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

Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.

The Citroen C4 runs a 4x108 bolt pattern, 65.1mm center bore, and a 16x6.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x7.5J ET20, which tucks the tire under the fender lip on a stock-height Citroen C4. Our Maximum Aggressive reference is 18x8.0J ET18 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.

Citroen C4 OE Wheel Specs

The 2009 Citroen C4 (Hatchback) uses a 4x108 bolt pattern with a 65.1mm center bore. Factory wheels are 16x6.5J F/R.

Why the factory spec works for most owners:

Preserves the factory-tuned ride and steering feel
A mainstream size for this segment, keeping tire choice wide and prices reasonable
Leaves full clearance for the stock brakes and suspension hardware
Keeps handling predictable and consistent in everyday conditions

ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Citroen C4 (2009) we drill the 4x108 pattern and cut the centre bore to 65.1mm 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.

Flush Fitment

For a flush look with minimal rubbing, F/R 17x7.5J ET20 is the recommended starting point on a stock or mildly lowered Citroen C4.

Maximum Aggressive Fitment

F/R 18x8.0J ET18 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.

Case 1: Daily Driver (Factory-Style)

Profile: Everyday driving, prioritizes comfort and low running cost.

Setup: 16x6.5J ET27

Cost: ~$620

Outcome: Minimal visual change, ride and fuel economy essentially unaffected.

Case 2: Balanced Enthusiast (Balanced / Flush Fit)

Profile: Wants a sportier stance without sacrificing daily usability.

Setup: 17x7.5J ET20

Cost: ~$3,000

Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.

Case 3: Show Build (Max Aggressive)

Profile: Built primarily for shows or occasional track/show use.

Setup: 18x8.0J ET18

Cost: ~$5,500

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.

Decision Guide

What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.

What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.

How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Citroen C4 owners.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

OE: 16x6.5J ET27 → ~4.81″ backspacing
Flush: 17x7.5J ET20 → ~5.04″ backspacing
Max: 18x8.0J ET18 → ~5.21″ backspacing

Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Citroen spec, or want a wheel built to a custom offset for your Citroen C4? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Custom Forged Wheels for the Citroen C4 (2009)

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 4x108 pattern and the 65.1mm 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 — most Citroen orders on this platform land somewhere between the 17x7.5J ET20 flush setup and the 18x8.0J ET18 aggressive setup referenced above.

We do not hold 4x108 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.

Frequently Asked Questions

What bolt pattern (PCD) does the Citroen C4 use?

The 2009 Citroen C4 uses a 4x108 bolt pattern.

How many lug bolts does the Citroen C4 use?

The Citroen C4 uses a 4-lug bolt pattern (4x108), so you need a 4-lug forged wheel to bolt straight on.

What is the center bore size on the Citroen C4?

The Citroen C4's center bore is 65.1mm. 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 size are the factory (stock) wheels on the Citroen C4?

Factory wheels on the Citroen C4 are 16x6.5J F/R.

What is the biggest wheel size I can fit on my Citroen C4 without rubbing?

The most aggressive fitment we recommend without fender work is 18x8.0J at ET18 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.

What does a flush wheel fitment look like on the Citroen C4?

For a flush look with minimal to no rubbing, we recommend 17x7.5J at ET20 offset as a starting point on a stock or mildly lowered Citroen C4.

Do I need wheel spacers for my Citroen C4?

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 Citroen C4?

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 5.04" 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 Citroen C4?

The Citroen C4 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.
