Tires: sidewall size for a 2004 Kia Optima, kia optima, 2004 kia optima

Question
Could you please tell me what sidewall sizes fit a 2004 Kia Optima.  We currently have 205/55-16

Answer
Susan,

Stick with the current size.  Not only is this an incredibly popular size, there will be plenty of options in the tires available.

Besides, this size has the advantage that the car was designed so that it will fit and not rub on anything.
