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 Alfa Romeo 159's factory wheel spec reflects a deliberate balance between comfort, steering feel and durability that the engineering team tuned for. Forging lets ANKUSI match that same strength target while trimming rotational mass — the part of a wheel upgrade that actually changes how the car drives, not just how it looks.
The Alfa Romeo 159 runs a 5x110 bolt pattern, 65.1mm center bore, and a 16x7.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.5J ET35, which tucks the tire under the fender lip on a stock-height Alfa Romeo 159. Our Maximum Aggressive reference is 19x9.0J ET32 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Alfa Romeo 159 OE Wheel Specs
The 2005 Alfa Romeo 159 (Sedan) uses a 5x110 bolt pattern with a 65.1mm center bore. Factory wheels are 16x7.0J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Alfa Romeo 159 (2005) we drill the 5x110 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 16x7.0J ET41 → ~5.61″ backspacing
- Flush: 18x8.5J ET35 → ~6.13″ backspacing
- Max: 19x9.0J ET32 → ~6.26″ 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 Alfa Romeo spec, or want a wheel built to a custom offset for your Alfa Romeo 159? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Alfa Romeo 159: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2005 | 5x110 | 65.1 mm | 16x7J |
| 2009 | 5x110 | 65.1 mm | 16x7J |
Bolt pattern and center bore stay the same across all 2 model years in our database (2005–2009).
Vehicles With the Same Hub as the Alfa Romeo 159 (5x110, 65.1 mm Bore)
In our database, 139 other vehicle entries from 19 makes use exactly the same 5x110 bolt pattern and 65.1 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.
5x110 is used by 2.2% of the vehicle pages in our English fitment guide (145 of 6,503); 96.6% of those also use a 65.1 mm center bore.
Hub-Centric Rings for a 65.1 mm Center Bore
A wheel with a center bore larger than 65.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.1 mm | 66.1 → 65.1 mm |
| 66.6 mm | 66.6 → 65.1 mm |
| 67.1 mm | 67.1 → 65.1 mm |
| 70.1 mm | 70.1 → 65.1 mm |
| 73.1 mm | 73.1 → 65.1 mm |
ANKUSI forged wheels are bored to exactly 65.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Alfa Romeo 159 use?
The 2005 Alfa Romeo 159 uses a 5x110 bolt pattern.
How many lug bolts does the Alfa Romeo 159 use?
The Alfa Romeo 159 uses a 5-lug bolt pattern (5x110), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Alfa Romeo 159?
The Alfa Romeo 159'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 Alfa Romeo 159?
Factory wheels on the Alfa Romeo 159 are 16x7.0J F/R.
What is the biggest wheel size I can fit on my Alfa Romeo 159 without rubbing?
The most aggressive fitment we recommend without fender work is 19x9.0J at ET32 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 Alfa Romeo 159?
For a flush look with minimal to no rubbing, we recommend 18x8.5J at ET35 offset as a starting point on a stock or mildly lowered Alfa Romeo 159.
Do I need wheel spacers for my Alfa Romeo 159?
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 Alfa Romeo 159?
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 6.13" 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 Alfa Romeo 159?
The Alfa Romeo 159 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.
