2. Accurate measurement method of wheel hub hole distance
Hub hole pitch (PCD, Pitch Circle Diameter) is an important parameter for wheel hub installation. Inaccurate measurement will lead to failure to install. The following are detailed measurement steps:
Step 1: Confirm the number of holes
First, count the number of bolt holes in the wheel hub. Common ones include 4 holes, 5 holes, 6 holes, etc.
Step 2: Measurement Method
| Number of holes | Measurement method |
|---|---|
| 4 holes | Directly measure the center distance between two diagonal holes |
| 5 holes | Measure the center distance between any two adjacent holes × 1.051 |
| 6 holes | Measure the center distance between the two diagonal holes × 0.866 |
Step 3: Use professional tools
It is recommended to use vernier calipers or hole distance measuring ruler to ensure measurement accuracy. Ordinary rulers have larger measurement errors.
3. Reference table of wheel hub hole distances for common vehicle models
| Model brand | Common hole spacing | Center hole diameter |
|---|---|---|
| public | 5×112 | 57.1mm |
| toyota | 5×114.3 | 60.1mm |
| BMW | 5×120 | 72.6mm |
| Honda | 4×100 | 56.1mm |
4. Measurement precautions
1.Clean wheel hub: Dirt and rust on the wheel hub surface need to be removed before measurement
2.multiple measurements: It is recommended to measure at least 3 times and take the average
3.Record data: Simultaneously record the center hole diameter and offset (ET value)
4.Consulting major: If you are not sure, you can ask the modification shop or 4S shop for confirmation.
5. Answers to popular modification questions
Q: Can I force installation if the hole spacing is wrong?
A: Absolutely not! This will cause uneven stress on the screws, posing serious safety hazards.
Q: Can wheel hubs with different hole spacing be modified?
A: It can be converted through a reducing flange, but it needs to be operated by a professional modification shop.
Q: What is the allowable range of measurement error?
A: Generally, it does not exceed ±0.5mm. If it exceeds, the wheel hub must be replaced.
6. Observation of the latest modification trends
According to recent hot discussions, lightweight wheels and personalized customization have become mainstream trends. The data shows:
| trend | Attention grows | Represent the brand |
|---|---|---|
| Forged wheels | 45% | BBS,RAYS |
| Spin technology | 32% | ENKEI,OZ |
| Custom painting | 28% | HRE, VOSSEN |
Correctly measuring the wheel hub hole distance is the basis for modification. I hope this article can help you perform wheel hub modification safely and professionally. It is recommended to learn more about local regulations before modification and choose products and services from formal channels.
