Every time the air pressure in the tires is checked, carefully inspect them for mechanical damage to the tread and sidewalls, small stones, nails and similar objects stuck in the tread, as well as signs of severe tread wear.
Pay special attention to the following tire defects:
- local swelling or bulging of the carcass in the tread area or on the sidewalls. A tire with a similar defect must be replaced;
- cuts, cracks or delamination of the sidewall frame. Replace the tire if the carcass cord is exposed;
- tire tread wear limit.
The tires that the vehicle is equipped with have wear limit indicators molded into the tread. With a decrease in the depth of the tread pattern to 1.6 mm, smooth transverse strips 12.7 mm wide appear on its surface, located with a certain step around the circumference of the tire.
Worn tires do not provide sufficient traction when driving on wet road surfaces. Therefore, the tire must be replaced if three wear indicators are visible on the tread (or more than three).
