That's pretty good. On our Montana van, we got 3 seasons on each of 2 sets of WS-50s, about 14,000 miles / 22,500 km. With one season of 4,000 miles / 6,400 km on the WS-60s, it looks like they will have the same lifespan.
The Blizzaks end up being used more than I would like in warm, dry weather - North New Jersey winters normally don't stay very cold for long periods, and the roads are cleared of ice and snow quickly. My wife demands excellent ice and snow performance over tread life, so she gets Blizzaks on her van. Tires cost less than body work and hospital bills. And happy wives are priceless.
The Montana van is very heavy in front, so the WS-60s that were on the front last year are significantly more worn than those on the rears. The ones that were on the rear look almost new.
As someone else mentioned, the WS-60s have more wear in the center than on the edges. That is very strange, the edges of the front tires have always worn most on all of the other tires I've had on the Montana.
