I ordered 2 sets of TSportline 20" TST wheels. One set of gloss black with the winter Pirelli tires and TPMS and I plan on getting some Nokian Hakka 8 studded tires to put on the stock 20" X wheels and swap the all-seasons from the stock wheels over to the metallic grey TST wheels. I rotate my own wheels/tires in my garage and it only takes 30 mins, so when it gets icy around here I will be prepared. I don't pick up my X till first week in March, but I couldn't pass up the holiday savings/discount from TSportline...plus I like different wheels for my vehicles.
On a side note, the Blizzak DM-V2 tires are great when new, but the compound is super soft and when you're down to 6/32" depth they lose most of the snow traction because the inner 1/2 layer is a different and harder compound.
