What should you check for when visually inspecting tires?

When visually inspecting tires, it is essential to check for cracks, bulges, and foreign objects embedded in the tread because these factors can significantly affect the tire's performance and safety. Cracks may indicate aging or degradation of the rubber, which can lead to tire failure. Bulges often signal internal damage or weak spots that could result in a blowout while driving. Additionally, embedded foreign objects, like nails or other debris, can compromise the tire’s integrity and lead to slow leaks or sudden air loss.

Checking for these issues during an inspection allows for timely repairs or replacements, enhancing overall vehicle safety and performance. Other options, while potentially relevant in certain contexts, do not specifically address the critical aspects of tire safety as directly as the presence of physical damage or obstructions.
