3D Design Type 4 2-Piece Forged Wheels

3D Design Type 4 — 2-Piece Forged Wheels for BMW X5 and X6

The 3D Design Type 4 (T4F — Type 4 Forged) is a 22-inch 2-piece forged aluminum wheel engineered by 3D Design Corporation Japan for BMW's high-performance SAV lineup. Combining a precision-forged aluminum face with a flow-formed rim barrel, the Type 4 satisfies the demanding JWL 815 kg load certification — the mandatory standard for heavy SUVs and seven-seat configurations in the Japanese and European markets. Manufactured entirely in Japan to 3D Design's exacting tolerances, the Type 4 delivers the brand's hallmark precision craftsmanship to the BMW X5 M and X6 M segment, providing a wheel solution that combines high load capacity with the aesthetic refinement expected of forged billet construction.

Available Sizes

The Type 4 Forged is produced under 3D Design's custom forged program, covering 18" through 24" by order. Standard catalogue configurations for the SAV application are as follows:

• Diameters available: 18" | 19" | 20" | 21" | 22" | 23" | 24"
• Standard finish: Gunmetal × Standard Rim (GM×STD) — brushed gunmetal face, diamond-cut standard rim barrel
• Bolt Pattern: 5×120 mm (BMW SAV standard)

The 5 mm offset adapters supplied with ET34 and ET27 configurations allow a single set of wheels to cover the full F15/F16/F85/F86 model range without additional hardware investment.

Need a Different Size?

As a custom-order forged wheel, the Type 4 is manufactured to individual specification. Offsets can be adjusted in 1 mm increments, widths in 0.5J steps, and diameters from 18" to 24". If your BMW SAV application requires a configuration not listed above — including non-standard backspacing for track-width adjustments or flush fitment builds — contact our fitment team at [email protected] for a bespoke quotation.

Vehicle Fitment Guide

The Type 4 Forged was engineered specifically for BMW's high-torque, high-mass SAV platforms. Confirmed fitment specifications:

• BMW F16 X6 (all variants) — F:10.0J×22 ET+39 / R:11.5J×22 ET+27; standard configuration
• BMW F86 X6 M — F:10.0J×22 ET+34 / R:11.5J×22 ET+27; 5 mm adapter at front (ET34 variant)
• BMW F15 X5 (all variants) — compatible via ET+39 configuration; consult fitment team for body-width specifics
• BMW F85 X5 M — compatible via ET+34 configuration; same fitment logic as F86 X6M
• Heavy SUV and 7-seat configurations — JWL 815 kg load certification covers vehicle gross weights up to 3,260 kg on standard 5-lug BMW pattern

The staggered fitment (10.0J front, 11.5J rear) is specifically engineered to match the BMW SAV's factory front-to-rear width offset, filling the wider rear arch while maintaining correct front steering geometry. No spacers or modifications to wheel arches are required on standard F15/F16/F85/F86 bodies.

Other Bolt Patterns Available

The standard Type 4 Forged configuration targets PCD 5×120 mm (the BMW SAV bolt circle). Through 3D Design's custom program, non-standard PCDs can be accommodated — including 5×112 (Mercedes-Benz), 5×130 (Porsche), and 6×139.7 (Toyota Land Cruiser) for owners retrofitting the Type 4 design language to non-BMW SAV platforms.

2-Piece Forged Construction: Engineering Advantage

Unlike a monoblock 1-piece wheel — where the face and barrel are forged as a single billet — the T4F's 2-piece architecture separates the structural elements. The face is precision-forged from high-strength 6061-T6 aluminium, then CNC-machined to final shape and finish. The rim barrel is independently flow-formed to achieve precise wall thickness and diameter, then assembled to the face with a ring of stainless-steel hardware. This approach delivers three key advantages over cast or flow-formed alternatives:

• Custom offset flexibility: Rim depth can be adjusted at assembly to tune the offset precisely — impossible with monoblock forgings of fixed profile.
• Separate repairability: In the event of rim damage, the barrel can be replaced without scrapping the forged face — a significant cost advantage for a premium SAV wheel.
• High load rating with reduced weight: By optimising each component independently, the T4F achieves JWL 815 kg certification at a lower mass than an equivalently rated cast wheel.

Frequently Asked Questions

What is the 3D Design Type 4 Forged?
The Type 4 Forged (T4F) is a Japanese-made 2-piece forged aluminium wheel designed specifically for the BMW X5 (F15), X6 (F16), X5 M (F85), and X6 M (F86) SAV platforms, certified to the JWL 815 kg heavy-load standard.

What is the difference between the Type 3 and Type 4?
The Type 3 (T3F) is a lightweight 1-piece monoblock wheel in 19" and 20" diameters, optimised for BMW sports sedans and M cars. The Type 4 (T4F) is a 2-piece forged wheel in 22" diameter with an 815 kg load certification, purpose-built for heavy BMW SUVs. The two models share 3D Design's Japanese manufacturing heritage and custom offset program, but serve fundamentally different vehicle categories.

Can the Type 4 be ordered in custom offsets and widths?
Yes. 3D Design's custom program allows offset adjustments in 1 mm increments within the permissible range for each width. Width options from 8.5J to 12.5J in 0.5J steps are possible depending on the diameter. Contact us to configure your exact specification.

What load rating does the Type 4 carry, and why does it matter?
The Type 4 Forged meets the JWL 815 kg standard — required for vehicles classified as heavy SUVs and those with 7-seat configurations. A standard JWL-certified wheel (550–600 kg range) may not be approved for use on vehicles like the X5 M or X6 M with performance tyres at track events or in markets where aftermarket wheel certification is enforced. The 815 kg rating eliminates this concern.

Does the Type 4 fit the newer G05 X5 or G06 X6?
The original catalogue targets F15/F16/F85/F86 (2013–2019 generation). Through the custom forged program, T4F-style configurations can be produced for G05/G06 with updated offset specifications. Contact us for a G-series fitment consultation — engineering validation is required per chassis.

Does the Type 4 require special bolts?
Wheel bolts are not included. Standard M14×1.25 bolts suit most ET+39 configurations. The ET+34 variants may require extended bolts (available from BMW dealers or 3D Design at approximately ¥700/ea excluding VAT). We advise specifying the bolt length when ordering.

What tyre sizes are recommended for the Type 4?
For the F16 X6 staggered setup (10.0J×22 front, 11.5J×22 rear): 265/35 R22 front, 295/30 R22 rear is a common high-performance fitment. For the F86 X6M, 265/35 R22 front / 295/30 R22 rear maintains the stock tyre width ratio. Always verify rolling radius match between front and rear to avoid DSC calibration issues.

Type 4 Forged — Wheel Care

The T4F's Gunmetal × Standard Rim finish combines a brushed-and-anodised aluminium face with a diamond-cut standard rim barrel. Each surface requires specific maintenance to retain its appearance long-term.

• Brake dust removal: Rinse with water after each drive in wet or dirty conditions. Brake dust is corrosive to anodised aluminium if left for extended periods.
• Cleaning agents: Use a pH-neutral wheel cleaner only. Avoid acidic (etching-type) or strongly alkaline (industrial degreaser) products — both attack the anodised layer.
• Diamond-cut rim care: The diamond-cut rim surface is sealed at manufacture. Apply a dedicated ceramic or wax sealant every 3–6 months to protect the cut aluminium from oxidation.
• Physical damage: Avoid automatic car washes with rotating brushes — these scratch the brushed face. Clean by hand with a soft microfibre mitt and dedicated wheel mitt.
• 2-piece hardware: Inspect the ring of assembly bolts between face and rim annually. Retorque to 3D Design specification (typically 8–10 Nm) if any movement is detected. Clean the bolt area with a soft brush during each wash.
• Tyre mounting: When mounting or dismounting tyres, ensure the tyre machine operator is aware of the 2-piece construction. The rim flange must not be struck or forced — use a drop-centre machine and bead lubricant appropriate for alloy wheels.
