This question involves multiple considerations, including vehicle appearance, safety, and cost. Scratches not only affect the car's appearance but can also lead to oxidation and corrosion, potentially reducing the wheel's lifespan. If left untreated for a long time, scratches could result in more serious issues, such as tire leaks or vehicle instability.
Various mature repair techniques are available in the market that can nearly restore the wheel to its original condition, making repair a more economical choice than buying a new wheel. However, if the scratch is severe, DIY repair might not fully address the issue and could even pose safety risks. In such cases, it is advisable to replace the wheel with a new one to ensure stability and safety.
Timely repair of wheel scratches is crucial to maintaining the vehicle's appearance, extending the wheel's lifespan, and ensuring safe driving. For minor scratches, self-repair can be considered, while for severe damage, replacing the wheel is the wiser choice to avoid potential safety hazards. Therefore, from the perspectives of aesthetics, vehicle safety, and durability, repairing scratches on car wheels is indeed necessary.
