The Stromberg Carlson TR-2 Folding Spare Tire Carrier is a straightforward solution for RV and trailer owners who need to mount a spare tire on a square bumper. Designed to fit 4-inch square bumpers and accommodate 15- and 16-inch wheels, this carrier aims to solve the common problem of where to store a spare without taking up valuable interior or rooftop space. In practice, it functions as a bracket that attaches directly to the rear bumper, allowing the tire to fold down for access to the back of the vehicle—a useful feature when you need to open a trunk or rear hatch.
One of the key functional features is its folding mechanism. The carrier hinges down, which means you can lower the tire without unbolting it entirely. This is handy for accessing storage compartments or the back of a trailer that might otherwise be blocked by a fixed mount. The construction is welded steel with a black powder-coated finish, which seems durable enough for typical highway use and exposure to weather. Installation involves bolting the carrier onto the bumper, and it comes with hardware that fits standard 4-inch square tubes. The design is fairly simple, and most owners with basic tools should be able to mount it in under an hour.
However, there are some trade-offs to consider. The carrier is rated for a maximum tire weight, and while it handles standard RV tires without issue, heavier setups—like larger off-road tires or dual-wheel configurations—may push its limits. The folding mechanism, while convenient, can develop some play over time if not periodically tightened. Additionally, the carrier positions the tire relatively close to the bumper, which might interfere with rear clearance on uneven terrain. If you frequently back into tight spots or drive on rough roads, the tire could scrape or snag on obstacles.
Compared to a generic fixed spare tire mount, the TR-2 offers the advantage of foldability, which is a clear benefit for those who need occasional rear access. But if you rarely need to open the back, a simpler, non-folding bracket might be more stable and less expensive. There are also alternatives like hitch-mounted carriers, which attach to a receiver and can be more versatile for different vehicle types, but they often require a hitch and may not fit square bumpers at all. The Stromberg Carlson is specifically tailored for bumpers, so it fills a niche that hitch mounts don’t cover.
Who is this carrier suitable for? It works well for RV owners with a 4-inch square bumper who carry a single spare tire and need occasional access to a rear door or storage compartment. It’s also a decent option for utility trailers or campers where the spare would otherwise be strapped down loosely. On the other hand, it may not be ideal for those with heavier tires, such as large truck spares, or for owners who want a permanent, wobble-free mount for rough off-road conditions. The carrier is also less practical if your bumper is not square or if you prefer a more integrated look.
In terms of real-world usage, the TR-2 does what it claims: it holds a spare tire securely on a square bumper and folds down when needed. The finish holds up reasonably well against rust, though chipping can occur if the carrier is hit by debris. The hardware is adequate but not premium, so replacing bolts with stainless steel ones after a year or two might be wise for longevity. Overall, it’s a functional product that addresses a specific need without unnecessary frills. If you have the right bumper and tire size, it’s a practical choice—just don’t expect it to handle extreme loads or provide rock-solid rigidity in all conditions.
For most RV and trailer owners, this carrier is a solid middle-ground option. It’s not the most heavy-duty or the cheapest, but it balances convenience and durability reasonably well. If you’re looking for a simple way to mount a spare on a square bumper and value the folding feature, the Stromberg Carlson TR-2 is worth considering. Just be realistic about its limitations and ensure it fits your specific tire and bumper setup before purchasing.
