I'd recommend finding your nearest Nokian dealer. I just bought a set of them for almost $20ea less than I paid for the exact same tires about a year and a half ago. WRG3s as well, but I bet there aren't too many people on here looking for those.
As far as I've seen, yes, just the R2s and WRG3s are being replaced (FYI, the WRGs are not a Hakka, they're an all-weather tire). They're in the process of rolling out the Hakka R3 and WRG4. There will still be a fantastic (better?) Hakka available in the future, but the R2s are on closeout from most suppliers. Sorry, should have mentioned that.
Thanks for the heads up on these! I picked up a set of the SUV variant for or Rav4 for $94/each shipped!
Custom Wheel Outlet - 320-839-8726 I saw them for sale on Newegg actually and these guys were the reseller and the price was amazing, I noticed they were local so called them and gave me the price direct and had them in two days, brand new of course.
