I've done my research but I'm having a hard time finding advice on my specific situation. My tire purchase is decided: Nokian Hakkapeliitas. I've been using them for 20+ years and they are amazing. When I lived in Vermont I used studded but now in Eastern Washington I use the R2. So to save $$ I'd like to go with 15" wheels. I'm undecided about steel or alloy but my bigger concern is tire size. Eastern Washington definitely gets some snow but not frequently and usually just 3-4 inches at a time. Roads are often dry or damp. 20 mile commute on highway to work. We also have a 2013 Subaru Outback in the garage that I can drive on slippery days but I also want to be prepared for any weather that develops during the day while I am at work. Currently considering Tire Rack or Discount Tire's 15" steel wheel with 185/60/R15 Hakka R2s. Does anybody have this set up? I may decide to spring for alloy because I fear I won't like the look of the steel wheels. Thoughts? Any warranty issues with using 15" wheels? Yesterday the local Ford dealer said the Ford does not sanction any wheel size but the 17" oem. As a daily driver does 16" make more sense in my situation? I already curbed a wheel so the larger sidewall of the 15" is appealing. Can you tell a difference in ride quality between 15" and 16"? Thanks for any advice you can offer...
