Most any tire store will look it up on the computer. If you want a size other than what the computer geek will sell you, sometimes you have to sign a wavier.

If your car is stock, it will also show in your owners manual in your glove box. It may have a maintenance section and it will be under Tires/wheels. The book is also required to publish air pressure recommendations.

l hope this helps!

there should be a decal either in the door jamb or glovebox that shows correct tire size

The standard Sonata came with a P195/70R14 and the GLS came with a P205/60R15 90H tire.
