As the saying goes, "The jury is still out on this one." I think that I am going to end up a one-tire-set guy. I'm trying to. But by this summer, I might be pushing my car hard enough to want the summer tires back on: in which case I will not avoid the off again and on again routine. But will I go winter tires? Not until the Nitto Motivos are used up: unless I manage to scare myself badly enough to ditch them for the best winter tires I can find. I tend to wait once I've made up my mind. So having already made my decision last fall, and not regretting it in the least thus far, Motivos it is. Come summer, we'll see if I leave them on.
Right now I am at my dealer getting my Eibach rear sway bar on (soft). I drove through typical Utah, lowland winter conditions: lots of slush between lanes, people driving carefully (except for the inevitable handful who don't: have seen three off the road so far, one on the freeway backwards against the median wall, front bumper ripped clean off). The acceleration of this car is amazing with AWD and A/S Motivos.
