Stromberg Carlson TR-2 Folding Spare Tire Carrier for RV Bumpers

In this review the Stromberg Carlson TR-2 folding spare tire carrier is recommended for RV and trailer owners who need a sturdy, space-saving mount for a spare 15' or 16' wheel. The TR-2 stands out because it folds to allow rear access while still providing robust support, and the review emphasizes that the construction and included hardware make it a practical upgrade for travel trailers with 4' square bumpers. For anyone who wants a reliable, long-lasting spare mount without complicated installation, the TR-2 delivers.

Key Features

• Universal compatibility: Fits most trailers with 4' square bumpers and accepts 15' and 16' travel trailer tires so it can be used on a wide range of RVs and trailers.
• Folding design: The TR-2 folds down to allow access to rear compartments, which keeps the spare accessible without blocking bumper-mounted storage or doors.
• Heavy-duty construction: Made from extra-thick welded steel with a black powder-coated finish to resist road wear and provide durable, long-term support for the spare tire.
• Secure mounting: A double-nut design reduces the chance of loosening during travel, helping to keep the spare tire firmly in place on rough roads.
• Hardware included: Ships with the necessary mounting hardware and clear instructions so installation on a 4' square bumper can be completed quickly.

Who It's For

The TR-2 is aimed at RV and trailer owners who need a reliable external spare carrier that does not permanently obstruct rear access. It is especially suited to travel trailers and campers that use 15' or 16' tires and have a 4' square bumper; owners who value build quality and a neat black finish will appreciate it.

Those who have smaller bumpers, nonstandard mounting systems, or require a low-profile undercarriage spare should look elsewhere. Also, buyers expecting a carrier for larger truck tires beyond 16' should consider heavier-duty, purpose-built mounts.

Pros & Cons

Pros

• Sturdy, extra-thick welded steel construction provides confidence in long-term durability.
• Folding TR-2 design allows rear bumper and compartment access without removing the tire.
• Includes mounting hardware and clear instructions, making installation straightforward for most users.

Cons

• Designed specifically for 4' square bumpers and 15' to 16' tires, so it is not universal for all vehicles.
