When replacing a 10-stud truck wheel, one of the most important details to confirm is whether the truck requires a 10/285 or 10/335 wheel. Both configurations have 10 mounting holes, so simply counting the studs is not enough to identify the correct fitment.
The difference is the Pitch Circle Diameter (PCD). A 10/285 wheel has its mounting holes positioned on a 285 mm pitch circle, while a 10/335 wheel uses a 335 mm pitch circle.
Mesh Wheels and Accessories offers 22.5-inch truck wheels in both configurations across selected sizes, materials and applications.
This guide focuses on how to identify which PCD your truck requires and the other specifications you should confirm before ordering.
Why 10 Studs Doesn't Tell You the Wheel Fitment
Seeing 10 studs or mounting holes can narrow down your search, but it does not provide the complete bolt pattern.
Two wheels can both have:
- 10 mounting holes
- A 22.5-inch diameter
- A similar overall appearance
and still have completely different PCDs.
This is why a replacement should not be ordered simply as a “10-stud 22.5-inch truck wheel.”
You need to know which 10-stud configuration the vehicle requires.
What Is a 10/285 Truck Wheel?
A 10/285 truck wheel has:
10 mounting holes positioned around a 285 mm Pitch Circle Diameter.
Within the Mesh range, 10/285 wheels are commonly associated with American truck applications.
Selected 10/285 configurations are available across different 22.5-inch wheel sizes.
However, identifying your truck as American does not automatically confirm that it requires a 10/285 wheel.
The actual vehicle and wheel specifications should always be checked.
What Is a 10/335 Truck Wheel?
A 10/335 truck wheel also has 10 mounting holes, but they are positioned around a 335 mm Pitch Circle Diameter.
Within the Mesh range, this configuration is commonly associated with European and Japanese truck applications.
As with 10/285, vehicle origin should only be treated as a useful starting point.
The required PCD should be confirmed from the truck, hub or existing wheel specifications before purchasing a replacement.
10/285 vs 10/335: Quick Comparison
Although the names look similar, these are two different mounting patterns.
| Specification | 10/285 | 10/335 |
|---|---|---|
| Number of mounting holes | 10 | 10 |
| PCD | 285 mm | 335 mm |
| Common association within Mesh range | American applications | European/Japanese applications |
| Same bolt pattern? | No | No |
| Interchangeable based on PCD? | No | No |
The key difference is the 50 mm difference in Pitch Circle Diameter.
That changes where the mounting holes are positioned around the wheel.
How Do I Know If My Truck Is 10/285 or 10/335?
There are several pieces of information you can use to identify the required wheel.
Check the Existing Wheel
Start by looking for markings, specifications or a part number on the existing truck wheel.
Record any information you can find.
This may help identify the original wheel without relying entirely on manual measurements.
Check the Vehicle Specifications
The vehicle's wheel and hub specifications may identify the required mounting configuration.
Use information for the exact model and configuration rather than assuming all trucks from one manufacturer use the same PCD.
Check the Existing Hub and Mounting Arrangement
The hub and existing wheel can provide further information when the PCD is not clearly marked.
Because accurate wheel fitment is important, have the mounting specification checked if you cannot confidently identify it.
Provide Photos and Specifications
If you're making an enquiry about a replacement, provide clear photographs of the wheel, hub and any visible markings alongside the truck details.
The more information available, the easier it is to narrow down the correct wheel.
Can You Tell 10/285 and 10/335 Apart by Looking at Them?
The difference in mounting-hole spacing may be visible when the wheels are compared, but visual appearance should not be relied on as the final fitment check.
Both configurations have 10 mounting holes and can be found on large commercial truck wheels.
A photograph can help with identification, but confirmed specifications are more reliable than estimating PCD by eye.
Can I Identify the PCD From the Truck Brand?
Truck brand can provide a clue, but it should not be used as the only method of identifying wheel fitment.
Within the Mesh range:
10/285 is commonly associated with American truck applications.
10/335 is commonly associated with European and Japanese truck applications.
Individual trucks can vary by model, axle, year and configuration.
Modifications or replacement hubs may also mean that assumptions based on the badge on the front of the truck are unreliable.
Confirm the actual mounting specification.
Does 22.5-Inch Wheel Size Tell Me the PCD?
No.
22.5 inches refers to the nominal wheel diameter.
It does not tell you the PCD.
For example, Mesh's range includes selected 22.5-inch truck wheels in both:
- 10/285
- 10/335
The same applies to wheel width.
Two wheels could both be 8.25 × 22.5 while using different PCD configurations.
Does Wheel Width Tell Me If It Is 10/285 or 10/335?
No.
Wheel width and PCD are independent specifications.
Within the Mesh range, 22.5-inch wheels are available across widths including:
- 8.25 × 22.5
- 9.00 × 22.5
- 11.75 × 22.5
Selected configurations are available across 10/285 and 10/335 applications.
So seeing 8.25 × 22.5 stamped on the wheel does not by itself tell you which PCD the wheel uses.
What Else Do I Need to Check Besides PCD?
Determining whether you need 10/285 or 10/335 is important, but it is only one step.
Once the PCD is known, check the rest of the wheel specification.
Wheel Diameter
Confirm the required diameter, such as 22.5 inches.
Wheel Width
Determine whether you need an 8.25, 9.00, 11.75-inch or another specified width.
Centre Bore
Check the required wheel centre bore and hub specification.
Offset
Confirm the correct truck wheel offset, as different offsets affect wheel positioning.
Stud-Hole Specification
Check the individual mounting-hole requirements rather than relying only on PCD.
Load Rating
Make sure the wheel has the appropriate rated capacity for the application.
Axle Application
Identify whether the replacement is required for a steer, drive or trailer position.
Example: Two 8.25 × 22.5 Wheels
Suppose you are comparing two wheels and both are marked:
8.25 × 22.5
At first glance, they may appear to be the same size.
But one could be:
8.25 × 22.5 – 10/285
while another could be:
8.25 × 22.5 – 10/335
The width and diameter match, but the PCD does not.
Even after identifying the correct PCD, you would still need to check specifications such as centre bore, offset, mounting configuration and load rating.
This demonstrates why the complete wheel specification matters.
Can You Fit a 10/285 Wheel on a 10/335 Hub?
A 10/285 wheel and 10/335 wheel use different PCDs.
Their mounting holes are positioned on different diameter circles, so they should not be treated as interchangeable wheel patterns.
If your truck requires a 10/335 configuration, select a wheel that meets the required 10/335 specification.
Likewise, a vehicle requiring 10/285 needs the appropriate 10/285 wheel specification.
Common Mistakes When Identifying 10-Stud Truck Wheels
Avoid these common assumptions:
- All 10-stud truck wheels are the same.
- All American trucks use 10/285.
- All European trucks use 10/335.
- All Japanese trucks use 10/335.
- Every 22.5-inch wheel has the same PCD.
- Wheel width determines the PCD.
- Counting 10 studs is enough to order a wheel.
- Matching PCD guarantees the rest of the wheel specification is correct.
Use the truck's actual wheel and hub requirements rather than relying on general assumptions.
What Information Should I Send When Enquiring About a Wheel?
If you're unsure whether your truck needs 10/285 or 10/335 wheels, gather as much information as possible before making an enquiry.
Useful details include:
- Truck make
- Truck model
- Vehicle configuration
- Wheel size
- Existing wheel markings
- Existing wheel part number
- Number of mounting holes
- PCD if known
- Centre bore if known
- Offset if known
- Steer, drive or trailer position
- Clear photographs of the wheel
- Clear photographs of identifying markings
This can make it easier to narrow down the appropriate replacement.
Frequently Asked Questions
How do I know if my truck wheels are 10/285 or 10/335?
