About Towmax Tires

When it comes to keeping a towed trailer rolling safely down the highway, the tire beneath it carries enormous responsibility. Towmax is a brand built entirely around that singular mission: engineering premium trailer tires that deliver long-lasting, dependable performance across the full range of towed applications. Whether the rig behind you is a travel trailer, a boat trailer, a utility hauler, or a fifth wheel, Towmax has developed a tire engineered specifically for the task.

Towmax operates as part of TBC Brands, a major force in the tire industry responsible for a wide portfolio of consumer and commercial tire lines. That backing gives Towmax access to significant engineering and distribution resources while keeping its product focus laser-sharp on the specialty trailer tire segment.

The Towmax Product Lineup

The brand's two flagship lines — the Towmax STR II and the Towmax Vanguard — represent distinct tiers of trailer tire performance, both built on radial construction principles designed for the unique stresses of towed-trailer use.

The Towmax STR II is purpose-built for travel trailers, fifth wheels, boat trailers, and similar towed applications. It features an optimized five-rib tread design engineered for maximum ride stability, a specialized tread compound aimed at reducing rolling resistance, and a computer-designed tire profile to help manage heat buildup — one of the most common causes of trailer tire failure on long highway runs. Select sizes also incorporate nylon overlays for added strength and durability.

The Towmax Vanguard represents the next evolution in the Towmax family, designed to set a new benchmark for quality and performance in the ST (Special Trailer) tire category. The Vanguard features decoupling grooves and an optimized tread depth to reduce rolling resistance and limit heat buildup over long hauls. Wide shoulders and an extra-wide tread face provide even load distribution and a larger contact patch for improved stability. Nylon overlays on all sizes help achieve an 87 mph maximum speed rating, while scuff protectors along the sidewall help maintain the tire's appearance and guard against curb and road damage.

Why Trailer Tires Are a Specialized Category

ST-rated trailer tires like those in the Towmax lineup are not interchangeable with passenger or light-truck tires. They are engineered with stiffer sidewalls to handle the unique lateral forces generated during towing, and their tread compounds are formulated to handle sustained highway loads at consistent speeds. Choosing the right load range and ply rating for the weight of your trailer is critical — and Towmax offers a range of sizes and load ratings to match everything from a lightweight utility trailer to a fully loaded fifth wheel.

Warranty and Consumer Protection

The Towmax Vanguard comes backed by a Consumer Warranty Protection Plan that includes a five-year nationwide limited warranty for workmanship and materials, a two-year nationwide roadside assistance program, and a one-year road hazard protection plan — giving trailer owners added peace of mind on every journey.
