A trailer tire can have plenty of load capacity and still be the wrong buy if its size, pressure requirement, or wheel fit does not match your trailer. The Transeagle ST Radial II pair reviewed here is the TSL15 ST205/75R14 Load Range E version, rated 109/104N and built specifically for trailer use. Its 2,270-pound maximum single-tire load, steel-belted radial construction, full nylon overlay, and highway-focused ribbed tread make it a practical option for compatible boat, camper, utility, and cargo trailers. The key tradeoff is fitment: you still need to confirm the trailer placard, 14-inch wheel compatibility, pressure rating, axle limits, and physical clearance before you order.
Quick Verdict
Rating: 8.6/10, recommended with fitment checks
Best For: Trailer owners who need a pair of ST205/75R14 Load Range E radial tires for paved-road towing
Bottom Line: The Transeagle ST Radial II combines a 2,270-pound maximum single-tire load with reinforced radial construction and a ribbed highway tread. It is a strong value-focused choice when TSL15 matches your trailer, but the Load Range E pressure requirement and 26.14-inch overall diameter must also work with your wheels, valve stems, axle rating, placard, and available clearance.

What Is the Transeagle ST Radial II?
The Transeagle ST Radial II is a highway-focused Special Trailer radial. This review covers the TSL15 ST205/75R14 Load Range E version, sold here as two unmounted tires. It suits a matched two-tire replacement when the trailer placard and wheels support this exact specification.
Transeagle specifies a polyester casing, steel belts, a full nylon overlay, and an enhanced shoulder design intended to promote even wear and heat dissipation. The ribbed tread is aimed at stable paved-road tracking behind the tow vehicle. This is a trailer-only tire, not an all-terrain tire or a substitute for passenger or light-truck tires.
Who Should Buy It?
Best For
- Owners whose trailer placard specifies ST205/75R14 tires and supports Load Range E inflation requirements
- Utility, boat, camper, and equipment-trailer owners who spend most of their towing time on paved roads
- Buyers replacing two matching trailer tires and prioritizing load capacity, straight tracking, and value
Skip If
- Your trailer uses a different tire size, its wheel is not rated for the required pressure, or it cannot accommodate a tire about 26.14 inches in overall diameter
- You need tires for a car, pickup, driven axle, or frequent off-road use
- You want tires already mounted on wheels or need a clearly stated treadwear warranty
Before You Buy: A higher tire load rating does not raise your trailer’s GVWR or axle rating. Confirm the trailer placard, wheel pressure rating, valve stems, axle limits, fender clearance, and current tire size before ordering.
Fit and Compatibility
The TSL15 measures about 26.14 inches in diameter and 7.99 inches across the section. It is approved for 5.0 to 7.0-inch rim widths, with a 5.5-inch measuring rim. Use those figures to check fender, suspension, and sidewall clearance, but follow the trailer placard first.
Its maximum single-tire rating is 2,270 pounds at 80 psi cold. Two tires do not automatically create a usable 4,540-pound axle capacity because the lowest-rated wheel, hub, axle, suspension, frame, or certification value controls the system.
Confirm 109/104N and part number TSL15, since Transeagle sells lower-load versions in the same size. Compare details on the official ST Radial II size chart.
Fit Tips Before You Buy
- Match the full sidewall code, not just the 14-inch wheel diameter. ST205/75R14, 109/104N, Load Range E, and TSL15 identify this specific version.
- Check the wheel’s pressure rating before assuming it can support a Load Range E tire at its maximum 80 psi rating.
- Compare the 26.14-inch overall diameter and 7.99-inch section width with your existing tire to verify fender, suspension, and neighboring-tire clearance.
- Use the trailer placard and manufacturer guidance as the final authority for approved tire size and inflation.
Materials and Build Quality
Steel belts help the tread area resist distortion under load, while the polyester casing and full nylon overlay reinforce the tire body. Transeagle says the enhanced shoulder design is intended to promote even wear and improve heat dissipation, both useful traits during sustained highway towing.
That construction cannot protect an overloaded or underinflated trailer. The tire has a black sidewall, is not run-flat, and carries a listed 7/32-inch tread depth.
Tread Design, Handling, and Wear
The symmetric ribbed tread supports straight tracking, while circumferential grooves help move water away from the contact area on wet pavement. This is an all-season highway trailer design, not a mud tire or a dedicated winter tire.
Even wear still depends on alignment, suspension condition, load balance, and correct inflation. Bent axles or overloaded cargo can create wear that the tread pattern cannot correct.
Installation and Setup
These are loose tires, so professional mounting is the safest choice. A technician can confirm the 5.0 to 7.0-inch approved rim-width range, wheel pressure rating, valve-stem suitability, bead condition, balance, and rim damage before the tire is put into service.
Use matching tires on the same axle. Avoid mixing this 109/104N Load Range E model with a lower-rated or different construction unless the trailer or tire manufacturer approves it. Follow the trailer maker’s cold inflation and lug-torque procedures after installation.
Pro Tip: Before mounting, photograph the DOT date code and tire sidewall markings, then save the order record. That gives you a clear reference for tire age, exact model, load range, and any future warranty or recall check.
How It Performs in Real Use
For Utility and Equipment Trailers
The high single-tire load rating gives compatible utility and equipment trailers useful headroom. The ribbed tread favors straight highway tracking, but secure and balance the cargo because tire capacity cannot correct poor weight distribution.
For Boat Trailers
The radial construction suits road travel to and from the launch. After saltwater use, rinse trailer hardware as directed and check pressure and sidewalls, especially after long storage.
For Campers and Weekend Towing
On compatible campers, the reinforced casing and ribbed tread support steady loaded travel. Check pressure cold before departure and inspect for unusual heat, vibration, or bulging during stops.
For Long Highway Trips
The N speed symbol is part of the 109/104N service description, but it is not a recommendation to tow at the tire’s maximum speed capability. Your safe towing speed can be lower because the trailer, tow vehicle, load, weather, road conditions, law, and manufacturer guidance all matter. Stop for pressure loss, vibration, visible damage, or a sudden change in trailer behavior.
What People Say
Available buyer feedback tends to emphasize stable tracking, load support, and value. Treat those comments as secondary evidence because your result still depends on correct pressure, alignment, load balance, suspension condition, and exact fitment.
Some buyers also note that a two-tire order may arrive as separate packages. Track both shipments and inspect each tire’s size, load range, service description, and condition before scheduling installation.
Overall Sentiment: Positive
Pros and Cons
Pros
- 2,270-pound maximum single-tire load rating for compatible Load Range E trailer setups
- Steel belts, polyester casing, and full nylon overlay support shape retention and durability
- Symmetric ribbed tread promotes straight tracking and even pressure distribution
- Fits approved 5.0 to 7.0-inch-wide 14-inch rims
- Pair packaging is convenient when you need two matching replacement tires
Cons
- Trailer use only, with no suitability for cars, pickups, or driven axles
- Load Range E operation may require wheels and valve stems rated for higher cold pressure
- Rims are not included, and the two tires may arrive in separate shipments
Maintenance and Towing Safety
Check every tire, including the spare, when cold before long trips and during regular inspections. Use the trailer manufacturer’s approved inflation guidance for the installed tire and load. The tire’s 80 psi figure is the listed maximum pressure for this Load Range E specification, not a universal pressure setting for every trailer.
Inspect for cuts, cracks, bulges, punctures, exposed cords, uneven wear, bent wheels, loose hardware, and suspension problems. Repeated pressure loss or vibration requires professional inspection.
Use the DOT code to track tire age. Review NHTSA TireWise safety information and follow replacement guidance from the trailer and tire manufacturers.
Is It Worth the Price?
The Transeagle is a value-oriented option that combines Load Range E capacity, reinforced construction, and pair packaging in a 14-inch size. It offers strong value when your trailer already uses this exact specification.
Value drops if you also need higher-pressure wheels, valve stems, or other hardware, or if you prefer a premium brand with a clearly stated long-term materials warranty.
How It Compares to Alternatives
The Goodyear Endurance ST205/75R14 is a premium Load Range D alternative with a 2,040-pound maximum single-tire load, 65 psi maximum inflation pressure, 8/32-inch tread depth, and a published replacement limited warranty. The Carlstar Radial Trail HD is another established ST205/75R14 option sold in Load Ranges C and D.
Choose the Transeagle when you specifically need the TSL15 Load Range E specification and value-focused pair packaging. The best tire is still the one matching the trailer’s certified size, pressure, wheel, capacity, and clearance.
Frequently Asked Questions
Will these tires fit my trailer?
They fit only when your trailer and wheels support the ST205/75R14 size, approved 5.0 to 7.0-inch rim width, Load Range E pressure requirements, and about 26.14 inches of tire diameter. Confirm the trailer placard, wheel markings, axle rating, and physical clearance before buying.
Does the pair include rims?
No. The package contains two unmounted trailer tires. Budget for professional mounting, suitable valve stems, balancing if recommended, and replacement wheels if your current rims are damaged or not rated for the required pressure.
Can I use them on a pickup or light truck?
No. These are Special Trailer tires and are marked for trailer use. They are not designed to replace passenger or light-truck tires on steering, driven, or braking axles.
Should I inflate them to 80 psi?
Eighty psi is the listed maximum pressure for this Load Range E tire. Use the pressure specified by the trailer manufacturer for the approved tire and load configuration, and never exceed the pressure rating of the wheel, valve stem, or other components.
Does a pair support 4,540 pounds?
Two tires have a combined theoretical single-service rating of 4,540 pounds at the required cold pressure, but that number does not override your axle, wheel, hub, suspension, or trailer GVWR. Your usable capacity is always limited by the lowest-rated part of the system.
Can I mix these with Load Range D tires?
Avoid mixing different load ranges, constructions, or significantly different tread patterns on the same axle unless the trailer or tire manufacturer approves the setup. Matching tires help keep load response, diameter, and handling more consistent.
How often should I check trailer tire pressure?
Check pressure cold before long trips and at least monthly during active use. Inspect the tread, sidewalls, spare, valve stems, wheels, and lug hardware at the same time, and stop using a tire that shows damage or repeated pressure loss.
Who should skip this tire?
Skip it if your placard calls for another size, your wheels cannot support the required pressure, you lack adequate clearance, or you need tires for a vehicle rather than a trailer. It is also a poor match for frequent off-road travel or buyers who want pre-mounted wheel assemblies.
Why Buyers Choose
Buyers choose the Transeagle ST Radial II TSL15 when they need a trailer-specific ST205/75R14 tire with Load Range E capacity, a 109/104N service description, and reinforced radial construction. The pair format simplifies a two-tire replacement, while the ribbed tread and full nylon overlay target stable highway towing and controlled wear.
The strongest reason to buy is the combination of verified dimensions and higher load capacity in a common 14-inch trailer size. The strongest reason to pause is compatibility: the tire only delivers that benefit when the rest of the trailer system is rated and set up for it.
The Bottom Line
The Transeagle ST Radial II pair is a strong value choice for trailer owners who specifically need the TSL15 ST205/75R14 109/104N Load Range E specification. Buy it for its 2,270-pound single-tire capacity, reinforced construction, and highway-focused tread, but skip it if your wheels, trailer placard, axle, clearance, or use case do not match.
