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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Bentley Arnage Blue Train Series runs a 5x120 bolt pattern, 72.6mm center bore, and a F: 19x8.5J wheel from the factory. Our Flush Fitment reference is 20x9.5J ET15, which tucks the tire under the fender lip on a stock-height Bentley Arnage Blue Train Series. Our Maximum Aggressive reference is 20x10.0J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Bentley Arnage Blue Train Series OE Wheel Specs
The 2005 Bentley Arnage Blue Train Series (Luxury Sedan) uses a 5x120 bolt pattern with a 72.6mm center bore. Factory wheels are F: 19x8.5J R: 19x8.5J.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Bentley Arnage Blue Train Series (2005) we drill the 5x120 pattern and cut the centre bore to 72.6mm 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.

Flush Fitment
For a flush look with minimal rubbing, F/R 20x9.5J ET15 is the recommended starting point on a stock or mildly lowered Bentley Arnage Blue Train Series.
Maximum Aggressive Fitment
F/R 20x10.0J ET15 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: F 19x8.5J ET20 → ~5.54″ F backspacing, R 19x8.5J ET20 → ~5.54″ R backspacing
- Flush: 20x9.5J ET15 → ~5.84″ backspacing
- Max: 20x10.0J ET15 → ~6.09″ 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 Bentley spec, or want a wheel built to a custom offset for your Bentley Arnage Blue Train Series? 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 Bentley Arnage Blue Train Series (2005)
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 5x120 pattern and the 72.6mm 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 — most Bentley orders on this platform land somewhere between the 20x9.5J ET15 flush setup and the 20x10.0J ET15 aggressive setup referenced above.
