Technician a says the appearance of tire wear indicator bars indicate that tire pressure is low and therefore pressure should be increased. technician b says tire indicator bars are a quick visual warning that tire tread is worn down to the unserviceable level and the tires should be replaced. who is correct? tech a tech b both tech a and b neither tech a or b

The answer is Technician B

Explanation:

How you drive your car to how you maintain your tires will always tell a lot about your car’s tires. In the long run, bad tire maintenance habits and reckless driving style will cause tire wear. As a result, a tread wear indicator will appear. Most quality tires come with tread wear indicator bars that are molded evenly and look like small, thin strips of rubber placed between the grooves of the tire tread. These bars will gradually become visibly flushed when the tire is worn out beyond its required limit. This will, therefore, mean one thing; replace your tires before they wear out completely.
