Wow, it seems as though I started looking for Nokian Hakkapeliitta's this summer (highly recommended from posts on priuschat) - no one had them yet and now I'm looking and no one has them anymore! Anyways I had my heart set on getting them and I ended up finding an online place out of Michigan I think (Tires by Web 1-800-576-1009) that had both the R's and RSI's in stock and for a better price than any other place I had called before (even places that couldn't get them)...HIGHLY recommend these guys, plus they had free shipping and I had the tires in Connecticut 3 days after I ordered them. Someone mentioned them on the board and I give them another thumbs up. Anyways, I ended up getting the RSi's, does anyone know what the improvements are with the new Nokian Hakkapeliitta R's?
