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

The Citroen C3 Aircross's factory suspension tuning already accounts for a specific unsprung mass target. Forged construction lets ANKUSI match the factory strength spec while keeping rotational weight down, which is where the real handling benefit comes from on a taller, heavier SUV platform.

The Citroen C3 Aircross runs a 4x108 bolt pattern, 65.1mm center bore, and a 17x6.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x7.5J ET18, which tucks the tire under the fender lip on a stock-height Citroen C3 Aircross. Our Maximum Aggressive reference is 18x8.0J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.

Citroen C3 Aircross OE Wheel Specs

The 2025 Citroen C3 Aircross (SUV) uses a 4x108 bolt pattern with a 65.1mm center bore. Factory wheels are 17x6.5J F/R.

Why the factory spec works for most owners:

  • Balances ride comfort with everyday drivability
  • A commonly used size for this vehicle class, supporting parts and tire availability
  • Maintains clearance for the factory suspension and brake components
  • Provides stable, predictable handling across normal driving conditions

ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Citroen C3 Aircross (2025) 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 18x7.5J ET18 is the recommended starting point on a stock or mildly lowered Citroen C3 Aircross.

Maximum Aggressive Fitment

F/R 18x8.0J ET15 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: 17x6.5J ET23

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: 18x7.5J ET18

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 ET15

Cost: ~$5,500

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

Decision Guide

1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Citroen C3 Aircross owners.

Offset & Backspacing Reference

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

  • OE: 17x6.5J ET23 → ~4.66″ backspacing
  • Flush: 18x7.5J ET18 → ~4.96″ backspacing
  • Max: 18x8.0J ET15 → ~5.09″ 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 C3 Aircross? 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 C3 Aircross (2025)

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 18x7.5J ET18 flush setup and the 18x8.0J ET15 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 C3 Aircross use?
The 2025 Citroen C3 Aircross uses a 4x108 bolt pattern.
How many lug bolts does the Citroen C3 Aircross use?
The Citroen C3 Aircross 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 C3 Aircross?
The Citroen C3 Aircross'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 C3 Aircross?
Factory wheels on the Citroen C3 Aircross are 17x6.5J F/R.
What is the biggest wheel size I can fit on my Citroen C3 Aircross without rubbing?
The most aggressive fitment we recommend without fender work is 18x8.0J at ET15 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 C3 Aircross?
For a flush look with minimal to no rubbing, we recommend 18x7.5J at ET18 offset as a starting point on a stock or mildly lowered Citroen C3 Aircross.
Do I need wheel spacers for my Citroen C3 Aircross?
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 C3 Aircross?
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 4.96" 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 C3 Aircross?
The Citroen C3 Aircross 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.
