S standard tyres were Pirelli PZero Nero.
The only other premium tyre with the correct load rating is the Continental Sport Contact 3 (but check as they also do a 94Y...)
I have used Pirelli's since new on the 159 Ti (same size) and when I was offered Accelera's for £68.00 each, I thought they were worth a punt, and now they are on, I have had them in all sorts of conditions in the last month ....and they are fine, notghing to worry about, they are on the front and break away slightly earlier and differently from the Pirelli's but more progressively in push on understeer situations.
Damp/wet traction and braking seem much the same, though havent tried a full 'achors away' stop.
As the P Zero is useless in winter, this is when I tried them.
Theyre worth a pop, though was warned by the tyre fitter to keep an eye on them for splits and bulges as they can be indifferent in quality, though the PHI ones in this size seem better than the even cheaper range.
