INEOS Grenadier TrailGate™ Spare Tire Utility System

Lockable storage + fold-down camp table built into your spare wheel. No wasted space, no extra rack needed.

The DVA TrailGate™ Spare Tire Utility System turns your Grenadier's rear-mounted spare into a functional 3-in-1 platform: a weather-resistant lockable storage compartment, an integrated fold-down camp table, and a finished spare tire cover — all in one bolt-on unit. It fits the stock 17" and 18" spare wheel positions on all Grenadier Station Wagons, requires no drilling, and leaves your ladder and utility belt mounting positions untouched. At $799 it replaces the flimsy factory plastic cover and gives you immediate trail-side utility that owners have been asking for since the Grenadier launched.

Why the Factory Spare Tire Cover Falls Short

Every Grenadier leaves the factory with a plastic spare tire cover — lightweight, UV-treated, and perfectly functional as a cover. What it is not is useful storage. The cavity inside the spare wheel is large enough to hold a substantial amount of trail gear, but the factory cover offers no access to that space, no table surface, and no security.

This gap has generated consistent forum discussion since 2022. Owners researching upgrades often ask the same question: is there a more substantial locking option that actually uses that space?

The feedback is consistent across multiple threads: owners want better-than-plastic construction, a genuine locking mechanism, and usable access to the wheel cavity. The DVA TrailGate™ Spare Tire Utility System was designed specifically to answer all three.

DVA TrailGate™: What You Get

The TrailGate™ Spare Tire Utility System ships as a complete kit. There's nothing to source separately.

The Three Functions

1. Lockable Storage Compartment

The compartment sits inside the wheel cavity and is accessed through the cover panel. It's sized for gear that owners commonly need at the trailhead or roadside — recovery straps, soft shackles, screw pin bow shackles, first aid kit, compact tool roll, tire repair kit. The locking mechanism deters casual opportunism, and the cover panel hides the box's existence entirely.

Forum owner anand, who has run the stock Grenadier locking storage box, summed up how Grenadier owners actually use this type of storage:

The TrailGate™ compartment is designed exactly for this use case — low-value but high-utility trail gear that you want accessible immediately when you need it, without opening the rear doors or digging through the cargo area.

2. Fold-Down Camp Table

The integrated table deploys from the front face of the unit. It creates a flat work surface at a convenient standing height — useful for trail meal prep, gear sorting, map work, or roadside repairs. When you're done it folds back flush with the cover. No separate bracket, no bungee cord, no loose piece to lose on the trail.

This is where the TrailGate™ meaningfully separates itself from a standalone locking storage box. The table turns the spare tire into an active piece of your camp setup, not just a passive storage location.

3. Finished Spare Tire Cover

The system replaces the factory cover entirely and presents a clean, finished exterior. A white DVA decal provides the finishing touch. No visible hardware, no improvised mounting.

Fitment: Which Size to Order

The TrailGate™ is available in two configurations to match the two factory Grenadier wheel sizes. Order based on your wheel diameter, not tire diameter.

Overall tire diameter range: 31.5" to 33.0" OD. This covers the factory 255/70R18 and common Grenadier tire upgrades in both 17" and 18" diameter.

Installation Overview

The TrailGate™ mounts to the same three bolt locations used by the factory spare tire cover. No drilling into the Grenadier is required.

1. Remove the factory spare tire cover Remove the three Torx bolts securing the stock cover to the spare tire carrier plate. Set aside. Some owners note these bolts can seize after extended use — have a quality T30 Torx bit available and a breaker bar if needed.
2. Clear the wheel cavity With the cover off, inspect the inside of the spare wheel for balancing weights. Confirm the cavity is clear of obstructions.
3. Align the TrailGate™ Position the unit against the spare tire carrier plate, aligning the three mounting holes with the factory bolt locations.
4. Secure with provided hardware Thread in the mounting bolts and tighten to specification. The unit should sit flush against the carrier plate with no movement.
5. Load and lock Open the storage compartment, load your trail gear, lock, and close the cover panel. Deploy the camp table to confirm smooth operation before heading out.

What to Store: Practical Use Cases

The wheel cavity on the Grenadier is surprisingly spacious. With the TrailGate™ installed, the lockable compartment handles gear that doesn't belong inside the vehicle — things that get muddy, wet, or smelly on the trail.

Recovery Gear Subset

Keep a compact recovery kit permanently in the spare: one soft shackle, one screw pin bow shackle, a pair of nitrile gloves, and a short snatch strap. This is your "oh damn" kit — immediately accessible without opening the rear doors or disturbing cargo.

Camp Kitchen Basics

A small cutting board, camp knife set, and folding utensils fit easily alongside the camp table deployment — so when you fold the table down, your basic prep gear is already at hand. Trail coffee setup (hand grinder, pour-over cone, filters) also fits comfortably for a minimalist setup.

First Aid + Emergency Supplies

A compact IFAK (individual first aid kit) or trauma kit, emergency reflective triangles, and a tire plug kit are logical permanent residents. They're separate from main cargo, accessible from outside the vehicle, and secured against casual access by the lock.

Frequently Removed Trail Gear

Work gloves, tire gauges, a compact flashlight, tow hooks for the trail group, and a basic multi-tool are the kinds of items forum owners consistently mention wanting accessible outside the main cabin. The TrailGate™ compartment is purpose-built for exactly this.

Building Out Your Grenadier's Exterior Storage Ecosystem

The TrailGate™ addresses the spare tire position — but it works best as part of a complete exterior storage strategy. DVA builds several integrated exterior mounting solutions for the Grenadier that work alongside the TrailGate™ without interfering with each other.

With the TrailGate™ handling spare-tire-position storage, the ladder carrier holding recovery boards, and the Exterior Utility Belt managing body-panel-mounted gear, you can build a complete exterior organization system without touching the Grenadier's interior or roof.
