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 Morgan Plus Four ships from the factory on a 5x114.3 bolt pattern with a 67.1mm center bore and a F 15x7J ET35 / R 15x7J ET35 wheel. Our flush reference for the Morgan Plus Four is 16x8J ET25.; our maximum aggressive reference is 17x8.5J ET20. — beyond that, expect clearance issues against the fender liner without further modification.
Morgan Plus Four OE Wheel Specs
The Morgan Plus Four ships from the factory on 5x114.3 bolt pattern wheels with a 67.1mm center bore. The stock wheel size is F 15x7J ET35 / R 15x7J ET35, 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 Morgan Plus Four (2025) we drill the 5x114.3 pattern and cut the centre bore to 67.1mm 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) | 15x7J | ET35 | 5.38 in (137 mm) | — | — |
| Flush | 16x8J | ET25 | 5.48 in (139 mm) | +3 mm | +23 mm |
| Maximum | 17x8.5J | ET20 | 5.54 in (141 mm) | +4 mm | +34 mm |
Vehicles With the Same Hub as the Morgan Plus Four (5x114.3, 67.1 mm Bore)
In our database, 456 other vehicle entries from 30 makes use exactly the same 5x114.3 bolt pattern and 67.1 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.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 35.2% of those also use a 67.1 mm center bore.
Hub-Centric Rings for a 67.1 mm Center Bore
A wheel with a center bore larger than 67.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 67.1 mm |
| 70.5 mm | 70.5 → 67.1 mm |
| 71.6 mm | 71.6 → 67.1 mm |
| 72.6 mm | 72.6 → 67.1 mm |
| 73.1 mm | 73.1 → 67.1 mm |
ANKUSI forged wheels are bored to exactly 67.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Morgan Plus Four use?
The 2025 Morgan Plus Four uses a 5x114.3 bolt pattern.
How many lug bolts does the Morgan Plus Four use?
The Morgan Plus Four uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Morgan Plus Four?
The Morgan Plus Four's center bore is 67.1mm. 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 does a flush wheel fitment look like on the Morgan Plus Four?
For a flush look with minimal to no rubbing, we recommend F 15x7J ET35 / R 15x7J ET35 as a starting point on a stock or mildly lowered Morgan Plus Four.
Do I need wheel spacers for my Morgan Plus Four?
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 Morgan Plus Four?
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 5.38" backspacing up front and 5.38" in the rear.
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 Morgan Plus Four?
Yes — the Morgan Plus Four's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
