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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The MG EP ships from the factory on a 5x112 bolt pattern with a 57.1mm center bore and a 16x6.5J ET41 wheel. Our flush reference for the MG EP is 17x7.5J ET35.; our maximum aggressive reference is 18x8J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
MG EP OE Wheel Specs
The MG EP ships from the factory on 5x112 bolt pattern wheels with a 57.1mm center bore. The stock wheel size is 16x6.5J ET41, 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 MG EP (2025) we drill the 5x112 pattern and cut the centre bore to 57.1mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.

Offset & Backspacing Reference
Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.
- OE 16x6.5J ET41: backspacing ≈ 5.36"
- Flush 17x7.5J ET35: backspacing ≈ 5.63"
- Max 18x8J ET35: backspacing ≈ 5.88"

Vehicles With the Same Hub as the MG EP (5x112, 57.1 mm Bore)
In our database, 407 other vehicle entries from 18 makes use exactly the same 5x112 bolt pattern and 57.1 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.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 29.0% of those also use a 57.1 mm center bore.
Hub-Centric Rings for a 57.1 mm Center Bore
A wheel with a center bore larger than 57.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 57.1 mm |
| 63.4 mm | 63.4 → 57.1 mm |
| 64.1 mm | 64.1 → 57.1 mm |
| 65.1 mm | 65.1 → 57.1 mm |
| 73.1 mm | 73.1 → 57.1 mm |
ANKUSI forged wheels are bored to exactly 57.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the MG EP use?
The 2025 MG EP uses a 5x112 bolt pattern.
How many lug bolts does the MG EP use?
The MG EP uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the MG EP?
The MG EP's center bore is 57.1mm. 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 MG EP?
For a flush look with minimal to no rubbing, we recommend 17x7.5J at ET35 offset as a starting point on a stock or mildly lowered MG EP.
Do I need wheel spacers for my MG EP?
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 MG EP?
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 5.63" 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 MG EP?
The MG EP 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.
