I think it was a problem like Brawn in 2009 more than anything. The car generates most of its tyre temperature through traction/braking events. Look at all the races where the traction and braking demands were high – the Ferrari had no temperature trouble. Monza says otherwise; but the traction events are too few and far between to be counted as a traction heavy circuit.
So unless the cornering events other than traction/braking is putting immense loadings on the tyres; such as a place like Suzuka; they struggled.
