Rampage108--- Since you're like me from mountainous & snowy WA State; I highly recommend to only consider those A/T type tires that have the coveted "Snowflake/Mountain" rating stamped on the side of the tire sidewall, and disregard those models that don't have the special rating. These are tires that have successfully passed stringent testing in severe snowy conditions, and most everyday A/T's fail the test except a valiant few. Here is a sampling of those that are considered all-year everyday type A/T's (non-Winter specific) and that have the Snowflake/Mountain rating:
A. General - Grabber AT2
B. PRO-COMP - All Terrain
C. Good/Year - Wrangler DuraTrac
D. Good/Year - Silent Armor
E. Dunlop - RVXT (although not available in 18")
Here is a TireRack article explaining the Snowflake/Mountain rating:

In addition; be weary of individual tire weight and try to focus your maximum tire target weight to no greater than 45 lbs max individual tire weight. Our OEM factory tires only weigh 34 lbs each, so try not to exceed 10 lbs over OEM weight to maintain safe braking with OEM brakes and good overall MPG.
www.TireRack.com is a great website to verify individual tire weight.
www.1010Tires.com is a great website to confirm "Snowflake/Mountain" rating, as it is indicated in a bright blue symbol next to the tire model.
