discover a resolution.
“I do not know what is feasible to do now. So clearly, what we’ve got to do is to analyse the tyres to attempt to perceive if there’s any potential space of concern, to analyse the information coming from the groups, to check that with the extent of stress that we noticed in Qatar, so we’ve got plenty of work to do now.
“And all our findings we share with the FIA, and I am positive that we will discover a good resolution that’s satisfying for each.”
