The service life of car wheels typically ranges from 5 to 10 years, with the specific duration depending on the material, usage environment, and maintenance conditions. Due to their lightweight and high-strength properties, aluminum alloy wheels are generally more durable than steel wheels. Under good road conditions and standard driving practices, they can last over 8 years, while steel wheels may need to be inspected and replaced around 6 years. High-salt air in coastal areas or de-icing salts in cold regions may also intensify corrosion. If edge wear, structural cracks, or obvious deformation are found on the wheels, they should be replaced immediately to ensure tyre airtightness and driving safety. It is best to check the wheel condition every 6 months. Avoid washing aluminum alloy wheels with cold water when they are hot. Minor scratches can be repaired with special paint, but if the metal layer is exposed, replacement is necessary. When modifying wheels, choose products that meet safety certifications, as inferior products may risk cracking within 3 years.
