These were my first choice too, but I went with what I guessed was a tougher rim for use with XL rated studded snow tires (and these rims just look good on a Black Kona). Also, they have an offset of 48, a bit closer to the 52 of the Ultima.
BTW, there has been no snow in BOISE this year - again! This is proving to be an expensive safety precaution which has made my drives less safe as I skitter around turns on studs and worry about lengthened stopping distances. It has been so warm here I have gotten little benefit of the cold optimized rubber compound other than early morning trips - mostly it has been 45-60 by early afternoon
did you buy these as a "winter" set to go w/ the studded tires?
If yes, then why don't you just take them off if it is warm and no snow in Idaho? How long does it take to do it, 10 MIN max (with wiping dirt and doing some greasing around) per wheel?
