How often should you replace your wheels?
Car Wheel Rim Replacement Guidelines
Car wheel rims are generally recommended for inspection and replacement every 4-5 years or after 40,000-60,000 kilometers of driving. The specific replacement interval should be determined based on the rim material, usage environment, and degree of wear.
Core Replacement Cycle
Under normal circumstances, the recommended replacement cycle for wheel rims is 4-5 years or 40,000-60,000 kilometers. However, the cycle should be shortened under the following conditions:
- Aluminum Alloy Rims: Special attention should be paid to internal deformation after 4 years.
- Steel Rims: If there is no obvious damage, the cycle can be extended to 5-6 years.
- Magnesium Alloy Rims: Professional inspection is required every year.

Key Replacement Criteria
The rim should be replaced immediately (regardless of service life) in the following situations:
- Bent or Deformed: Causes abnormal tire wear or steering wheel vibration.
- Cracks or Fractures: Commonly found on the inner side or around the valve stem area where stress is concentrated.
- Severe Corrosion: Rust depth exceeds 0.5mm or there are perforations.
- Edge Bulging: Affects tire sealing and may cause air leakage.

Influencing Factors
- Material Differences:
- Aluminum Alloy Rims: Pay attention to salt spray corrosion in coastal areas; recommended replacement interval should be shortened by 1/4.
- Steel Rims: Strong impact resistance but require rust protection.
- Magnesium Alloy Rims: Do not use alkaline car wash detergents.
- Road Conditions:
- Urban Paved Roads: Reference the upper limit of 60,000 kilometers.
- Unpaved Roads: Inspection is recommended at the lower limit of 40,000 kilometers.
- Speed Bumps/Potholes: Pass at speeds ≤ 20 km/h.
- Driving Habits:
- Sudden Braking/Sharp Turns: Impact force is three times higher than normal.
- Frequent Overloading: For every 20% overload, service life is reduced by 30%.
