Kia Optima: Chassis / Tire (pressure & tread wear)

Check the tire pressure.

Tire Pressure

Rotate the front right and front left tires, and perform a road test in order to confirm vehicle stability.

If the steering pulls to the opposite side, rotate the front and rear tires, and perform a road test again.

If the steering continues to pull to one side, rotate the front right and left tires again, and perform a road test.

If the steering continues to pull to the opposite side, replace the front wheels with new ones.

Measure the tread depth of the tires.

If the remaining tread depth (A) is less than the limit, replace the tire.

When the tread depth of the tires is less than 1.6 mm(0.0630 in), the wear indicators (B) will appear.
