Question
What sizes of tires&rims can I put onto,my 2003 Kia  rio ? It has 14in rims on it now,can I use 13in ?

Answer
Richard,

On every vehicle sold in the US - and I understand this is a worldwide practice as well - there is a sticker commonly called the vehicle tire placard - that lists the original tire size and the proper pressure for that size.  The placard is usually located on a doorpost or in the glove box but sometimes it is located in the trunk or on the fuel filler door.

BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.

That is the tire size you should use as it is guaranteed to fit.

According to Tire Guides, the vehicle tire placard on a 2003 Kia Rio ought to say the original tire size was 175/65R14.  This tire size is fairly popular, and you should have no problems finding suitable replacement.

But to answer your question, Discount Tire lists other sizes to fit you vehicle:
