Trailer King Tires
Trailer King is a sub-brand under TBC Brands, one of North America’s largest private tire companies. It was launched specifically to serve the trailer and RV market, and has since become a market leader in that segment. Manufactured by TBC through partnerships in modern Asian factories, Trailer King tires adhere to stringent quality standards (they are often made by companies like Sailun that specialize in trailer tires). Over the years, Trailer King has introduced successive generations of ST tires – from the original ST Radial, to the advanced Trailer King RST, and now the latest Trailer King RST+ and Ultra STR lines. Each generation improved capacity, durability, and heat resistance to keep up with modern trailer designs (which have gotten larger and heavier). TBC provides robust warranty and support for Trailer King: these tires typically come with at least a 5-year limited warranty and road hazard coverage for the first year, reflecting TBC’s confidence. The Trailer King Ultra STR (launched around 2018) is a standout product – an all-steel radial ST tire for commercial-grade performance. Trailer King’s focus and continuous innovation have cemented its status in the USA; it’s common to see new campers and utility trailers coming OE with Trailer King tires. The brand’s tagline could very well be reliability, as it strives to be the king in its category through quality and value. Top Models Trailer King RST: The workhorse ST radial tire designed for today’s travel trailers and fifth-wheels. The RST features a modern tread with center ribs for stability and shoulder grooves for heat dissipation. It’s built with nylon overlay construction for added strength at highway speeds (important for long-distance towing). The RST series is “engineered for the demanding RV owner”, offering a smooth ride and high safety margins. Available in common sizes like ST205/75R15, ST225/75R15, and ST235/80R16, it’s a go-to for camper trailers. With an M-speed rating (81 mph) and Load Range E or higher in many sizes, the RST ensures your toy hauler or RV can handle cross-country trips with confidence. Trailer King ST Radial II: An upgraded radial trailer tire that improves upon the original with enhanced tread compounds for longer life. The ST Radial II is built for heavy-duty applications, often coming in higher load ranges (like Load Range F or G for larger 5th wheels). It maintains a highway tread pattern optimized for even wear under constant towing. If you have a large equipment trailer or a big RV, the ST Radial II provides an extra margin of durability. (It’s effectively the next-gen RST+ in some marketing materials.) Trailer King Ultra STR: A premium all-steel ST tire for high-capacity trailers. The Ultra STR stands out by using a full steel belt construction (including steel in the sidewalls), which dramatically increases load capacity and reduces trailer sway. This is the tire for serious haulers – large horse trailers, big flatbeds, or luxury RVs. It has a five-rib tread design like a commercial truck tire, aiding stability and extended tread life. With Load Range G or higher (14-ply rated) and an L-speed rating (75 mph) in sizes like ST235/85R16, the Ultra STR can handle ~4,000 lbs per tire. It’s truly built for “high-load capacity trailer applications”, combining strength and endurance for long-haul reliability. Key Features & Benefits Optimized for Trailers: Unlike passenger or LT tires, Trailer King’s ST tires have stronger sidewalls to reduce flex (important to minimize trailer sway at highway speeds). They are engineered to run cooler under heavy loads, preventing blowouts during long summer drives. The tread patterns are usually shallow and rib-like, prioritizing stability and low rolling resistance over aggressive traction (trailers don’t need traction like a drive tire). This specialization means when you buy Trailer King, you get a tire 100% intended for trailer service, with no compromises. High Load Ratings: Trailer King tires cover a wide range of ply ratings – from 6-ply (Load C) for small utility trailers up to 14-ply (Load G) for large RVs. They are built to carry heavy weights with ease. Many models incorporate nylon cap plies or full steel belts for extra load support at higher speeds. For example, the RST in Load Range E can often carry ~2,830 lbs per tire, while the Ultra STR in Load Range G can carry ~4,080 lbs. This ensures safe towing of even the heaviest trailers. Durability & Long Life: The combination of robust construction and advanced compounds yields excellent tread life and resistance to failure. Trailer King tires are known for exceptional durability, often outlasting cheaper trailer tires. Their “high safety levels throughout their performance” have made them favorites among RV owners who don’t want tire problems on the road. Additionally, these tires often have UV-resistant sidewall formulations to weather years of outdoor storage without cracking. Smooth, Comfortable Towing: A key benefit, especially for RVers, is the comfortable and stable towing experience. Trailer King tires are designed to reduce trailer sway and improve tracking. That means when an 18-wheeler passes your camper on the highway, your trailer stays steady. The tires’ shock absorption and consistent footprint also help protect your trailer’s suspension and contents from excessive jarring. In short, they contribute to a safer, easier tow. Trusted by Manufacturers & Owners: Trailer King has become a “widely known brand for premium trailer tires” because it’s trusted by many trailer manufacturers as OEM and by countless owners for replacement. This real-world vote of confidence is backed by Trailer King’s warranty and TBC’s support network – giving owners assurance that if an issue arises, they are covered. The brand’s “exceptional value for the price” and broad size availability make it an unbeatable competitor in the trailer tire segment.
