The rear-mounted spare tire is one of the most overlooked storage opportunities on an off-road or overland build.

The challenge is that most storage solutions either take up valuable roof rack space, eat into interior cargo room, or require complicated fabrication that doesn’t make sense for a trail-ready setup.

We wanted a better use of that space.

The American Adventure Lab M.A.S.S. Spare Tire Platform (STP) turns your spare tire into a rigid, modular cargo platform, giving you a strong exterior mounting surface for recovery gear, storage, and trail essentials without sacrificing roof or interior space.

Features & Benefits:

• Fits most vehicles running 33"–40" spare tires (carrier dependent)

• Lightweight 5052 aluminum construction

• Weighs approximately 18 lbs

• Supports up to 100 lbs of evenly distributed load (dependent on carrier strength and setup)

• No drilling or permanent vehicle modifications required

• Secure strap-based mounting system for easy installation and removal

• Designed with the M.A.S.S. modular grid system for accessory integration

• Compatible with a wide range of Jeep, Bronco, Toyota, and overland platforms

• Works best with swing-out tire carriers for maximum stability

• Creates usable rear-mounted storage space without interfering with roof rack systems

• Designed and manufactured in St. George, Utah, USA

Installation Notes:

• Simple strap-based installation around the spare tire

• No cutting, drilling, or fabrication required

• Easily removable if your setup changes

• Best performance when paired with a sturdy swing-out tire carrier

• May require adjustments depending on tire size and carrier geometry

Frequently Asked Questions

Will this fit my vehicle?

The STP is designed to work with most 33"–40" spare tires found on popular platforms including Jeep Wrangler, Ford Bronco, Toyota 4Runner, and similar overland vehicles.

How much weight can it hold?

Up to 100 lbs of evenly distributed gear, though actual capacity depends on your spare tire carrier and mounting configuration.

Do I need to drill into my vehicle?

No. The system uses a fully strap-based design with no permanent modifications required.

Why use the spare tire instead of a roof rack?

It keeps weight low, frees up roof rack space for tents and larger gear, and improves accessibility since you’re not climbing to retrieve equipment.

Will it interfere with my tailgate?

In most setups, no—but clearance depends on tire size, wheel offset, and carrier design.

If you’re looking to turn unused space into functional storage without overcomplicating your build, the M.A.S.S. Spare Tire Platform is a straightforward, modular solution.

We're happy to answer any questions about fitment, compatibility, or installation.

Really appreciate that—this is exactly what we were going for. The goal was to turn otherwise unused space into something functional without complicating the build, so it’s great to see it landing that way. Thanks for the feedback.

Where do YOU think the spare tire on a Ranger is?

How is this for the RR/Ranger?

The details are above, I particularly LOVE to see these options and really appreciate seeing them shared. Applications are sometimes more universal but AAL products are so great to see, I'm certain they have future RR/Ranger specific parts in the pipeline for us!

Just to clarify, this is really intended for aftermarket tire carriers, not the stock Ranger spare setup. Everyone builds their rigs differently, but the goal here is a solid mounting solution for those running aftermarket carriers where accessory mounting is more flexible.

Oh so you mean like if the spare is in the bed? Maybe clarify that otherwise you're gonna get these comments.

It isn't really a new idea.
I had a rack on my spare carrier in my TJ 20 years ago, a jerry can on each side and a platform on top.

This would be ideally a rear bumper with a tire mount or swing-out bumper setup!

Does anyone make a swing out carrier for the RR/Ranger?

I Believe the most popular option available is the RIGd Ultraswing Spare Tire Hitch!
