F12 Winter Tyres

Hi,

My original set of Sottozeros are about 6 years old now, and was looking to replace them.

Its getting harder to find the OE sets for this car, it took me a couple months to source the original K2 Michelin PSS in the UK.

I was checking out Pirellis website, and shows there is a new PZero Winter Tyre in Ferrari Spec in the 305/35r20 rear size, as well as the 255/35R20 fronts.

Has anyone heard of the new PZero winters, and how they are different to the Sottozeros?

Lastly, does anyone here know if the Sottozeros that Ferrari supplied were a "F" spec tyre, or just the generic Sottozero?

Thank you!
