I have had my Dunlop SJ5 true winter tires installed on monday morning and we have had our first snow in Quebec city last night. Those in the snow belt know how slippery the first snow is, lots of car crash etc. I could not even move my C2500 Silverado as this 5500 lbs rock, equipped with new all season Michelins kept gettting stuck in 3 inches of snow. My son complained also on poor traction with his Mitsubishi Lancer with winter tires. Well I thought it was a good opportunity to test the Murano and the Dunlop tires ability under adverse traction conditions. What a joy! The Murano is amazing, it was so slippery it was possible to spin the 4 wheels yet directionnal stability and accelaration were impressive. I tested the time of reaction of the power transfer to the rear wheels and it is almost instantaneous although there is a slight advantage in using the AWD lock. I did not feel any perceptible change in the lock position when the system engaged or disengaged at 19 mph. I could perform some tests on the road (streets) as there was nobody out last night. The MO has the directionnal stability of FWD and the ease of control of a RWD when it starts to skid outward. I could engage the ABS system going fast and downhill hitting firmly on the brake, but the car stopped quickly without activating the ABS when braking to stop normally. This car is the most performing and stable vehicle I have ever driven in the snow. In this respect, I believe that the Dunlop Grandtrek SJ5 are very decent winter tires, in fact the best I ever had. I do not doubt that Nokians, Toyos or Blizzaks may be better, but the closest match to the Dunlop, when and if available were twice the price.The braking and cornering abilities under very slippery conditions where other vehicles experienced severe traction problems speaks for itself. The Dunlop SJ5s are DOT approved, rated Q and run fine on dry road at speeds up to 90 mph. For once, I feel the winter will be too short.
