The bias in this post is incredible. Pirelli said 40 laps, they did around 36-38 WITH safety car periods. When they say 40 laps they don't mean they will completely fail and fall apart, just that the tyre won't have any grip left and will become very slow.
This also isn't the first time we have seen multiple Pirello failures in Silverstone. Unless you run the tyre down to the carcass, it absolutely should not fail in this way unless cut by debris.
Pirellis predictions are just
that... predictions. Estimates. Not all cars put the tires under the same load and not all drivers put the tires under the same strain. Some took extra care, taking out speed in the high speed turns (Ferrari), others did not. Then there is also the strain that hitting curbs put the tires under.
It's impossible to ensure that all tires will 'survive' N
number of laps without knowing exactly how close to the limit every driver will be pushing their cars.
As for the failures; while debris could be a big element, the simple fact that it hit the front-left tire (the one under most load) is suspect and suggests that tire wear and fatigue could easily be just as responsible.
Here's some good info about the standing waves as a possible cause for the failures:
And for those now quick to blame Pirelli; Pirelli did design more durable tires (with a different construction) for 2020, but it was the teams that opted NOT to use them. As with any part; if you run it closer to the limit, then you are going to run a higher risk of something failing.
