I live near you in Hunt Valley, MD and I use Michelin Pilot Sport A/S on some aftermarket G-Games wheels:

19x9.5 - 245-35
19x10.5 - 275-35

these work great in the small snow storms we get around here. I have them just in case it starts to snow when I am at work. you know how unpredicatable weather is around here. anything more than four inches and my G is not going anywhere.
