I got my "winter" (really fall/winter/spring) wheels from Discount today.
Wheels: 18x8 OZ Hyper GT HLT
Tires: Continental ExtremeContact DWS 06 all-seasons in 225/40-18.
That was the TR size recommendation. For my purposes (basically winter street rubber), I like the smaller size. If needed, I can fit chains under there to get out of an icy/snowy ditch. Then: OFF!
It took me a little getting used to the difference from stock (visually). I think that if I were looking for these to be track wheels, I'd opt for 235/40-18 size tires.
Ride is very smooth on this setup. Seems less jarring in general.
