A tire survey thread here in 2009 for MY2010 found three different brands/models of 15" tires, and three more of 17" tires. I don't recall any similar survey for the 2012.
Mine came with Goodyear Assurance Fuel Max and as OEM tires they haven't been too bad. Even though I'm rapidly closing in on needing to replace. Human nature to try out change? I think I'll try upgrading when I switch.
