Think it's fair to take that some drivers are easier on the rubber. Sutil on Sunday for a start and Perez for examples. Button defenately, but the drivers can alter their driving styles to compensate, only have to think Lewis for that one.
That said, those who are naturally easier on thier tyres, again Button as an example, haven't quite had that available as of late, mainly due to Pirelli supplying the tyres now, and the compounds they have incorporated and the wear rates they have applied ( characteristics).

So it's negated any possible advantage a driver might have in relation to it for me, and has set a new range of parameters in relation to the tyres and getting the best out of them, for the teams. Not least the " dropping of the cliff" explanation to explain the drastic drop off in performance once the tyres start to go.


That and the fact it's a learning curve for pirelli lately, and one they've changed a few times in relation to characteristics.

But easily proven previously with other tyre manufacturers in the past with certain drivers.

2011 season has failed to achieve an optimum result in a race due to poor driver management of tyres.

Thanks for your contribution but where are the facts?

Select a race this season and use the race winner tyre strategy as the bench mark. Which drivers screwed up due to bad driver tyre management?

You can check the pit stop strategies at

Depends on what you mean by management bud.
If it's in relation to tyre wear through a drivers style then I'm with you that it's not been prevalent due to the nature of the characteristics Pirelli have incorporated this season.

If it's in relation to management from qualifying and saving fresh rubber and a spare set during qualifying through management of how you intend to approach the race weekend, then you only have to remember Lewis realizing that having that extra set of fresh tyres could win him the race and was realized after the preceding race saw Mark Webber's stunning progress from the rear of the grid earlier this year right up to I think it was 2nd/ 3rd. You'll know the one mate.

But like I said, tyre wear through a drivers style of driving or being more lenient went out the window at the start of the season due to the drop off characteristics of these new tyres from Pirelli.

In previous years it was glaringly obvious and was an advantage to the driver who was easiest on them.

But like I said I agree, this year it's made no difference, and that's all down to how these tyres perform, react and degrade....

I was with you from the beginning 
