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 vehicle this heavy, the wheel is a structural part before it is a styling part - it carries the load, the brake heat and the cornering forces all at once. A forged wheel buys back unsprung weight without giving up the load rating an SUV actually needs, which is the one number most cast aftermarket wheels quietly fall short on.
The Porsche Cayenne Turbo runs a 5x130 fitment, 71.6mm center bore, and a F: 18x8J wheel from the factory. Our Flush Fitment reference is F 21x10J ET50 / R 21x10J ET50, which tucks the tire under the fender lip on a stock-height Porsche Cayenne Turbo. Our Maximum Aggressive reference is F 22x10.5J ET40 / R 22x10.5J ET40 - beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Porsche Cayenne Turbo OE Wheel Specs
The 2008 Porsche Cayenne Turbo (SUV) uses a 5x130 bolt pattern with a 71.6mm center bore. Factory wheels are 18x8J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Porsche Cayenne Turbo (2008) we drill the 5x130 pattern and cut the centre bore to 71.6mm 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.

Real-World Fitment Notes
22x10J ET45 square, 295/30-22 Turbo big brakes - verify caliper/spoke clearance; 22in practical max; hubcentric rings if 74.1; 5x130. Verified via wheel-size.com/Element Wheels/Rennlist 957.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 18x8J ET50 → ~6.47″ F backspacing, R 18x8J ET50 → ~6.47″ R backspacing
- Flush: F 21x10J ET50 → ~7.47″ F backspacing, R 21x10J ET50 → ~7.47″ R backspacing
- Max: F 22x10.5J ET40 → ~7.32″ F backspacing, R 22x10.5J ET40 → ~7.32″ R backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Porsche spec, or want a wheel built to a custom offset for your Porsche Cayenne Turbo? 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 Porsche Cayenne Turbo use?
The 2008 Porsche Cayenne Turbo uses a 5x130 bolt pattern.
How many lug bolts does the Porsche Cayenne Turbo use?
The Porsche Cayenne Turbo uses a 5-lug bolt pattern (5x130), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Porsche Cayenne Turbo?
The Porsche Cayenne Turbo's center bore is 71.6mm. 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 Porsche Cayenne Turbo?
Factory wheels on the Porsche Cayenne Turbo are 18x8J F/R.
What is the biggest wheel size I can fit on my Porsche Cayenne Turbo without rubbing?
The most aggressive fitment we recommend without fender work is F 22x10.5J ET40 / R 22x10.5J ET40. 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 Porsche Cayenne Turbo?
For a flush look with minimal to no rubbing, we recommend F 21x10J ET50 / R 21x10J ET50 as a starting point on a stock or mildly lowered Porsche Cayenne Turbo.
Do I need wheel spacers for my Porsche Cayenne Turbo?
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 Porsche Cayenne Turbo?
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 7.47" backspacing up front and 7.47" 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 Porsche Cayenne Turbo?
Yes — the Porsche Cayenne Turbo'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.
