All well, 40 is of course correct - apparently my memory failed here.
Now, as an explanation, for one, my importer recommended the tire specifically for the car, the load index is different, yes, but regardless of how you calculate weight distribution, there will never be over 1230kg on the front axle of the 159.
And by the way - my papers allow load indexes down to 88 actually (although 17 inches)
And the 'why would they do it if..' is not nevessarily a good enough reason, Alfa tested the size and found them best fitted, however, funnily enough, coming from an Italian manufacturer.
I have been at speeds well above 230km/h and have them both in winter and summer edition, for the second generation 159 in my lot. And - no problem whatsoever - depends what you like in driving style.
