Feh, icy weather the last few days, so I bailed. I went to re-mount my Nokians, noticed that the studs on the back were getting pretty screwed up (turned sideways) and while straightening them with pliers I noticed that the tread blocks were separating from the plys underneath. I didn't fancy a blowout so I'm driving until Monday when it's supposed to be warm again.

New studs ordered, I'm going for W240s instead of W106s this time.
