I've been reading on this site, as well as a few others (including tirerack) about winter/snow tires. It was recommended to go with "minus one" for winter tires. So after a few days of research, I ordered Blizzak DM-V2 at a size of 225/65R17. OEM is 225/60R18. When getting the tires/wheels (I ordered steel rims for a dedicated winter/snow tires) installed, one of the guys working the front desk started talking to me about how that could void the warranty on the Outback, destroy the transmission, and kept saying "good luck with those wrong sized tires". I'm pretty much a newb, so it naturally has shaken my confidence in minus one sizing and whether or not this is going to mess up my Outback. I have a 2016 Outback 2.5 Limited. Does anybody have any thoughts on this issue?
