Macca have traditionally had great mechanical grip. I think there are a couple of reasons; The biggest factor IMO is the engine. They clearly ahve the most powerful and driveable engine out there. The brawn shared the same slow speed brilliance that the Macca did this year.
Also Macca have, over the last few seasons, lent towards a short wheel base, from my understanding this also aids in mechanical grip/low speed stability.
WHen it comes to next years front tyres i have an interesting theory. We all know a fewe things, they will be smaller, ie they will yield less grip and require the car to be set up differently so not to over stress them. We also know Hami asks a lot of his front tyres, where as Jens is pretty forgiving on his.
I think Lewis' style will also need to be tempered as they will be carrying a lot of fuel and this will make it even more important not to 'lean' on your tires too much.
Lets face it if you are easy on your tires it will be a huge advantage as it will free up your strategy a bit.
And i actually think that next season we will see a short first stint being the prefered option...
If your tires are used up and you pit before the guy in front of you, you will leave the pits wiht the same fuel as him but newer tires, its possibly you will rejoin in clean air and run your fastest lap times to date. Your opponent will still be on old tires and likley lapping slower than you are on your new rubber. He pits and you jump him. Its just the reverse to this season.
