Considering most of them were left fronts (Kyvat's was right rear) I'm going to have a guess and say it's from there running through that dirt patch on the corner as they come onto hangar straight. Probably a sharp edge to the asphalt there.

My thoughts exactly. Seems like everyone from Lewis to Giovinazzi was dipping at least half the LF tyre on the grass there every other lap, thus cutting the tyre running over where the edge of the tarmac meets the grass.

Maybe it was the extinction rebellion people that were in the crowd.

Threw some tacks on the grass when they were pretending to be marshalls.

Extend the astro turf an extra 5 meters after the curb please. That is just unacceptable that the tyres are being cut from running off the edge of the curb. Totally unacceptable and poor form Pirelli.

I realised this morning that the result of this race - long-time leader having a mechanical failure on the last lap and not quite being caught by the other guy - is the result of the 1997 Hungarian GP that we didn't get.

A couple of early crashes, a long stretch of boredom and those most exciting last lap in years

It's Indy 2011

Without the feel-good winner, though.

Or, and here's a novel idea, stay on the track and don't go over the edge of the kerb.

Pirelli said when they returned, they will make tyres for show didnt they. So if they cant make a tyre last 40laps then its not for them to suppy in F1. Im not complaining, just saying.
In 2005 i remember a tyre had to last whole race distance made by Bridgestone and Michelin. And they did it without problems.
Sure some teams had some problems with it but eventually they did it that season.
So if they dont know how to make a tyre last 50-60 laps ask Michelin or Bridgestone

This is one of F1's modern paradoxes tbh.

They can provide tyres that are hard enough to not be risky, but teams will just run the whole race with them and complain about them being too hard to get heat into.

They can provide tyres that are fast and wear enough to put some randomness into the races, but teams will push them to their physical limits and they will occasionally go bang, making the teams complain that they are too fragile.
