what is the difference between the piolet's and the piolet PS?
Don't recognize either of those. Are you referring to the Pilots? They don't make the Pilots (MXX3) anymore; all Michelin currently makes are the Pilot Sport, Pilot Sport Cup, and Pilot Sport 2. As you have a '94 with stock wheels, that means you have 17" wheels (later Gen II's have 18" wheels), and I recall they do make a PS2 in the correct size for you (335/35ZR17 and 275/40ZR17). I have no experience with the PS2, but they are reportedly just an updated Pilot Sport and thus very similar. I do like the Pilot Sport's (been through four sets of them so far).
From what I understand, the Pilot Sport Cup's are a track tire, and thus their longevity is not suitable for the street unless you have a high tire budget and don't mind replacing tires twice to three times as often as the normal Pilot Sports.
