The wheel sets are backordered by four weeks.
They use Pirellis which do not have a tire to handle my level of snow. Besides, I have had very bad experience with Pirelli in the past.
By assembling, I get the wheels earlier and the ones I want, Blizzak LM60. Arguably, they do not have the performance level of the Pirellis but I cannot remember when I have ever gone over 130mph in the winter. I need snow performance over road performance in my area. In the end, a set of 4/ 408s, 2 front, 2 rear with offsets, 4 LM60, monitors, mount, wheel balance, pickup and delivery over one hour away to/from my office with loaner. Separate delivery of tires directly to my home-$3600 or priceless!
Sometimes, customer service counts too. I am pleased.
