The perfect F1 tire can’t exist rn. I think Pirelli is operating at the limits of material sciences and literally can't make the ideal tire. We want a tire that allows the drivers to push, has predictable grip and degradation so that soft/med/hard are different, operates similarly over a wide range of temperatures, and doesn’t explode. Well some of those are at odds and some may currently be impossible. F1 drivers can destroy any tire in a few laps by pushing because the cars produce so much downforce. A tire that lets them push would need to be so stiff. That would probably ruin aspects of predictable grip/degradation. Also, I don't think a rubber exists that can both grip and operate over a wide range of temps.
The new cars may help this. The overall decrease in downforce and the consistent decrease due to the active aero should take a load off the tires. Maybe drivers will be able to push more with Pirellis new construction. But, the new tires are narrower (to reduce drag), spreading the load over a smaller contact patch. So maybe there won't be any benefits.
