I've been looking for wheels for our cars for winter tires and was able to pick up a set of wheels with mounted Blizzak WS70 on them for our Saturn SL2. A number of times I've seen that the multicell compound is only on the first 50% - 60% of the tire, which would be basically until 6/32nds and then they'd be less effective in snow (though I would think you'd want to change out snows around this level anyway). What I'm wondering is how these tires behave versus regular all seasons once the multicell compound is gone? Do they vitrually become an all season or is the rubber still softer than a typical all season? I'm wondering if I should have any major concern (performance wise) once at 6/32nds running them thru summer? 80 to 90 degrees Farheneit here in the summer, tires in question are 185/65/15 88T. Car could see up to 100 miles daily and could see a couple of 3+ hour trips each way during the summer.
