Alloy wheels, while stylish and performance-oriented, can be vulnerable to damage in everyday driving. From curb impacts to deep potholes, wheels face risks that can compromise both appearance and safety. Wheel Daddy partners share the most common causes of damage and how to avoid them.
1. Curb and stone edge damage
One of the most frequent causes of wheel damage is contact with curbs or stone edges. This often happens during parking or when maneuvering in tight spaces.
How it happens
When a wheel scrapes or hits a raised curb or barrier, the impact can leave scratches, dents, or even cracks on the wheel surface. Even a small dent can disrupt wheel balance, leading to vibrations at speed. If left unrepaired, such damage may develop into deeper structural problems.
2. Driving straight over raised edges
Hitting a raised edge or obstacle head-on is particularly dangerous for low-profile tires paired with larger wheels (18–20 inches).
Why this occurs
With little sidewall cushioning, the impact force transfers directly to the wheel. This can result in bending or even cracking. It’s similar to driving a wedge against the rim—when the tire can’t absorb the energy, the wheel takes the full shock.
3. Speed bumps – hidden risks
Speed bumps are designed for safety, but hitting them incorrectly can be destructive for wheels, especially when running large wheels with thin tires.
What happens on impact
Approaching too fast shifts the car’s weight sharply downward at the contact point. If the tire doesn’t provide enough cushioning, the wheel absorbs the blow, which may cause cracks, dents, or distortion. Repeated hard impacts can also unbalance wheels, creating vibration and handling issues.
4. Deep and sharp potholes
Potholes remain one of the biggest threats to alloy wheels.
Impact mechanics
When a wheel drops suddenly into a pothole, the entire weight of the car is concentrated at one point. Low-profile tires provide little shock absorption, so the rim bears the full brunt, often leading to bends or cracks. The deeper and sharper the pothole, the higher the risk of immediate damage or breakage.
5. Other common causes
-
High-speed cornering – increases lateral stress, which can deform wheels, especially with thin tires.
-
Poorly maintained roads – raised markings, iron covers, or surface irregularities can cause sudden impacts.
-
Incorrect tire pressure – underinflated tires offer less protection and increase the chance of wheel deformation.
Conclusion
Alloy wheel damage can come from multiple sources and always affects safety and performance. Professional restoration by Wheel Daddy partners can return wheels to their original condition, ensuring better safety, comfort, and appearance.
