MIDDLETOWN, Del., Aug. 24, 2026 /PRNewswire/ — The global Trailer Tires (ST-Type) Market was valued at USD 8.32 billion in 2025 and is projected to expand from USD 8.8 billion in 2026 to USD 13.69 billion by 2035, registering a compound annual growth rate of 5.03% during the forecast period, according to the latest market intelligence study published by Radial Insights.

The new study, titled “Trailer Tires (ST-Type) Market Size, Share, Growth & Trends Analysis, 2025–2035,” examines how rising recreational vehicle ownership, trailerable boat demand, radial ST tire adoption, aging trailer fleets and rapidly expanding e-commerce channels are reshaping the global specialty trailer tire industry.

The report provides detailed intelligence by trailer type, construction, end user, brand tier, distribution channel and region. It also evaluates replacement cycles, load-range requirements, radialization, OEM fitment trends, online aftermarket growth, pricing dynamics and competitive positioning across recreational, commercial, agricultural and marine trailer applications.

U.S. RV and Boat Trailer Base Creates Sustained ST Tire Demand

• North America remains the core demand center for ST-type trailer tires because of its large installed population of travel trailers, fifth wheels, utility trailers and trailerable boats.
• RV Industry Association data show that U.S. wholesale RV shipments reached a record 600,240 units in 2021. Although shipments normalized from that peak, 2025 still finished with 342,220 units, including 306,191 towable RVs. The association’s 2025 owner profile estimates that approximately 8.1 million U.S. households own an RV.
• Marine recreation adds another substantial replacement pool. New U.S. boat retail sales reached 215,237 units in 2025, with more than 90% represented by personal watercraft, aluminum fishing boats and other smaller, trailerable vessels.
• Every new towable RV or boat trailer introduces multiple ST-type tires into the installed base. These tires subsequently enter recurring replacement cycles driven by mileage, load stress, heat exposure, aging and prolonged periods of storage.
• Demand is especially strong across 14-inch to 16-inch sizes widely used on travel trailers, utility trailers and marine trailers.

Key Insights From Radial Insights’ Market Study

• Utility/cargo trailers and travel trailers represent major demand categories because they serve both commercial hauling and recreational towing applications.
• Radial construction is gaining share as users prioritize cooler operation, improved highway stability, longer tread life and stronger sustained-speed performance.
• Replacement and aftermarket demand leads the market because aging trailers and recurring tire wear create repeat purchasing opportunities beyond initial OEM fitment.
• Online channels are the fastest-growing distribution route as consumers increasingly compare ST sizes, load ranges, speed ratings, warranties and prices digitally before purchasing.
• Tier 1 manufacturers benefit from demand for stronger construction, higher load ratings, improved heat management and warranty-backed products for long-distance towing.

“Trailer tires are increasingly being purchased on performance criteria rather than price alone. RV and boat owners are paying closer attention to load range, heat buildup, speed ratings and durability, particularly for highway towing. This is accelerating radial adoption and creating a more valuable replacement market for manufacturers, dealers and digital tire retailers,” said Michael Thompson, lead specialty and recreational tire analyst at Radial Insights.

Radial ST Tires Reshape the Product Mix

The migration from bias ply to radial construction is one of the most important technology trends in the Trailer Tires (ST-Type) Market.

Radial tires provide a larger contact footprint, improved heat dissipation and more even tread wear, characteristics that are particularly valuable for highway-oriented trailers operating at sustained speeds.

Bias ply construction continues to serve shorter-distance, rough-terrain and cost-sensitive applications, but radial tires are gaining preference among RV manufacturers, premium trailer brands and aftermarket consumers.

E-Commerce Changes Trailer Tire Replacement Buying

The shift toward online automotive aftermarket purchasing is opening new distribution opportunities for trailer tire manufacturers and retailers.

The Auto Care Association’s 2025 Joint E-commerce Trends and Outlook Forecast projected U.S. online automotive aftermarket sales of approximately USD 44.6 billion in 2025, including third-party marketplaces, with the channel expected to grow at more than 5% annually through 2030.

Trailer tires are particularly suited to digital purchasing because buyers commonly search by ST tire size, load range, speed rating, trailer application and price rather than simply by vehicle model.

Major online tire platforms increasingly combine product discovery with installation services. Tire Rack connects customers with a network of more than 10,000 installers, while Discount Tire allows shoppers to filter trailer tires by size, load range, brand and price before scheduling installation.

Regional Market Outlook

North America dominates the global Trailer Tires (ST-Type) Market with a 61.10% share, reflecting high RV ownership, extensive recreational boating activity, strong trailer production and a mature replacement ecosystem.

Asia-Pacific accounts for 16.72% of global demand. Regional growth is supported by trailer manufacturing, infrastructure investment, industrial applications and increasing adoption of radial tire technology.

Europe represents 12.09%, supported by recreational and commercial trailer fleets, strict safety requirements and demand for higher-quality replacement products.
