When I went to my Toyota Dealership they didn't have 17" steelies. They only had 16"
Keep your all seasons tires/wheels. IF you decide to change to winter tires; go with 16' steelies or alloys and get 205/55R16 tires.
I been to many tire places and seems like they don't have 17" steelies. I really wanted 17" but had no choice. Maybe in 2015?
