SeaSense Spare Tire Carriers

SeaSense Spare Tire Carriers: Built for the Demands of Trailer Towing

When you're hauling a boat or utility trailer down the highway, a flat tire shouldn't mean being stranded roadside. SeaSense — a marine and trailer accessories brand serving the industry since 1984 — brings that same commitment to durability and practicality to its line of spare tire carriers. Designed with the unique challenges of boat trailer use in mind, SeaSense spare tire carriers are engineered to withstand the corrosive environments that come with frequent water exposure, saltwater launches, and the general wear of road towing.

Galvanized Construction for Corrosion Resistance

The hallmark of SeaSense's spare tire carrier lineup is its galvanized steel construction. Both of the brand's primary carrier styles — the Offset Spare Tire Carrier and the U-Bolt Spare Tire Carrier — feature galvanized finishes specifically chosen to resist the rust and corrosion that can plague trailer hardware over time. For boat owners who regularly back their trailers into freshwater lakes, rivers, or saltwater bays, this kind of protection is essential to long-term reliability.

Two Practical Mounting Styles

SeaSense addresses the two most common mounting needs in trailer towing with a pair of purpose-built designs:

• Offset Spare Tire Carrier: This model positions the spare tire 4¾" up and 4½" out from the trailer's frame, keeping the wheel clear of the tongue and hitch hardware. It fits all trailer tongues up to 3" wide by 4" tall, and adjusts to accommodate both four- and five-hole wheels. Hardware is included for a complete, out-of-the-box installation.
• U-Bolt Spare Tire Carrier: A simple, compact solution that mounts the spare securely via a galvanized U-bolt. It fits tires sized 8" to 14" with four- or five-hole bolt patterns, and includes two nuts for easy fastening. Its straightforward design makes it an ideal choice for trailers where simplicity and minimal profile matter most.

Versatile Fitment for a Wide Range of Trailers

Although SeaSense is rooted in the marine world, their spare tire carriers are not limited to boat trailers alone. The adjustable wheel compatibility and universal tongue fitment make these carriers well-suited for utility trailers, camper trailers, and other light-duty towing applications. The included hardware means there's no need for a separate trip to the hardware store — everything needed for mounting is in the box.

A Brand Committed to Trailer Accessory Quality

SeaSense has spent decades refining its trailer accessories lineup, which spans everything from trailer jacks and winch straps to lighting and hub kits. Their spare tire carriers reflect the same philosophy: practical engineering, durable materials, and ease of installation. Backed by the brand's long history of serving more than 2,000 wholesale customers, these carriers represent a reliable choice for anyone who wants peace of mind on the road.
