The 2015 Kia Optima does not come with a spare tire. Try not to worry, though! If you do run into tire troubles, you can use the Tire Mobility Kit that’s included with your car instead.
This kit includes things you can use to patch or repair your tire’s damage, then re-inflate it so you can make it to the shop. While it’s not quite the same as having a spare tire on hand, it can definitely come in handy if you have problems while you’re out on the go.
