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 .
