Just looking into this a bit more!
Basically the 96 load rating is a trade off....
Note that the standard 17" wheels for the 2.4 and 3.2 is actually a 98 load rating, and the 1.9 is 93 load rating. When you go to Ti, it all goes to 96 load rating ( presumably as no one makes a 98 tyre in this size).
For info: a 92 load rating is 630kg, 93 is 650kg, 96 is 710kg, and 98 is 750kg
The 19" Ti wheels are on several models: (remember these are all at max weight (+550kg)
The 'heavy' 2.4, which is 'up to' 1220kg on the front axle (610kg per wheel, 'just' under the 92 weight limit (of 630kg), you can see why they are not recommended, and why 96 is the minimum load rating for any 2.4).
The 1.9 front axle max is 1150kg (575kg per wheel).
The rear max for either is 1050kg (525kg per wheel).
Max payload (inc driver) is 550kg, which which will be severely biased to the rear (the driver is approx over the centre point of the vehicle), and rear passengers are almost directly over the rear axle (average person is 75kg for comparison).
So for the rear you have slightly more safety margin than Alfa recomend for their fronts on the 2.4 when fully loaded.
