Standard fitment was a 590-14 crossply tyre, for which a 165R14 radial tyre is a suitable replacement size. Estate models had a 640-14 crossply, which can be replaced with a 185R14 radial tyre.
Fiat's version of Pininfarina's European saloon style (Austin Cambridge, Peugeot 404 etc) had smooth 6-cylinder engines and gently modernised running gear over its lifetime. A nice large family saloon.
