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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Ram 1500 Black Express ships from the factory on a 5x139.7 bolt pattern with a 77.8mm center bore and a 20x8J ET19 wheel. Our flush reference for the Ram 1500 Black Express is 20x9J ET0.; our maximum aggressive reference is 22x10J ET-12. — beyond that, expect clearance issues against the fender liner without further modification.
Ram 1500 Black Express OE Wheel Specs
The Ram 1500 Black Express ships from the factory on 5x139.7 bolt pattern wheels with a 77.8mm center bore. The stock wheel size is 20x8J ET19, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ram 1500 Black Express (2013) we drill the 5x139.7 pattern and cut the centre bore to 77.8mm 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.

Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 20x8J | ET19 | 5.25 in (133 mm) | — | — |
| Flush | 20x9J | ET0 | 5.00 in (127 mm) | −6 mm | +32 mm |
| Maximum | 22x10J | ET-12 | 5.03 in (128 mm) | −6 mm | +56 mm |
Vehicles With the Same Hub as the Ram 1500 Black Express (5x139.7, 77.8 mm Bore)
In our database, 27 other vehicle entries from 4 makes use exactly the same 5x139.7 bolt pattern and 77.8 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.
5x139.7 is used by 0.9% of the vehicle pages in our English fitment guide (56 of 6,503); 50.0% of those also use a 77.8 mm center bore.
Hub-Centric Rings for a 77.8 mm Center Bore
A wheel with a center bore larger than 77.8 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 78.1 mm | 78.1 → 77.8 mm |
| 84.1 mm | 84.1 → 77.8 mm |
| 93.1 mm | 93.1 → 77.8 mm |
| 100.1 mm | 100.1 → 77.8 mm |
ANKUSI forged wheels are bored to exactly 77.8 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Ram 1500 Black Express use?
The 2013 Ram 1500 Black Express uses a 5x139.7 bolt pattern.
How many lug bolts does the Ram 1500 Black Express use?
The Ram 1500 Black Express uses a 5-lug bolt pattern (5x139.7), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Ram 1500 Black Express?
The Ram 1500 Black Express's center bore is 77.8mm. 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 1500 Black Express?
Factory wheels on the Ram 1500 Black Express are 20x8J ET19.
What does a flush wheel fitment look like on the Ram 1500 Black Express?
For a flush look with minimal to no rubbing, we recommend 20x9J at ET0 offset as a starting point on a stock or mildly lowered Ram 1500 Black Express.
Do I need wheel spacers for my Ram 1500 Black Express?
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.
How do I calculate wheel backspacing for my Ram 1500 Black Express?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 5" of backspacing.
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 1500 Black Express?
The Ram 1500 Black Express 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.
