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
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Citroen CX 20 TRE runs a 5x98 bolt pattern, 58.1mm center bore, and a 14x5.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 15x6.5J ET35, which tucks the tire under the fender lip on a stock-height Citroen CX 20 TRE. Our Maximum Aggressive reference is 16x7.0J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Citroen CX 20 TRE OE Wheel Specs
The 1983 Citroen CX 20 TRE (Fastback) uses a 5x98 bolt pattern with a 58.1mm center bore. Factory wheels are 14x5.5J 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 CX 20 TRE (1983) we drill the 5x98 pattern and cut the centre bore to 58.1mm 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 & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 14x5.5J ET45 → ~5.02″ backspacing
- Flush: 15x6.5J ET35 → ~5.13″ backspacing
- Max: 16x7.0J ET30 → ~5.18″ 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 CX 20 TRE? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Citroen CX 20 TRE use?
The 1983 Citroen CX 20 TRE uses a 5x98 bolt pattern.
How many lug bolts does the Citroen CX 20 TRE use?
The Citroen CX 20 TRE uses a 5-lug bolt pattern (5x98), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Citroen CX 20 TRE?
The Citroen CX 20 TRE's center bore is 58.1mm. 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 CX 20 TRE?
Factory wheels on the Citroen CX 20 TRE are 14x5.5J F/R.
What is the biggest wheel size I can fit on my Citroen CX 20 TRE without rubbing?
The most aggressive fitment we recommend without fender work is 16x7.0J at ET30 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 CX 20 TRE?
For a flush look with minimal to no rubbing, we recommend 15x6.5J at ET35 offset as a starting point on a stock or mildly lowered Citroen CX 20 TRE.
Do I need wheel spacers for my Citroen CX 20 TRE?
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 CX 20 TRE?
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 5.13" 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 CX 20 TRE?
The Citroen CX 20 TRE 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.
