While I can't comment if these are the BEST tires, I can tell you for certain before winter in New Hampshire, I ditched my "Persuit" tires that came on my PIU for:
245/55ZR-18 CONTINENTAL EXTREMECONTACT DWS 06
Suggested by the very nice people at Tire Rack. I had no preference going into it since I have been a Marauder and Suburban guy. This is my first mid-size SUV.
My impressions thus far. Maybe 5k on them:
Darn good
Solid wet and dry performance. Nice cornering. Low highway noise and pretty smooth ride. It's an SUV not a Town Car so I'm not expecting land yacht comfort.
Had some sporadic snow in NH last month or so. Absolutely no issues humping over 12" up hill out of my driveway and then 100 miles (mix of highway and back roads) to work and back on what the state and towns call "plowed" roads...aka pretty fk'n messy.
I tried to have some fun, and you know what I mean if you live in snow land, but was having some issues. Maybe it was the AWD, maybe the tires, probably both, but I was left day dreaming of epic donuts in my Marauder in open church parking lots. Oh well. I did manage to break free and do some ass sliding, but it took some work. If I didn't know I was in a blizzard and driving normally, I would have said it was dry pavement.
Even my mechanic who mounted them said while he vowed to never mount a Continental tire out of principle (maybe he's a Michelin man?) , he was pleasantly surprised when he test drove it.
All in all, I'd give them 2 thumbs up thus far. But that's me. As always, your mileage may vary.
