What does checking for tire bulges indicate?

Checking for tire bulges is an important inspection step because bulges often indicate possible structural damage to the tire. When a tire has a bulge, it suggests that the internal structure of the tire may have been compromised, which can occur due to various factors such as impact damage, manufacturing defects, or excessive wear. This damage can weaken the tire and increase the risk of a blowout while driving.

In contrast, bulges are not typically associated with normal wear and tear, a loss of pressure, or improper alignment. Normal wear would show signs such as tread wear patterns rather than protrusions. While low pressure might sometimes cause the tire to be misshapen, bulges specifically point to more serious damage within the tire itself. Therefore, identifying a bulge is a critical step in assessing tire safety and determining if a tire needs to be repaired or replaced.
