I'm just a newbie but I have to say that I don't understand why many commentators are blaming the car rather than the driver for tire degradation.
Suppose Vettel drove with an average slip angle of 8 degrees. Then dropping down to 6 degrees would save his tires at the expense of slightly slower lap times. I don't see how car setup figured in. How can the car be setup to have less tire wear when it's driven just as aggressively?
I agree but I think its a bit more detailed than that - Vettel was tending to race quite close to the car(s) in front, especially Sutil. Driving within a second or so of the car in front is driving into their wake (the same wake that allows slipstreaming) which takes away air flow and hence downforce. This means Vettel has to compensate and turn the car more as it understeers from this. That said, when you've got Alonso right on your tail, its not exactly easy to conserve tyres but keep ahead...
We saw early on that while Raikkonen was tending to catch the leading cars pretty quick, he held back from getting within a second of them and saved his tyres. I think this was partly why he won the race and Vettel didn't.
But the cars are also part of the equation. It could be that the Red Bulls are burning up their tyres more than other teams, not through driving style but also through setup.
For an example of this, look at Mercedes last year. They were consistently burning up their tyres quicker than everyone else. Thats a fundamental problem of the car, not driving styles. You'd expect drivers of Schumachers and Rosberg's calibur to be able to adapt and not over-work the tyres.
I don't think Vettel is incapable of smart driving but I think that perhaps in that race it was a bit of both - a car hard on its tyres and a driver not really looking after them as well as he could.
There are plenty of things the teams can do to set the cars up for less tyre wear - using less camber or toe, running softer suspension settings, reducing brake bias, etc. Not to mention some cars just have an inherent design problem that can cause more or less tyre wear, as I said you had Mercedes being hard on its tyres last year (apparently the exhaust was blowing onto the tyres and over-heating them) whereas Sauber were notoriously good on their tyres.
