I've got Bridgestone RE-01R's on my ride that I had on year round in FL. We moved back to NC in Dec and surprisingly, they weren't all that bad. If the ground was cold, they would lock up easier in a panic stop, but otherwise drove normally.
Now the moment anything remotely white was on the ground, she was slippin' and slidin'.
The 01R's are getting worn though. Bridgestone has up to $100 mail-in rebates on their tires this month, with the RE-11's getting $100 and the RE-760's getting $75. I can get a set of RE-11's for $696 or the RE-760's for $453 (plus shipping and mount/balance of course, after the mail-in rebate).
Decisions, decisions...
