The Carlstar Radial Trail HD is a specialty all-season trailer tire engineered for drivers who need dependable performance and durability for towing RVs, utility, boat, horse, and cargo trailers. Designed specifically for trailer use (not for passenger vehicles), it combines a robust radial construction, heat-resistant compound, and an all-season tread pattern to deliver stable handling, strong load-carrying capacity, and long tread life. With even-wearing tread design and low rolling resistance, the Radial Trail HD is built to handle long highway hauls and demanding towing conditions with confidence.

Radial construction for added strength, durability, and stability under load
-
Optimized tread pattern for even wear and long tread life
-
Heat-resistant compound designed to withstand high temperatures during long hauls
-
Good traction and handling in dry, wet, and light winter conditions
-
Low rolling resistance to support smoother towing and fuel efficiency
-
Commonly used on RVs, boat, horse, stock, and utility trailers
Technology
- All-Season Tread Design: Symmetrical, deep tread pattern is engineered to provide consistent road contact and reliable traction in changing weather, enhancing stability and control while towing.
- Heat-Resistant Rubber Compound: Specialized compound is formulated to resist heat build-up on long highway runs, helping protect against premature wear, tread separation, and performance loss under heavy loads.
- Even-Wear Tread Geometry: Tread design is optimized to distribute driving and load forces evenly across the contact patch, helping eliminate irregular wear patterns and extend overall tire life.
- Reinforced Radial Construction: High-tensile belt package and radial carcass increase puncture resistance and structural integrity, improving load durability and towing stability for heavy-duty trailer applications.
The Carlstar CSL 16 is a heavy-duty, all-steel radial trailer tire designed for large equipment and extremely heavy loads. Built specifically for high-speed trailer applications (not for passenger vehicles), it combines an industrial highway tread design with an all-steel carcass to deliver exceptional load-carrying capacity, stability, and durability. With ratings up to 4,400 lbs per tire and an all-season highway pattern, the CSL 16 is ideal for demanding boat, cargo, horse, livestock, and specialty trailers that spend serious time on the road.
Key Highlights
-
All-steel radial highway trailer tire (ST), not approved for passenger or light truck use
-
Engineered for large equipment and extremely heavy loads (up to ~4,400 lbs in select sizes)
-
Industrial highway tread design for long service life in high-mileage towing
-
Five-rib tread pattern with in-block siping for improved dry, wet, and light winter traction
-
Robust construction for enhanced puncture resistance and load durability
-
Wide circumferential grooves to help evacuate water and slush and resist hydroplaning
-
Ideal for boat, cargo, horse & livestock, specialty trailers, and towable utilities
Technology
-
All-Steel Body Construction: Full steel carcass is engineered to maximize structural strength and load-carrying capability, supporting very high towing capacities and improving durability under heavy, sustained loads.
-
Industrial Highway Tread Design: Ribbed highway pattern is optimized to distribute load evenly across the contact patch, promoting even wear, long tread life, and stable tracking at highway speeds.
-
Five-Rib Pattern with In-Block Siping: Multiple ribs and strategically placed sipes help increase the number of biting edges, improving grip and braking on dry and wet pavement, as well as enhancing traction in light winter conditions.
-
Wide Circumferential Grooves: Deep, wide grooves are designed to quickly evacuate water and slush from the footprint, reducing the risk of hydroplaning and helping maintain stability in adverse weather.
-
Heavy-Duty Load Ranges (F–G): High load-range construction supports demanding commercial and recreational towing, providing stability and confidence for trailers that operate at or near maximum capacity.
The Carlstar Sport Trail is a specialty highway all-season trailer tire designed for drivers who need durability, stability, and safe performance for towable utility, boat, horse, stock, and cargo trailers. Built with a bias-ply construction that delivers radial-like capability, it combines an endurance-focused tread and contour design, rugged sidewalls, and a low-rolling-resistance compound to handle long hauls and frequent towing. With wet-traction features and a profile tuned to manage heat build-up, the Sport Trail is made to keep trailers tracking confidently behind the tow vehicle in a wide range of conditions.
Key Highlights
-
Highway terrain all-season trailer tire (not approved for passenger vehicles)
-
Bias-ply construction with a “radial-look” profile for strength and stability
-
Tread and contour engineered to reduce heat build-up and increase endurance
-
Rugged sidewall helps protect against curbing, punctures, and other damage
-
Lower rolling resistance compound to support fuel-efficient towing
-
Zigzag/channeled grooves designed to improve wet traction and hydroplaning resistance
-
Ideal for utility, boat, horse & livestock, cargo, and other specialty trailers
Technology
-
Endurance-Focused Tread & Contour: The tread shape and internal contour are designed to spread load and heat more evenly, helping to reduce heat build-up at highway speeds and extend tire life under sustained towing.
-
Bias-Ply Construction with Radial-Like Capability: Multiple cross-plies in the carcass provide strong structural support and sidewall toughness, while the overall profile is tuned to deliver stable tracking and smooth towing similar to a radial tire.
-
Rugged Sidewall Design: Reinforced sidewall structure is built to resist curb scuffing, bruising, and punctures, adding protection in tight maneuvers and rough loading environments.
-
Low Rolling Resistance Compound: Specialized rubber formulation is engineered to decrease rolling resistance, which can contribute to cooler running temperatures and improved fuel efficiency for the tow vehicle.
-
Wet-Traction Grooving: Zigzag and circumferential grooves help evacuate water from the contact patch, enhancing grip and reducing the risk of hydroplaning on wet roads while towing.
