No luck with wear ratings. I've read some reviews from tirerack users on similar winter tires from Dunlop and not any mention of fast wear. Some dude said he kept them on for 80k, which I dont believe.... I'd say they're good for atleast 15k-20k.
Well drove on them for ~800 miles. The ride is definitely softer due to deeper, softer treads. Handling suffers just a tad as it loses some responsiveness. Still very capable.
In the snow, handling and accelerations during turns are excellent. The cabin I rented in VT was up a very steep hill and was unplowed with about 4-5" of fresh snow over a hard packed snow base. No drama, just digged in and went up without a slip. My friend's WRX was all over the place and another friend's TL was stuck at the bottom of the hill. I would definitely recommend these tires to anyone living in the snow belt. A completely different beast on snow with these shoes.
I got them off Tireworks out in Canada (Ontario) back in December. They were having a sale on them for $185 Ca each + shipping. Not sure if they have them still but I'd try giving them a call. http://www.tireworks.ca 1 888 536 6176.
