21 Inch Full-Carbon Rolls-Royce Ghost “Family” Complete Wheel Set

For the Rolls-Royce Ghost (RR21), the “Family” set refers to the official Black Badge 21-inch Carbon Fiber Composite Wheels. These were introduced as a centerpiece of the Ghost Black Badge’s engineering, blending weight reduction with the brand’s legendary durability.

1. The “Carbon-Alloy” Construction

Unlike fully aftermarket carbon fiber wheels that can be brittle, these are composite wheels designed specifically for the weight of a Rolls-Royce ($5,500+\text{ lbs}$).

• The Barrel: Constructed from 22 layers of carbon fiber laid on three axes, then folded back on themselves to create a total of 44 layers for maximum lateral strength.

• The Hub: A 3D-forged aluminum center is bonded to the carbon barrel using aerospace-grade titanium fasteners.

• The Finish: A tinted lacquer is applied to the carbon weave so it remains “visible” under direct light, while the aluminum spokes are typically finished in a high-gloss black or part-polished surface.

2. Component Details & Part Numbers (RR21 Ghost)

This is a staggered set, meaning the rear wheels are an inch wider than the fronts to accommodate the Ghost’s $600\text{ PS}$ power delivery.

4. Technical Compatibility Warning

• Series I (2010–2020) vs. Series II (2021+): The newer Ghost (RR21) uses a smaller center bore ($66.6\text{ mm}$) and a different bolt pattern than the first-generation Ghost ($72.6\text{ mm}$ / $5 \times 120$). This 21-inch carbon set will not fit 2010–2020 models without custom adapters, which is not recommended for a car of this weight.

• Tires: These wheels are factory-paired with Pirelli P Zero (Seal Inside) tires—Front: $255/40\text{R21}$, Rear: $285/35\text{R21}$.

5. Maintenance of Carbon Barrels

• Curb Damage: Unlike aluminum wheels, deep “curb rash” on the carbon barrel cannot be simply sanded and repainted. Structural damage to the carbon layers requires a specialized composite repair or complete replacement.

• Cleaning: Avoid acid-based wheel cleaners. In 2026, most owners use a PH-neutral ceramic coating to protect the resin from UV yellowing and brake dust etching.
