CalgaryG,
Try the Eagle F1 All Seasons... they are new from Goodyear, and I've got the 18's on my G and they work very well in the dry, rain / cold rain, and even in light snow -light snow. +very good for the price - not too overpriced like some of the michelin tires. Handling is excellent overall.
The Eagles can be a little loud, and harsh because of the treadpatter and rigid carbon fibre sidewalls... but then again, with 19's... it doesn't matter what tires you have, it will ride harsh.
I use to have the Oem summer only Bridgestone re050a's and although they are very good in summer, rain... when it gets just a little colder, it starts to spinout and slide easily.

Looking for a less expensive option? ---also look at the continental extreme contacts ... or better yet, the Kumho ASX ---but in the ultra high performance all season category. I had the Kumho ASXs on my friend's car and it also is a very good tire - quiet too! Good Luck with the Chinooks!
