They are not supposed to make tyres that keep the pace and then suddenly explode.

Pirelli has been the tyre supplier for 10 years now and they still suck as bad as in the beginning. They still suddenly fall of the clip without much warning.

Apparantly they just can't make the tyres formula one demands.
Yes , they are .

Bottas was complaining for a number of laps of vibrations , and you could see the graining very clearly on his and a number of others tires .
This was clearly a sign they were in need of changing .
It was not sudden at all , except for the final moment of deflation .

Imagine trying to predict how long a given tire will last .
First , you've got , say , a Williams car and a Merc works car .
Are they going to use those tires at the same rate ?
Add in the drivers , who have their different styles of driving , and you may have seemingly identical cars using the skins at very different rates .
Then there's different set-ups for differing strategies , and it all makes for and almost impossible task to predict longevity .

There are so many variables involved , you can bet the farm that nobody is taking a forty lap predicted life as gospel , but rather as a very rough estimate .
They will last that long , without abuse .
Abuse them , and they will pop .
