Kia Optima: Tires and wheels / Tire replacement

Kia Optima DL3 2019-2025 Owner's Manual / Maintenance / Tires and wheels / Tire replacement

If the tire is worn evenly, a tread wear Indicator (A) will appear as a solid band across the tread. This shows there is less than 1.6 mm (1/16 inch) of tread left on the tire. Replace the tire when this happens.

Do not wait for the band to appear across the entire tread before replacing the tire.

The ABS works by comparing the speed of the wheels. The tire size affects wheel speed. When replacing tires, all 4 tires must use the same size originally supplied with the vehicle. Using tires of a different size can cause the ABS (Anti-lock Brake System) and ESC (Electronic Stability Control) to work irregularly.

✽ NOTICE

In order to maintain optimal driving performance, we recommend replacing tires with the same specification and type as originally installed in your vehicle. If not, driving performance could be altered.
When replacing tires (or wheels), it is recommended to replace the two front or two rear tires (or wheels) as a pair. Replacing just one tire can seriously affect your vehicle's handling.
