I have had the Continental cross contact LXs(265/65/17s) (30.6") on my 04 since last November. They have been great in the rain and the little bit of snow we had here in Raleigh, 1 day this past winter, (Grew up in MI, so I do know what real snow is, This was not real snow) But I will not buy them again, I have had balance issues (steering wheel vibration 55-65MPH),Had them road force balanced but the vibration came back in a month, and they seem to flat spot over a weekend if not driven. I had high hopes for these tires since they were ranked fairly well on tirerack.com but I have been disappointed overall. I paid about $730 OTD for them from discount tire.
I ordered 265/70/17(31.7") Bridgestone Dueler A/T Revo 2s for my 08. Also put on a Daystar 2.5/1.5 lift this past weekend and have Spidertrax Wheel spacers on the way. They are about $830 OTD from Discount, but there is a $100 visa rebate card right now. So just about the same price as the Continentals for a hopefully better overall tire. Almost anything is better than the stock Dunflops.
If you see Canada Snow even for a week a year I would go with a A/T type tire. I would not buy the Continentals if I still lived in MI.
