jfoj - correct on the "DWS" markings. As the tire wears, the S goes first, then the W, followed by the D. As they disappear, you shouldn't drive in those conditions (snow, wet, dry). These tires look practically new.

I also agree on the health of the suspension components. I had freshened all the links in the rear end, so alignment to spec is doable. If you find you cannot align to within spec you know something is wrong in the bushings somewhere.

My front thrust bushings didn't last too long, but the key is to keep an eye on things and replace early. If not, you can shred some pretty expensive rubber very quick.
