Seems like both of you guys are hinting I should replace my tires at the end of this season. Maybe there will be some good off season deals on Hakkapeliitta R3s. When I pulled the tires out of storage they seemed a little bit more worn than I remembered.
- the original rubber on the tires switches closer to an all-season as it wears beyond a certain point - it's a dual-layer implementation if I remember correctly. So, depending on the tread depth left, it may not still be a winter tire rubber you're riding on. Mine are older, but have probably fewer overall miles on them. I'll swap on new ones maybe after this season.
One of the tires in my set was worn down to the point of almost exposing the treadwear markers. I decided to put that one on the front axle because I was worried that it might cause more slippage with RWD. That's good information though, I assumed the compound was the same the whole way through. Since you said "OEM winter tires", do you know if the Nokian tires use an identical compound the whole way through?
