Why do wheel studs break?

Wheel studs can break due to several factors, including over-tightening during installation, which can create excessive stress on the metal. They may also fail due to fatigue from repeated stress cycles, particularly in vehicles that experience heavy loads or harsh driving conditions. Corrosion from exposure to moisture and road salt can weaken the studs over time. Additionally, improper alignment or damaged components can lead to uneven forces, further contributing to breakage.
