AL 13 R50-109RD AERO-109R Forged Wheels

AL 13 R50-109RD — AERO-109R Forged Wheel

The AL 13 R50-109RD pairs AL 13's R Series spoke architecture with the AERO-109R deep barrel profile — a purpose-engineered aerodynamic rim configuration that reduces wheel-arch turbulence, adds deep-dish visual impact, and is available in the 109RD dark smoked transparent finish for a premium look. Manufactured from 6061-T6 aerospace-grade forged aluminum at the Brea, California facility, the R50-109RD is CNC-machined to a run-out standard of 0.007 inch and built to order in any combination of diameter (13"–24"), width (5J–14.5J), offset, and bolt pattern. The base AL 13 R50 is also available without the 109R barrel in 1-piece, 2-piece, and 3-piece configurations.

The AERO-109R Series

The AERO-109R programme represents AL 13's most technically demanding barrel geometry. The deep inner barrel extends significantly further than a standard rim, creating an aerodynamically optimised channel that reduces turbulent airflow in the wheel arch. At speed, this translates to a measurable reduction in aerodynamic drag, while visually the deep dish adds dimension and concavity that enhances the presence of any large-diameter fitment. All AERO-109R models are available in 1-piece monoblock, 2-piece, and 3-piece configurations — the barrel geometry is consistent across all three; only the structural assembly method differs.

109RD Finish

The 109RD designation specifies the dark smoked transparent finish applied to the AERO-109R deep barrel, adding a stealth aesthetic that complements both light and dark vehicle colours. The smoked transparent coating is applied after the final polishing stage, over the fully machined and polished barrel surface. The result is a semi-translucent dark layer that allows the underlying metal grain and machining marks to show through, giving the wheel a depth that changes appearance under different lighting conditions. The 109RD finish is fully compatible with all spoke colour options available in the AL 13 catalogue, and can be matched to OEM or custom vehicle colours on request.

Construction Options: 1-Piece, 2-Piece, and 3-Piece

Every AL 13 AERO-109R wheel is available in three construction variants. The 1-piece monoblock is forged as a single unit — the spoke face and barrel are machined from a single billet, eliminating any assembly joints and producing the stiffest possible structure. The 2-piece variant uses a separately forged face bolted to a spun or forged barrel; this allows greater diameter and offset flexibility and enables mixed finish combinations across face and barrel. The 3-piece variant adds a separate outer barrel lip, providing the maximum step-lip depth and the widest range of offset configurations. All three variants are manufactured to the same 0.007" run-out standard.

CNC Precision and Surface Quality

Each AL 13 wheel passes through multiple CNC machining operations before finishing. Spoke profiles are roughed and finished on high-speed vertical mills, with tool paths optimised for the combined geometry of the spoke face and AERO-109R barrel. The barrel interior and outer lip are lathe-turned to dimensional tolerances tighter than SAE J2530 and TÜV LH 04 requirements. After machining, every wheel is balanced dynamically and checked on a certified run-out gauge before proceeding to the finishing stage. Wheels that do not meet the 0.010" maximum run-out limit are returned to the machine room — not passed for finishing.

Finish Options

AL 13 offers an extensive finish catalogue for the R50-109RD, including Gloss Black, Matte Black, Brushed Titanium, Polished Silver, Anthracite, Bronze, Satin Gunmetal, and full custom RAL or NCS colour matching. The 109RD dark smoked barrel can be combined with any spoke finish, creating contrast or tonal harmony depending on the vehicle's exterior. Custom two-tone combinations — for example a polished face with 109RD barrel — are available at no additional configuration charge, though lead times for complex colour combinations may extend by 1–2 weeks.

Can't Find the Right Wheel?

AL 13 operates a fully bespoke custom wheel programme through its Brea, California facility. If the R50-109RD is not quite right — wrong spoke count, different barrel depth requirement, or a completely custom spoke design — AL 13 will engineer a wheel from a new forging.

Wheel Care and Maintenance

AL 13 forged wheels require standard wheel care practices to maintain their finish. Clean regularly with a pH-neutral wheel cleaner and a soft microfibre cloth — avoid abrasive pads or acidic products that can damage the clear coat or anodised layers. For the 109RD dark smoked barrel, avoid alkaline cleaners that may affect the semi-transparent coating over time. After washing, dry thoroughly and apply a dedicated wheel sealant every 3–6 months to protect against brake dust, road salt, and UV exposure. If the wheel sustains kerb damage or corrosion, AL 13's Brea facility can refinish individual wheels to factory specification — contact [email protected] for refinishing enquiries.

Frequently Asked Questions

What is the difference between the R50-109R and the R50-109RD?
The R50-109R uses the AERO-109R deep barrel with any finish from the AL 13 catalogue. The R50-109RD specifies the dark smoked transparent finish on that same barrel — the structural geometry is identical, only the barrel surface treatment differs.

Can I order the R50-109RD in a custom diameter not listed?
Yes. AL 13 manufactures to any diameter from 13" to 24", plus extended sizes on request. Any diameter, width, and offset combination can be quoted — contact [email protected] with your requirements.

How long does production take?
Lead time is confirmed at order and depends on the specific configuration and current production queue. Typical lead times range from 8 to 14 weeks. AL 13 provides pre-shipping photos before your wheels are crated, so you can inspect them before dispatch.

Is the AERO-109R barrel available in other finishes besides 109RD?
Yes. The 109RD finish (dark smoked transparent) is one option. The same AERO-109R barrel geometry is also available in Polished, Brushed, and any custom painted finish. The 109R designation (without the D) refers to the barrel profile without the dark smoked specification.
