Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |

| Flush Fitment | 20x9.0J at ET30 offset |
| Maximum Aggressive | 21x9.5J at ET25 offset |
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 Stelvio'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 Alfa Romeo Stelvio runs a 5x110 bolt pattern, 65.1mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET30, which tucks the tire under the fender lip on a stock-height Alfa Romeo Stelvio. Our Maximum Aggressive reference is 21x9.5J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Alfa Romeo Stelvio OE Wheel Specs
The 2018 Alfa Romeo Stelvio (SUV) uses a 5x110 bolt pattern with a 65.1mm center bore. Factory wheels are 18x8.0J F/R.
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
Flush Fitment
For a flush look with minimal rubbing, F/R 20x9.0J ET30 is the recommended starting point on a stock or mildly lowered Alfa Romeo Stelvio.
Maximum Aggressive Fitment
F/R 21x9.5J ET25 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8.0J ET34 → ~5.84″ backspacing
- Flush: 20x9.0J ET30 → ~6.18″ backspacing
- Max: 21x9.5J ET25 → ~6.23″ 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? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
