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
On a supercar, wheel weight is one of the few remaining places to cut rotational mass without touching the powertrain or chassis the factory already optimized. Forging gets there at the same structural margin as the OE wheel, which is exactly the trade a car built around outright performance rewards.
The Ferrari 550 Maranello runs a 5x108 bolt pattern, 67.1mm center bore, and a F: 18x8.5J wheel from the factory. Our Flush Fitment reference is F 18x9.0J ET38 / R 18x11.5J ET30, which tucks the tire under the fender lip on a stock-height Ferrari 550 Maranello. Our Maximum Aggressive reference is F 19x9.5J ET32 / R 19x12.0J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ferrari 550 Maranello OE Wheel Specs
The 2001 Ferrari 550 Maranello (Grand Tourer) uses a 5x108 bolt pattern with a 67.1mm center bore. Factory wheels are F: 18x8.5J R: 18x10.5J.
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 Ferrari 550 Maranello (2001) we drill the 5x108 pattern and cut the centre bore to 67.1mm 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 18x9.0J ET38 / R 18x11.5J ET30 is the recommended starting point on a stock or mildly lowered Ferrari 550 Maranello.
Maximum Aggressive Fitment
F 19x9.5J ET32 / R 19x12.0J ET25 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 18x8.5J ET43 → ~6.44″ F backspacing, R 18x10.5J ET38 → ~7.25″ R backspacing
- Flush: F 18x9.0J ET38 → ~6.5″ F backspacing, R 18x11.5J ET30 → ~7.43″ R backspacing
- Max: F 19x9.5J ET32 → ~6.51″ F backspacing, R 19x12.0J ET25 → ~7.48″ 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 Ferrari spec, or want a wheel built to a custom offset for your Ferrari 550 Maranello? 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 Ferrari 550 Maranello (2001)
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 5x108 pattern and the 67.1mm 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.

What bolt pattern (PCD) does the Ferrari 550 Maranello use?
The 2001 Ferrari 550 Maranello uses a 5x108 bolt pattern.
How many lug bolts does the Ferrari 550 Maranello use?
The Ferrari 550 Maranello uses a 5-lug bolt pattern (5x108), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Ferrari 550 Maranello?
The Ferrari 550 Maranello's center bore is 67.1mm. 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 Ferrari 550 Maranello?
Factory wheels on the Ferrari 550 Maranello are F: 18x8.5J R: 18x10.5J.
What is the biggest wheel size I can fit on my Ferrari 550 Maranello without rubbing?
The most aggressive fitment we recommend without fender work is F 19x9.5J ET32 / R 19x12.0J 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 Ferrari 550 Maranello?
For a flush look with minimal to no rubbing, we recommend F 18x9.0J ET38 / R 18x11.5J ET30 as a starting point on a stock or mildly lowered Ferrari 550 Maranello.
Do I need wheel spacers for my Ferrari 550 Maranello?
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 Ferrari 550 Maranello?
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 6.5" backspacing up front and 7.43" 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 Ferrari 550 Maranello?
Yes — the Ferrari 550 Maranello'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.
Vehicles With the Same Hub as the Ferrari 550 Maranello (5x108, 67.1 mm Bore)
In our database, 33 other vehicle entries from 5 makes use exactly the same 5x108 bolt pattern and 67.1 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.
5x108 is used by 7.5% of the vehicle entries in our database (479 of 6,396); 7.1% of those also use a 67.1 mm center bore.
Hub-Centric Rings for a 67.1 mm Center Bore
A wheel with a center bore larger than 67.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 67.1 mm |
| 70.5 mm | 70.5 → 67.1 mm |
| 71.6 mm | 71.6 → 67.1 mm |
| 72.6 mm | 72.6 → 67.1 mm |
| 73.1 mm | 73.1 → 67.1 mm |
ANKUSI forged wheels are bored to exactly 67.1 mm for this vehicle, so no ring is needed.
