WS90 official update on longevity/durability for people that have had them a few years?

My previous set of WS-80 lasted 50,000 km before I retired them at 6/32" tread depth. I bought WS-90 to replace them and have 10,000 km on them so far. They had 10/32" when I installed them this year (down from 11/32" new), so they should make it to 50,000 km as well (10,000 km per 1/32" of tread wear). So I guess not any longer than WS-80, but we'll see.

I had WS80 for 3 1/2 - 4 years no problems. The WS90 was garbage right off the bat, I would never buy them again. I lost confidence driving with those tires, and I have driven in some pretty bad weather. They had 10/32 on them and I still went out and brought Nokian R3.

It's my second season with my WS90 ; driven about 20,000km first season ; I noticed that the tires are producing more noise. Otherwise traction in snow is fairly decent.
