I have only had these tires a short time, but we got hit with about 8 inches of snow so far this storm. With OEM Continental All Season tires I was skating around in my Jetta Sportwagen in any amount of snow. After the first storm this season I ordered a set of the Altimax Arctic snow tires mounted on new rims. Boy am I glad I did, today's storm was a few inches of fresh powder that turned into hard pack during the morning rush hour. I was able to maintain grip on everything from the hard pack through the six inches of untouched snow in my driveway when I got home. I tested them out on the hill up my street and I was able to make it up without any trouble. I saw the video test for these tires here on tire rack where they put them up against 2 other brands and I am not disappointed in my choice.
I have run them for 2 weeks on cold but clear pavement and was pleased with the tire noise and feel. The road noise from the tires is no more than the OEM tires, likewise I have not had any reason to not be confident in the Altimax Arctic grip on dry surfaces. I no longer drive my cars like I stole them so I haven't come near finding the limits on these tires and I don't plan to. Really the only difference I feel with them is on a higher speed tighter curve, like a highway entrance/exit ramp. In that situation I can feel a slight rumble when the deep tread is under lateral stress.
If it wasn't for the holiday shipping crush, I would have had these mounted and balanced and on my doorstep the next day after ordering. The UPS driver was nice enough to disguise the stack of tires with my garbage can.
I am very happy with Tire Rack, their customer service and my new snow tires.
