What action is recommended if a tire shows signs of wear?

When a tire shows signs of wear, it is essential to prioritize safety and performance above all else. Replacing the tire is recommended because worn tires can significantly affect traction, handling, and braking ability, which are crucial for safe riding. Tread depth plays a vital role in water dispersion and grip on various surfaces, and could compromise the motorcycle's stability and rider safety if the tire is not replaced promptly.

Although checking air pressure and continuing to ride can be actions that may apply in different contexts, they do not adequately address the immediate concern when a tire indicates wear. Continuing to ride on a worn tire increases the risk of a blowout or loss of control. Checking air pressure is a good practice for tire maintenance, but it does not rectify the issue of wear and would not eliminate the dangers associated with riding on a compromised tire.

Thus, the recommended action when noticing wear is clear: timely replacement ensures that the motorcycle operates safely and effectively.
