TireRack just delivered my set of winter tires and new wheels for the Crossfire:

I ended up getting four ASA ST3 18 x 8 wheels in a bright silver paint
along with two 225/40VR-18 Bridgestone Blizzak LM-25 XL for the front and
two 225/45VR-18 Bridgestone Blizzak LM-25 XL for the rear.
These taller rears will maintain the front to rear stagger.

According to TireRack the 225 size will reduce the rear contact patch size
and provide better snow and ice traction.

I originally ordered the Dunlop Winter Sport M3 in the same size however, after
waiting one month the 225/40 was still backordered and had no expected arrival date
so I switched to the LM-25's from Bridgestone.

I have used Bridgestone's in the past on my SC400 with great success.

I do plan on adding some weight to the rear in order to put a tad more downforce on the
rear wheels.

I will let you all know what shakes when the flakes fly. I will be putting these wheels and tires on the car around the Thanksgiving time frame and probably pulling them off in Mid April.
