Michelin Premier LTX and Pirelli Scorpion Verde All-Season Plus. The OEM tire you probably have is the Michelin Latitude Tour HP, and the reviews for that one are not nearly as good. Tire brands don't just sell one tire; they have many different ones. Michelin makes some of the best tires. Pirelli is also good, but not as good.
ThePirelli Scorpion Verde All-Season Plus is $50 less than theMichelin Premier LTX per tire on TireRack, but the Michelins are a little better. If you have something against Michelin, get the Pirellis as the performance difference is probably worth losing to save $200.
