Well, I took a leap and bought these 235/45ZR17 Falken Ziex 512's. Everything...price,warranty," Consumer Reports " #1 rating, price... seemed right. They are however, the first all-seasons I've put on this car. After the original G-Force's and my Yokohama A520's, I consider these a bit of a compromise. So far though, I'm pretty pleased with them. They don't seem to be as razor sharp as my previous tires but they,ve held every piece of road I've thrown at them so far. They're also much quieter and more comfy riding.
