Dunflop Grandtek AT20's suck! I almost killed myself in the snow storm in Virginia. I hydroplaned across two lanes of interstate and ended up in the medium. Basically, I had NO steering control doing no more than 30 mph in a moderatively heavy snowstorm with little ice accumulation. It was 31* outside, so the ice was slushy.
The VSC and ABS worked flawlessly. Sounded like the cockpit of an airplane before a stall. After coming to a stop halfway down the medium, I was able to maneuver the vehicle back onto the roadway and continue without damage, but damn cheapo tires. The Suburban and Trooper following me kept on plowing. Another Cherokee in front of me completely lost control, at least we were only doing 25-30 and they were able to regain control after spinning 360* twice.
I have never had a vehicle(tire) do that before. Scared me straight, I got home and immediately ordered some Revo's, of course they are on national backorder.
I looked up the Dunlop AT20 on Tirerack. It scored a 2.8 for snow traction, which is borderline unacceptable. I can attest to that. This is an OEM tire? I rotated every 5K miles and checked the pressure religiously.
Mark86, you have about the same if not more miles on your stock Dunflops than I, I warn you to take it easy in the snow and ice, I almost experienced a bad situation on these very dangerous non-snow OE tires.
Now I am sounding like my father.
