The new ones at our dealer were also 13's, standard steel wheels. Most of them are, but for some weird reason a lot of the 2011's had 14's. Maybe they ran out of 13's that week and put 14's on
I honestly don't see anything different about our X17Z suspension wise, their really is no reason you could not go with 14's.
Just curious, what is the actual size?
