Different agricultural rim types explained

Single-piece or multi-piece agricultural rims

The most important distinction between rims is shown in the size designation:

• x = single-piece rim
• – = multi-piece rim

A single-piece rim (x) is commonly used on tractors and agricultural machines that mainly operate in the field.

Multi-piece rims (–) are typically used in applications where easy maintenance or quick tyre changes are required, for example on machines with interchangeable wheel configurations.

Conclusion: single-piece rims are standard for most agricultural applications, while multi-piece rims are preferred when flexibility and serviceability are important.

W, DW and TW rim types explained

Agricultural rims are divided into three main rim profiles:

W-type rim

A standard agricultural rim with a single well.

Example: W 15L x 30

• W = rim profile code
• 15 = rim width (inch)
• L = flange height
• x = single-piece
• 30 = rim diameter (inch)

Conclusion: W rims are the standard choice for general agricultural use with standard tyre widths.

DW-type rim

A double well rim, designed for wider tyres and heavier machines.

Example: DW 14L x 20

• DW = double well
• 14 = rim width
• L = flange height
• x = single-piece
• 20 = rim diameter

Conclusion: DW rims provide more support and stability for wider tyres and higher loads.

TW-type rim

A triple well rim, used for very wide agricultural tyres.

Example: TW 23L x 38

• TW = triple well
• 23 = rim width
• L = flange height
• x = single-piece
• 38 = rim diameter

These rims are commonly used on machines such as self-propelled sprayers or high-capacity tractors.

Conclusion: TW rims are suitable for the widest tyres and the highest load requirements.
