How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
On a performance-oriented coupe, the wheel is one of the few components where shaving weight has a compounding effect - less rotational mass means less work for the brakes, the drivetrain, and the chassis on every input. A forged wheel gets there without compromising the strength margin the factory engineered in.
We publish the factory specification for the Ram 3500 below. We have not yet been able to verify aftermarket flush or maximum-aggressive offsets for this exact variant against a source we trust, so we are not listing any - an invented offset is worse than no offset when a wheel has to clear a caliper.
Ram 3500 OE Wheel Specs
The 2018 Ram 3500 (Pickup) uses a 8x165.1 bolt pattern with a 121.3mm center bore. Factory wheels are 17x6J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ram 3500 (2018) we drill the 8x165.1 pattern and cut the centre bore to 121.3mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Aftermarket Fitment: Confirmed on Request
Published aftermarket fitment for this exact variant is still thin, so we have not committed to a flush or maximum-aggressive figure. Our engineering team is still collecting verified data for this variant. In the meantime the factory specification above is accurate and is the safe reference point for ordering.
What we do know: Generation DS/DJ, model years 2011-2018. Verified against two independent fitment references.
Need a wheel for this car now? Contact ANKUSI with your target diameter, width and offset and our engineers will confirm the correct forged spec against your brake package before anything is cut. You can also use our Offset & Backspacing Calculator to work through the numbers yourself.
Custom Forged Wheels for the Ram 3500 (2018)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 8x165.1 pattern and the 121.3mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.

What bolt pattern (PCD) does the Ram 3500 use?
The 2018 Ram 3500 uses a 8x165.1 bolt pattern.
How many lug bolts does the Ram 3500 use?
The Ram 3500 uses a 8-lug bolt pattern (8x165.1), so you need a 8-lug forged wheel to bolt straight on.
What is the center bore size on the Ram 3500?
The Ram 3500's center bore is 121.3mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Ram 3500?
Factory wheels on the Ram 3500 are 17x6J F/R.
Do I need wheel spacers for my Ram 3500?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Ram 3500?
The Ram 3500 runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
Vehicles With the Same Hub as the Ram 3500 (8x165.1, 121.3 mm Bore)
In our database, 6 other vehicle entries from 2 makes use exactly the same 8x165.1 bolt pattern and 121.3 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
8x165.1 is used by 0.4% of the vehicle pages in our English fitment guide (29 of 6,503); 27.6% of those also use a 121.3 mm center bore.
Ram 3500: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2011 | 8x165.1 | 121.3 mm | 17x6J |
| 2018 | 8x165.1 | 121.3 mm | 17x6J |
| 2019 | 8x165.1 | 121.3 mm | 18x8J |
| 2025 | 8x200 | 142.1 mm | 17x6J |
| 2026 | 8x165.1 | 121.3 mm | 18x8J |
Check the model year before ordering: the specs change — bolt pattern 8x165.1 → 8x200 from 2025; center bore 121.3 mm → 142.1 mm from 2025; bolt pattern 8x200 → 8x165.1 from 2026; center bore 142.1 mm → 121.3 mm from 2026.
Hub-Centric Rings for a 121.3 mm Center Bore
A wheel with a center bore larger than 121.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 121.3 mm |
ANKUSI forged wheels are bored to exactly 121.3 mm for this vehicle, so no ring is needed.
