Rear wheel drive BMW. Staggered Wheel set up. 1000mi. Chicago winter. At highway speeds in the dry (we’ll say over 80mph @ 40°f) it’s down right scary. I don’t feel like I get good traction and the car wanders a bit. At wide curves in the dry, the traction control light comes on and then when I straighten out the LSD kicks in and it has a lateral jolt. Oh, and when there’s strong winds… white knuckling it all the way to work. I took the car back to the shop because I thought it might be tire rub but they said everything was clean and then rebalanced. It’s been quite a winter this year-seemingly every winter scenario imaginable So that being said, in city driving with 4-5 in of snow @ -15° to 20°f under 45mph the tires are simply AMAZING! Remember, this is a rear wheel drive, very “torquey” car. Slush and cold rain it handled well. I might be so bold to say the tires handled better at 20° than at 40°f. The only winters I have to compare it with are Pirelli Sotozero 3, which handled great on the highway but not in the slush or snow. I truly wanted to love this tire particularly since they were really hard to come by in my area but on the highway it falls short.
