I have been a fan of Hakkapeliitta winter tires since I put them on my 2012 Volt. Ran them for 5 winters without a problem and loved them. Started looking for them in Toronto and found out that Kal Tire has a strangle hold on them. They want $290 per. When I lived in Guelph, I dealt with Dettmer tires quite a bit. Very knowledgeable (especially Mike at the Eramosa/Stevenson location). So I called them up and they ordered mine in (they will apparently be arriving tomorrow) and they will store them for me until I get them installed in November. $258 each for the R3's @ 235/45/18. Mike said there might be a rebate by then as well, but he currently only shows availability of 100 tires in this size. It is worth the drive to Guelph for me from Toronto (I can see old friends while I am there), but if you are near Guelph give them a call. I verified that they know how to jack a Tesla and they are sourcing TPMS for me. Now to find a nice set of winter rims!
