Don't know about the price of the P Zero's normally, suffice to say that virtually everyone I have spoken to has told me to jump on this set claiming that I have a bargain.
I am guessing that average price of P Zero's would have been A$500, but that maybe for the Assimetrico or Rosso types.
Haven't tried Toyo's, although they did well in a Giant Tyre test in CAR Magazine recently. They have a "El Cheapo" or "K-mart Red Light Special" type of reputation...although I must say that may well be unfounded.
Latino, the quietest tyres I have found are Yokohama AVS Sports on a friend's Peugeot 307 2.0 . They seemed to be super quiet and very grippy...must be the soft compound rubber
Apachet, we certainly do have Falken, and I am a big fan of them. They are extremely good value for money. Considering Falken is owned by Bridgestone and "copy" a lot of the Bridgestone designs for a fraction of the cost. I just didn't consider any Japanese tyres purely on the fact that I wanted to stick with a European tyre.
I have been extremely impressed with the P7000's, and have been advised by many people that the P zero's are an improvement on the P7000's.
Paulo, my wife's 147 Sele came with the Goodyear F1's, and they seem to be OK. And your suggestion of the new F1 GS-D3's is a great one too. They are made in Germany and came 1st or 2nd in the tyre test I was mentioning before.
