I am a fellow Parker resident. I have a 2000 OBW. I have tried the Blizzack, and Nokian wr. Both had VERY poor tread life! I then went to WALMART of all places and bought a set of Goodyear American Eagles. 70K warranty and great in the snow and rain. I too average 5-600 miles per week and these skins have been execelent! The tires were about $70.00 ea with warranty package.
