Spare wheel cover Mansory Carbon for Mercedes G-class G500 / AMG G63 W463A

Spare Wheel Cover Mansory Carbon for Mercedes G-class G500 / AMG G63 W463A

The swing-out tailgate carrying an external spare wheel is among the most recognisable signatures of the G-class across all four generations — a functional carry-over from the platform's military origins that persisted onto the W463A. Mercedes retained this arrangement and equipped the gate with a body-coloured painted steel disc cover: functional, but offering no visual distinction in a vehicle marketed at the top of the performance SUV segment. Mansory converts that steel disc into a hand-laid carbon fibre face cover, bringing the same material language that defines the Mansory Carbon Body Kit for Mercedes G-class W463A G500/G63 to the most prominent rearward-facing surface of the vehicle. This listing covers the plain spare wheel cover — a flush-face disc with a single centred Mansory motif. Two companion pieces are catalogued separately: the spare-wheel-cover-ii with a spoke-pattern pressed geometry and the spare-wheel-cover-frame, which is a structural mounting surround for the wheel carrier rather than a disc face cover.

Construction & Materials

The cover is hand-laid from 3K twill carbon pre-impregnated fabric. Technicians apply alternating 0°/90° and ±45° plies against a precision CNC-machined aluminium tool that reproduces the curvature and hub-lock ring recess geometry of the OEM wheel mounting interface exactly. The consolidated laminate undergoes autoclave cure at 120 °C and 6 bar for 90 minutes. The autoclave process is essential to the ±0.5 mm flatness specification: only the controlled thermal expansion of an aluminium tool at elevated pressure can prevent the warp that vacuum-bag atmospheric curing introduces to a large-diameter thin disc. Post-cure operations include CNC router trimming of the disc perimeter, five-stage abrasive finishing, and application of UV-stabilised two-part polyurethane lacquer in gloss or satin.

The hub-lock ring recess is machined post-cure to seat the locking ring flush without introducing lateral runout to the spare wheel. Stainless steel threaded inserts are pressed into the recess walls to carry mount loads; this prevents thread-stripping in the epoxy matrix under repeated removal and reinstallation cycles.

Design & Visual Function

The plain cover's design logic is deliberate restraint. Rather than competing with the spoke pattern of the companion Cover II or the structural lattice of the Cover Frame, this version presents the carbon weave as a single uninterrupted disc — the material itself is the statement. The centred Mansory motif occupies a modest hub-area footprint, functioning as identification rather than focal point. When the tailgate swings to the loading position and the cover faces rearward, the full 3K twill disc catches directional light in a way animated metallic flake paint cannot approach, even at a distance where the weave pattern is not individually resolved.

The cover sits flush with the hub-lock ring perimeter, presenting no protruding edge that could catch on garage door frames or loading-bay equipment. The thickness delta between the carbon disc and the OEM steel disc is under 0.5 mm at the outer rim, so the swing arc of the tailgate is unchanged. At 1.45 kg versus approximately 3.2 kg for the steel cover, the mass reduction also marginally reduces inertial load on the tailgate hinge — a tangible benefit if the hinge check-strap is approaching its service interval.

The UV-stabilised lacquer sustains weave colour and depth over extended ownership. Untreated carbon laminate exposed to direct sunlight will yellow and dull within two to three years; the two-part polyurethane clear coat on this cover is formulated with benzotriazole UV absorbers for automotive exterior use, providing a meaningfully longer gloss-retention window before refinishing is required.

Compatibility & Fitment

The cover is matched to the W463A fourth-generation Mercedes G-class from 2018 onward. Compatible engine variants: G500 with M256 inline-six turbocharged engine, G550, G400d, G350d diesel trims, and AMG G63 with M177 twin-turbocharged 4.0-litre V8. The pre-2018 W463 used a different hub-lock ring diameter and a flatter disc geometry — this cover does not fit those earlier vehicles. The cover mounts to the spare wheel via the hub-lock ring, not to the tailgate hinge bracket, so the spare wheel must be removed from the gate to access the cover's mounting interface. LHD and RHD variants share the same tailgate assembly; the cover fits both equally without modification. The maximum tyre outer diameter accommodated is 780 mm, corresponding to 275/50 R20.

Installation & Reversibility

Remove the spare wheel from the tailgate hinge carrier using a 19 mm socket to release the locking lug. With the wheel on a flat surface, remove the OEM steel cover by releasing the hub-lock ring using the standard vehicle jack-kit tool. Seat the Mansory carbon cover over the hub with the centred motif oriented vertically — an orientation mark on the reverse of the cover provides reference. Thread the hub-lock ring onto the stainless inserts and torque to 25 Nm; do not exceed this value, as over-torquing risks stripping the insert threads in the epoxy matrix. Reinstall the wheel on the tailgate carrier. Total elapsed time for a single technician is approximately 25 minutes including wheel removal and reinstallation. The process is fully reversible and the OEM steel cover can be reinstalled at any time without any modification to the wheel or gate.

Pairing within the Mansory G-class W463A G500/G63 programme

The plain spare wheel cover anchors a three-part spare-wheel system. The Mansory spare wheel cover II offers an alternative visual treatment with a spoke-pattern geometry pressed into the disc — the two face covers represent different aesthetic choices rather than a stacking arrangement. The Mansory spare wheel cover frame attaches to the tailgate around the wheel carrier and can be combined with either face cover to give the full spare-wheel assembly a bordered carbon presentation. The Mansory carbon rear door panel addresses the inner face of the swing gate, so the tailgate presents carbon detail on both faces when the door is opened.

Maintenance & Durability

The spare wheel cover occupies an unusually exposed position: rearward-facing at bumper height where road spray, stone chips, and particulate from following traffic impact directly. A ceramic coating applied over the factory lacquer provides an additional sacrificial barrier. Inspect the lacquer edge trim monthly for stone-chip damage; any chip exposing raw carbon should be touched up with compatible clear lacquer before moisture enters the laminate edge. Avoid pressure-washing the cover at less than 30 cm distance or at steep angles — pressurised water can force ingress under lacquer at existing chips and accelerate delamination around the perimeter.

Solvent-based fallout removers and iron-decontamination sprays should not be used on lacquered carbon surfaces. Monthly application of a PTFE or SiO₂ spray sealant after washing is sufficient to maintain the hydrophobic barrier. Annual machine-polishing followed by ceramic sealant application is the recommended maintenance standard to sustain gloss quality across multiple years of ownership.

Lead Time & Warranty

Lead time is 2–6 weeks from order confirmation, reflecting the autoclave scheduling and post-cure hub-recess machining at Mansory's facility. Hodoor provides a 12-month warranty against manufacturing defects including laminate delamination, hub-recess thread failure, and lacquer adhesion defects present at delivery. Damage from over-torquing, chemical attack, road debris impact, or improper removal is not covered under warranty.

FAQ

Q: What is the difference between this cover, spare-wheel-cover-II, and the cover-frame?
A: This plain cover is a flush-face carbon disc with an unbroken twill surface and a centred Mansory motif. Cover II features a spoke-pattern geometry pressed into the disc face for a more open aesthetic. The Cover Frame is a structural perimeter surround that mounts to the tailgate around the wheel carrier rather than covering the wheel face — it can be combined with either face cover to frame the entire spare-wheel assembly in carbon.

Q: What maximum wheel diameter does the cover accommodate?
A: The cover accepts spare wheels with an overall tyre outer diameter up to 780 mm, corresponding to a 275/50 R20 tyre. Wider or taller sections may contact the outer rim of the disc and should be confirmed with the Hodoor team before ordering.

Q: Does the cover stay on the tailgate when the wheel is removed?
A: No. The cover mounts to the spare wheel via the hub-lock ring, not to the tailgate bracket. When the spare is removed for use, the cover comes with it and cannot remain mounted to the gate independently.

Q: Is the cover compatible with W463A models specified without an external spare wheel?
A: No. Some W463A vehicles are delivered without the external spare carrier by regional or customer specification. The Mansory cover requires the spare wheel hub interface for mounting and has no applicable attachment point on those variants.

Q: Can the cover be ordered in matte finish instead of gloss lacquer?
A: Yes — satin finish is available at the ordering stage and is specified at time of enquiry. Full matte is available as a custom option with extended lead time. Gloss is the standard production variant.
