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
Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Jeep CJ-5 ships from the factory on a 5x139.7 bolt pattern with a 108mm center bore and a 15x5.5J ET12 wheel. Our flush reference for the Jeep CJ-5 is 15x7J ET0.; our maximum aggressive reference is 15x8J ET-12. — beyond that, expect clearance issues against the fender liner without further modification.
Jeep CJ-5 OE Wheel Specs
The Jeep CJ-5 ships from the factory on 5x139.7 bolt pattern wheels with a 108mm center bore. The stock wheel size is 15x5.5J ET12, 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 Jeep CJ-5 (1955) we drill the 5x139.7 pattern and cut the centre bore to 108mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
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) | 15x5.5J | ET12 | 3.72 in (95 mm) | — | — |
| Flush | 15x7J | ET0 | 4.00 in (102 mm) | +7 mm | +31 mm |
| Maximum | 15x8J | ET-12 | 4.03 in (102 mm) | +8 mm | +56 mm |
Vehicles With the Same Hub as the Jeep CJ-5 (5x139.7, 108 mm Bore)
In our database, 19 other Jeep entries use exactly the same 5x139.7 bolt pattern and 108 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); 35.7% of those also use a 108 mm center bore.
Hub-Centric Rings for a 108 mm Center Bore
A wheel with a center bore larger than 108 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 108.1 mm | 108.1 → 108 mm |
| 110.1 mm | 110.1 → 108 mm |
| 130.1 mm | 130.1 → 108 mm |
ANKUSI forged wheels are bored to exactly 108 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Jeep CJ-5 use?
The 1955 Jeep CJ-5 uses a 5x139.7 bolt pattern.
How many lug bolts does the Jeep CJ-5 use?
The Jeep CJ-5 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 Jeep CJ-5?
The Jeep CJ-5's center bore is 108mm. 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 Jeep CJ-5?
Factory wheels on the Jeep CJ-5 are 15x5.5J ET12.
What does a flush wheel fitment look like on the Jeep CJ-5?
For a flush look with minimal to no rubbing, we recommend 15x7J at ET0 offset as a starting point on a stock or mildly lowered Jeep CJ-5.
Do I need wheel spacers for my Jeep CJ-5?
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 Jeep CJ-5?
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 4" 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 Jeep CJ-5?
The Jeep CJ-5 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.
