I just found these at Discount Tire. They look great. 90,000 mile tread warranty, 3D siping, low rolling resistance. They have all the latest technology in one tires so no area of performance is compromised. The interlocking sipes still allow traction in wintery conditions, but they stay stiff and locked together during cornering to reduce squirminess and increase tread wear.
