    what have you 328 owners (or 308s with 16" wheels) found to be the best cold tyre pressure for road use?

    What is recommended in the handbook?

    I run 34 front 38 rear but Horsey tells me he runs the opposite, Giovanni gave me those pressures, reckons you need 4 psi difference front/rear, which makes sense

    I think Horsey runs 30 all round and he's the gun

    You say it makes sense, but it's a Ferrari, so nothing makes bloody sense. By the book tyre pressures for the 355 are 34f 32r fwiw...so where's the sense in that?

    my manual says 33psi <200kph and 36psi >200kph

    nothing about differences between f/r but Giovanni has done a lot of trackwork with a pyrometer

    It depends on which tyre - different pressures and F/R balance for each tyre

    I have no experience with road tyre 16's on a 308, but Modelers settings would be a good starting point.

    Not that it matters, but I run cold 32 psi on the front and 36 psi on the rear of my 348. :):)

    I have NEVER played around with pressures on it though. No track to even bother wasting my time doing it. :(:(
