I remember the Original XVS's, [185/70HRI4 ] still have the spare in the trunk, orig. campy Daytona, never mounted.
But the other 4 were deleted toute de suite, as they were death traps in the rain. Factory on my '82.
After that mostly Goodyear 205 gatorbacks ( autocross daze ), and Fulda 205/60R14 all seasons.
Currently Falken Azinis, 195/60R14 86H RT615K - good tires, just a bit too loud, but boy, do they stick.
Prolly take a good look at the Pirelli's CN36 at next change...
