Looking for high-quality trailer parts, trailer rims, or trailer landing gear? CIMC Equilink supplies reliable semi-trailer accessories—including durable trailer rims and landing gear—for transport vehicles worldwide. Below, we share key details about trailer rims (wheels), their maintenance, and the advantages of aluminum alloy options.
Trailer Rims: Key Semi-Trailer Parts
Trailer rims (also called wheels) are critical trailer parts for semi-trailers—powerful transport vehicles known for heavy load capacity. It’s important to note: "rims" and "tires" are distinct components, each playing a vital role in safe transportation.
Our trailer rims are designed for durability and performance, fitting various semi-trailer types like 20′/30′ straight back container transport semi-trailers and flatbed semi-trailers.



Trailer Rim Maintenance Tips
Proper maintenance extends the life of your trailer rims. Follow these guidelines:
1. Let hot rims cool naturally before cleaning—never use cold water. Sudden temperature changes can damage aluminum alloy rims, warp brake discs, and reduce braking efficiency. Avoid high-temperature detergent (it causes discoloration).
2. Remove tough asphalt with a soft brush (not iron brushes) to prevent surface scratches.
3. Use paint thinner to clean dirt around scratches; for deep scratches, use a toothpick. Protect nearby areas with tape. Use professional, non-abrasive cleaners for stubborn stains—avoid paint brighteners or abrasive materials (rims have a protective metal film).
4. Apply decorative paint to damaged areas; let it dry slightly raised for easy inspection.
5. After the paint fully dries, smooth the surface with soapy water-dampened waterproof paper. Polish for shine and apply wax.
6. For deep scratches: If no metal is exposed, touch up with paint. If metal is visible, replace the rim to prevent rust.

Advantages of Aluminum Alloy Trailer Rims

Aluminum alloy trailer rims offer superior performance compared to ordinary iron rims:
1. Energy Saving & Heat Dissipation: Lighter weight reduces vehicle load and wheel rotational inertia, improving acceleration and reducing fuel consumption.
2. High Safety: Aluminum’s thermal conductivity is 3x that of steel/iron, quickly dissipating heat from tires and chassis. This lowers tire blowout risks and maintains braking efficiency during long high-speed drives or downhill braking.
3. Strong Load Capacity: Aluminum alloy rims have 5x the load capacity of iron rims. Forged aluminum rims deform only 5cm under 71,200 kg, while iron rims deform 5cm under just 13,600 kg.
4. Sleek & Durable Appearance: Aluminum’s fluidity in high temperatures enables versatile designs. Polishing, electroplating, and anti-corrosion/electrostatic powder coating keep rims looking new for years.
