Haven't Pirell also made the structure of the 2019 tyres harder compared to 2018? I guess this is where most teams struggle with this year except Mercs tank
yes exactly, Pirelli changed the structure, to cope with more downforce from the bigger wings plus the massive development race this year. they left the tread thin to avoid blistering and also at the same time make them more affected by wear, for more pitstops.
so now cars have to warm up the carcass with load, without melting the surface. one thing was that at the race last year before the tyre test, Mercedes apparently ran with extra tyre sensors, that then they were allowed to do the tyre test with! if that's true then it must've helped steer them to their high front downforce concept, that they were rather late with...
Do you have any source for this supposed increase in sidewall stiffness? Downforce was anticipated to decrease because of the 2019 aero regs with an increase of 1.5s per lap around Spain being the most common prediction. As far as I know pirelli made no mention of any construction changes or sidewall stiffness increase. Pirelli predicted a wider operating temperature range for 2019 and longer tire life closer to the limit(due to less blistering ), but they have usually been wrong about there own tires for years.
Christian Horner said they're stiffer:

"We were very good on the tyres at the end of last year," Horner said. “Obviously there’s what something like 25 percent less rubber on these tyres, and they are stiffer.
i've seen it somewhere else too. Pirelli said they'd changed the construction but not exactly what the effect was.
With the downforce, there was a lot of confusion. But they made the wings wider and also deeper, to offset the loss from cutting cascade wings and outwash, so they could change the shape of the wake to help following, supposedly, without making the cars slower. and maybe Pirelli were guessing what's actually happened, that teams have found ways of keeping a lot of their lovely outwash anyway, so the cars are faster if anything not slower and that's what we've seen isn't it
