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.

We publish the factory specification for the Rolls-Royce Cullinan I (RR31) below. We have not yet been able to verify aftermarket flush or maximum-aggressive offsets for this exact variant against a source we trust, so we are not listing any - an invented offset is worse than no offset when a wheel has to clear a caliper.

Rolls-Royce Cullinan I (RR31) OE Wheel Specs

The 2021 Rolls-Royce Cullinan I (RR31) (SUV) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are 22x8.5J 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 Rolls-Royce Cullinan I (RR31) (2021) we drill the 5x112 pattern and cut the centre bore to 66.6mm 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.

Aftermarket Fitment Data — Coming Soon

Published aftermarket fitment for this exact variant is still thin, so we have not committed to a flush or maximum-aggressive figure. Our engineering team is still collecting verified data for this variant. In the meantime the factory specification above is accurate and is the safe reference point for ordering.

Need a wheel for this car now? Contact ANKUSI with your target diameter, width and offset and our engineers will confirm the correct forged spec against your brake package before anything is cut. You can also use our Offset & Backspacing Calculator to work through the numbers yourself.

Custom Forged Wheels for the Rolls-Royce Cullinan I (RR31) (2021)

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 5x112 pattern and the 66.6mm 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.

Designs we already tool for the 5x112 pattern — each one is re-cut to your sizes and offsets:

Frequently Asked Questions

What bolt pattern (PCD) does the Rolls-Royce Cullinan I (RR31) use?
The 2021 Rolls-Royce Cullinan I (RR31) uses a 5x112 bolt pattern.
How many lug bolts does the Rolls-Royce Cullinan I (RR31) use?
The Rolls-Royce Cullinan I (RR31) uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Rolls-Royce Cullinan I (RR31)?
The Rolls-Royce Cullinan I (RR31)'s center bore is 66.6mm. 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 Rolls-Royce Cullinan I (RR31)?
Factory wheels on the Rolls-Royce Cullinan I (RR31) are 22x8.5J F/R.
Do I need wheel spacers for my Rolls-Royce Cullinan I (RR31)?
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.
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 Rolls-Royce Cullinan I (RR31)?
The Rolls-Royce Cullinan I (RR31) 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.
