About Trailer King Tires

When it comes to towing confidence, few names carry as much weight as Trailer King Tires. A proud brand under the TBC Brands family, Trailer King has been a cornerstone of the North American replacement tire market for more than fifty years. Built around four guiding principles — Performance, Engineering, Quality, and Value — the brand has earned a loyal following among RV enthusiasts, commercial haulers, and weekend adventurers alike.

Purpose-Built for Trailers

Unlike general-purpose passenger or light truck tires, Trailer King products are engineered specifically for the unique demands of towing. Special Trailer (ST) designation means these tires are designed with stiffer sidewalls, higher load-carrying capacity, and enhanced heat resistance compared to standard tires — critical attributes when a vehicle is handling the lateral forces and sustained highway speeds that trailer towing demands. Whether you're pulling a boat, a horse trailer, a utility flatbed, or a full-size RV, running the right tire makes all the difference.

Trailer King's trailer tire lineup spans a wide range of sizes and constructions to match virtually any towing application. Key product lines include:

• Trailer King RST — An ST radial built for modern trailer applications, featuring segmented-mold construction for exceptional uniformity and an optimized tread depth that reduces rolling resistance and heat buildup. Most sizes include nylon overlay construction for added strength under heavier loads.
• Trailer King Ultra STR — An all-steel highway rib tire designed for high-load capacity applications, featuring a five-rib, four-groove pattern, 12/32nds of tread depth, stone ejectors, and cross-rib sipes for reliable wet and dry traction.
• Trailer King II — A next-generation ST radial engineered with an improved tread design and compound to resist heat buildup and deliver longer, more even tread wear.

Quality You Can Count On

Trailer King backs its tires with a nationwide warranty against defects in workmanship and materials — covering either the life of the original tread or five years from the date of purchase, whichever comes first. That kind of commitment is a strong indicator of the confidence the brand places in its own manufacturing standards. Customers consistently rate Trailer King tires highly for durability, load performance, and tread longevity — qualities that matter most when you're miles from the nearest service center with a loaded trailer in tow.

Where Value Meets the Road

Part of what sets Trailer King apart is its dedication to delivering premium trailer-specific engineering without demanding a premium price. The brand's wide selection of ST Radial sizes means dealers and consumers can find the right fitment for a broad spectrum of trailers without compromising on performance. Whether you're a first-time camper outfitting a small utility trailer or a commercial operator managing a fleet, Trailer King offers a practical, dependable solution backed by decades of tire industry expertise.
