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
SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.
The Alfa Romeo Stelvio Quadrifoglio runs a 5x110 bolt pattern, 65.1mm center bore, and a F: 20x9.0J wheel from the factory. Our Flush Fitment reference is F 21x9.5J ET25 / R 21x10.5J ET30, which tucks the tire under the fender lip on a stock-height Alfa Romeo Stelvio Quadrifoglio. Our Maximum Aggressive reference is F 22x10.0J ET20 / R 22x11.0J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Alfa Romeo Stelvio Quadrifoglio OE Wheel Specs
The 2020 Alfa Romeo Stelvio Quadrifoglio (SUV) uses a 5x110 bolt pattern with a 65.1mm center bore. Factory wheels are F: 20x9.0J R: 20x10.0J.
Why the factory spec works for most owners:
- Keeps the factory ride quality and noise levels intact
- A common fitment for this class, so replacement tires are easy to source
- Preserves clearance around the OE brakes and suspension geometry
- Delivers predictable, easy-to-live-with handling for daily use
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Alfa Romeo Stelvio Quadrifoglio (2020) 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x9.0J ET29 → ~6.14″ F backspacing, R 20x10.0J ET33 → ~6.8″ R backspacing
- Flush: F 21x9.5J ET25 → ~6.23″ F backspacing, R 21x10.5J ET30 → ~6.93″ R backspacing
- Max: F 22x10.0J ET20 → ~6.29″ F backspacing, R 22x11.0J ET25 → ~6.98″ R 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 Stelvio Quadrifoglio? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Alfa Romeo Stelvio Quadrifoglio: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2018 | 5x110 | 65.1 mm | 20x9J |
| 2020 | 5x110 | 65.1 mm | 20x9J |
Bolt pattern and center bore stay the same across all 2 model years in our database (2018–2020).
Vehicles With the Same Hub as the Alfa Romeo Stelvio Quadrifoglio (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 Stelvio Quadrifoglio use?
The 2020 Alfa Romeo Stelvio Quadrifoglio uses a 5x110 bolt pattern.
How many lug bolts does the Alfa Romeo Stelvio Quadrifoglio use?
The Alfa Romeo Stelvio Quadrifoglio 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 Stelvio Quadrifoglio?
The Alfa Romeo Stelvio Quadrifoglio'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 Stelvio Quadrifoglio?
Factory wheels on the Alfa Romeo Stelvio Quadrifoglio are F: 20x9.0J R: 20x10.0J.
What is the biggest wheel size I can fit on my Alfa Romeo Stelvio Quadrifoglio without rubbing?
The most aggressive fitment we recommend without fender work is F 22x10.0J ET20 / R 22x11.0J ET25. 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 Stelvio Quadrifoglio?
For a flush look with minimal to no rubbing, we recommend F 21x9.5J ET25 / R 21x10.5J ET30 as a starting point on a stock or mildly lowered Alfa Romeo Stelvio Quadrifoglio.
Do I need wheel spacers for my Alfa Romeo Stelvio Quadrifoglio?
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 Stelvio Quadrifoglio?
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 6.23" backspacing up front and 6.93" in the rear.
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 Stelvio Quadrifoglio?
Yes — the Alfa Romeo Stelvio Quadrifoglio's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
