Tire Wear

WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Using tires and wheel other than the recommended sizes could cause unusual handling characteristics and poor vehicle control, resulting in a serious accident.

Measure the tread depth of the tires.
Tread depth [limit]: 1.6 mm (0.0630 in.)
If the remaining tread depth (A) is less than the limit, replace the tire.
NOTE: When the tread depth of the tires is less than 1.6 mm(0.0630 in), the wear indicators (B) will appear.
