Steel Wheel Knowledge for B2B Buyers
This page explains common steel wheel specification terms that B2B buyers may need when sourcing steel wheels.
Understanding these terms can help buyers prepare clearer inquiries and reduce specification mismatch before quotation.
Common steel wheel specification terms include:
- Wheel size
- PCD / bolt pattern
- Center bore
- Offset / ET
- Finish
- MOQ
Wheel Size
Wheel size usually refers to the diameter and width of the wheel.
For example:
- 15 X 6
- 16 X 7
- 17 X 8
The first number usually refers to the wheel diameter. The second number usually refers to the wheel width.
Buyers should confirm the required size before ordering because different applications may require different diameter and width combinations.
PCD / Bolt Pattern
PCD means Pitch Circle Diameter. It is related to the bolt hole arrangement of the wheel.
Bolt pattern is one of the most important specifications when matching a steel wheel to a vehicle or application.
Examples may include:
- 5-114.3
- 5-120
- 6-139.7
- 8-165.1
Buyers should confirm the required PCD / bolt pattern before ordering.
Center Bore
Center bore refers to the center hole size of the wheel.
The correct center bore helps the wheel match the hub requirement of the target application.
Buyers should confirm the required center bore before ordering.
Offset / ET
Offset, also called ET, refers to the distance between the wheel mounting surface and the wheel center line.
Offset affects how the wheel sits in relation to the vehicle or application.
Buyers should confirm the required offset / ET before ordering because incorrect offset may cause fitment issues.
Finish
Finish refers to the surface color or coating of the wheel.
