What type of wheel damage is considered non-repairable?

Cracks in the wheel structure are generally considered non-repairable damage. Wheels are designed to withstand significant stress and impact, and cracks compromise their structural integrity. Welding a cracked wheel is often discouraged because the heat from welding can weaken the metal and create new stress points, potentially leading to catastrophic failure. Even seemingly minor cracks can propagate over time, especially under heavy loads or during impacts. Additionally, cracks can be difficult to detect and repair reliably. Other types of wheel damage, such as minor bends or dents in the rim, may be repairable by specialized wheel repair shops, but cracks in the wheel's spokes, hub, or mounting surface are typically deemed unsafe and require wheel replacement. The risk of wheel failure due to a crack outweighs any potential cost savings from attempting a repair.
