For what it's worth, I'm going to the same size tire all around, in the 18" size the next time around. Going with all season speed rated, and we'll see how that turns out. The Conti M+S I have now, 18 and 19's have been fine so far with 12K on the clock so I can't complain, but still, I think I'll be happier in the long run for how I drive with a set of the same all seasons. BTW, I talked to a tire dealer and he said the NA Cross should be good for caliper clearance down to 17's. Mark
