thinking to buy a new set of P Zero's to my ST. What do you think about their performance? i know they are rock hard but here in Turkey they're a lot cheaper then Michelin and Continental.
and we don't have Eagle F1's for the size of ST.

Can you get toyos in Turkey. They are very good tyres if a little soft. Another brand that i hadn't herd of until i got my focus was hankook. Have got the ventus v12 evo and they are amazing. Full boost in 2nd gear and no wheel spin

try and avoid PZero if you can, they are only good in dry, generally though they are a bit better if you drop them a couple PSI, mine better in the winter when I do this epsecially on damp/wet/greasy roads, just don't put the recommended 32 in fronts.

I guess weather in Turkey is generally better than over here.

If you will only be using them on dry and in heat they may not be too bad. To be sure though, I'd rather Avon ZZ3, Toyo T1R, Parada's also get good reviews.
