A trailer tire has to carry its share of the loaded trailer without building excess heat, losing pressure, or creating unstable tracking. The Transeagle ST Radial II reviewed here is the ST205/75R14 Load Range E variant, manufacturer part TSL15, built specifically for trailer use. Its main strengths are a 2,270-pound maximum single-tire load rating, an 80 PSI maximum pressure, steel-belted radial construction, and an N speed rating. Its main limitation is fitment: a 14-inch ST205/75R14 tire cannot replace an ST205/75R15 tire, even when the width and aspect ratio look similar.
Quick Verdict
Rating: Recommended with caveats, 8/10
Best For: Owners of campers, boat trailers, utility trailers, and cargo trailers that specifically require an ST205/75R14 Load Range E tire.
Bottom Line: The Transeagle ST Radial II TSL15 provides high load capacity, radial highway stability, and a full nylon overlay at a value-focused position. Buy it only after matching the tire size, load range, rim width, cold-pressure requirement, and trailer placard.

What Is the Transeagle ST Radial II?
The Transeagle ST Radial II is an ST-class radial tire made for trailer axles rather than powered passenger vehicles. The TSL15 version uses the ST205/75R14 size, Load Range E construction, a 10-ply rating, and a 109/104N load and speed description.
The manufacturer lists a full nylon overlay across the ST Radial II line. That added cap layer supports casing strength and helps the tire hold its shape under sustained trailer loads. The tire still depends on correct pressure, wheel compatibility, balanced loading, and regular inspection to deliver that benefit.
Who Should Buy It?
Best For
- Your trailer placard or approved replacement specification calls for ST205/75R14 and Load Range E.
- You need a tire-only replacement for a compatible 14-inch wheel that falls within the 5.0- to 7.0-inch approved rim-width range.
- You tow a camper, utility trailer, cargo trailer, or boat trailer mainly on paved roads.
Skip If
- Your wheel is 15 inches or your required tire code is ST205/75R15.
- You need a pre-mounted tire-and-wheel assembly rather than a loose tire.
- You need a dedicated winter, mud, or aggressive off-road trailer tire.
Fit and Compatibility
Fitment starts with the complete size code, not the first three numbers. ST205/75R14 means a special trailer tire with a nominal 205-millimeter section width, a 75 aspect ratio, radial construction, and a 14-inch wheel diameter. A matching ST205/75R15 uses a 15-inch wheel and will not mount on the same rim.
You also need to match the load range, wheel pressure rating, valve stem, rim width, and trailer certification label. The TSL15 is approved for 5.0- to 7.0-inch rims and is measured on a 5.5-inch rim. A tire shop should confirm the wheel is sound and rated for the required cold pressure before mounting.
Pro Tip: Photograph the existing tire sidewall, wheel markings, and trailer certification label before ordering. Compare the full tire code, load range, maximum cold pressure, and rim diameter with the selected Amazon variant at checkout.
Build Quality and Load Support
The TSL15 combines steel-belted radial construction with Load Range E strength and a 10-ply rating. Its published maximum is 2,270 pounds per tire in single-wheel service or 1,980 pounds per tire in dual-wheel service, each at the specified maximum cold pressure.
Those figures are tire limits, not permission to exceed your trailer’s axle rating, gross vehicle weight rating, wheel rating, or cargo limit. The safe system capacity is controlled by the lowest-rated component. More tire capacity does not increase the certified capacity of the axle, wheel, hub, or trailer frame.
Tread Design and Wet-Road Handling
The ST Radial II uses a symmetric, non-directional highway tread. Continuous rib sections support straight tracking, while circumferential grooves provide paths for water to leave the contact area on wet pavement.
This design suits normal highway towing in dry and rainy conditions. It does not turn the tire into a severe-snow or off-road model. Reduce speed for rain, standing water, crosswinds, rough pavement, and changing trailer behavior, even when the tire’s speed symbol permits a higher laboratory-rated speed.
Highway Stability and Heat Management
Radial construction generally flexes differently from a bias-ply trailer tire and is well suited to sustained paved-road travel. The steel belts and nylon overlay help the casing resist distortion under load, which supports steady tracking when the trailer is correctly loaded and aligned.
Pressure loss and overload create extra flex and heat. Check pressure when the tires are cold, inspect every tire and the spare before long trips, and stop if you notice vibration, rapid pressure loss, a bulge, exposed cord, or unusual heat at one wheel position.
How It Performs in Real Use
For Camper Towing
For a camper that requires ST205/75R14 Load Range E tires, the TSL15 offers useful load support and a highway tread. Manage cold pressure, cargo balance, and tire age carefully.
For Utility and Cargo Trailers
The 2,270-pound single-tire maximum suits demanding service, but the trailer must stay within its axle and gross weight ratings. Balance and secure changing cargo before travel.
For Boat Trailers
The radial casing suits paved trips to ramps and storage areas. Inspect the tire, valve stem, wheel, and hub area regularly, especially after long outdoor storage.
For Spare-Tire Use
Use it as a full-size spare only when size, load range, wheel, and pressure requirements match. Keep it inflated and check the DOT date code as well as visible condition.
Mounting and Setup Tips
This listing is for a loose tire, so safe installation requires more than placing an order. Use a qualified tire shop with equipment for trailer tires and ask the technician to inspect the wheel bead seat, valve stem, rim rating, and tire sidewall before inflation.
- Confirm the wheel diameter and approved rim width before the tire is mounted.
- Use a valve stem and wheel rated for the required pressure.
- Ask whether balancing is recommended for your highway trailer application.
- Set cold pressure according to the trailer manufacturer’s placard and applicable load information, without exceeding the tire or wheel maximum.
- Torque the wheel fasteners in the correct pattern and recheck them at the interval stated by the trailer or wheel manufacturer.
- Inspect clearance around the fender, suspension, and neighboring tire before the first loaded trip.
Compatibility and Safety Notes
This is an ST trailer tire. Do not install it on a passenger car or light truck as a casual substitute for the tire type specified by the vehicle manufacturer. Do not mix radial and bias-ply construction, different sizes, or materially different load ranges on the same axle unless a qualified tire professional and the trailer manufacturer approve the setup.
The 80 PSI figure is the tire’s maximum listed pressure, not a universal inflation target. Use the trailer manufacturer’s recommended cold pressure and confirm that the wheel and valve stem can handle it. The NHTSA tire-safety guidance also recommends cold-pressure checks, regular tread and damage inspections, and attention to tire age and the DOT date code.
What People Say
Retailer feedback for this size is generally favorable, with buyers often mentioning value, load rating, and use on campers or utility trailers. Some also note firm beads, which supports using a professional installer and inspecting the delivered tire before mounting.
Overall Sentiment: Positive, with fitment and installation caution
Pros and Cons
Pros
- Load Range E and a 10-ply rating suit trailers that specifically require this capacity class.
- Manufacturer-rated 2,270-pound maximum single-tire load at up to 80 PSI.
- Steel-belted radial construction and full nylon overlay support casing strength and highway stability.
- Symmetric, non-directional tread fits normal wet and dry paved-road towing.
- Common ST205/75R14 dimensions make it a practical tire-only replacement when all fitment details match.
Cons
- The 14-inch tire will not fit a 15-inch wheel, despite the similar ST205/75 size wording.
- The package is tire only, so you still need a compatible wheel, valve stem, mounting, and possible balancing.
- It is intended for highway trailer use, not severe snow, deep mud, or aggressive off-road work.
Key Benefits
- Published TSL15 dimensions make sidewall, wheel, and placard comparison straightforward.
- Load Range E gives compatible trailers more capacity than lower load-range versions of this size.
- The steel-belted radial casing and full nylon overlay support paved-road load stability.
- The 5.0- to 7.0-inch approved rim range fits several common 14-inch trailer wheels.
Why Owners Choose It
Owners choose this version when they need ST205/75R14 sizing, Load Range E capacity, and a tire-only replacement for a sound, pressure-rated wheel. Its value depends on an exact match; a different size, wheel rating, or pressure requirement calls for another tire.
Is It Worth the Price?
The Transeagle ST Radial II sits in the value-focused part of the trailer-tire market. It is worth considering when you need the verified TSL15 specifications and plan to use an existing compatible wheel.
You get Load Range E capacity, a steel-belted radial casing, a full nylon overlay, and a highway tread without paying primarily for a premium brand name. The tradeoff is that the tire-only purchase still requires professional installation, and the value disappears if the Amazon selector, wheel, or trailer placard does not match.
How It Compares to Alternatives
The Goodyear Endurance ST205/75R14 is a premium U.S.-made option with Load Range D, a 2,040-pound maximum load, 65 PSI maximum pressure, and published warranty terms. It may suit buyers who value brand support more than the Transeagle’s higher Load Range E capability.
The Carlisle Radial Trail HD is another established ST205/75R14 Load Range D highway radial. Compare load range, pressure, wheel requirements, warranty, and delivered date code. Choose TSL15 when Load Range E is required and its specifications match exactly.

Frequently Asked Questions
Is this tire ST205/75R14 or ST205/75R15?
The verified TSL15 variant is ST205/75R14 and fits a 14-inch wheel. A product image or other variant may show ST205/75R15, so confirm the selected Amazon option and the delivered sidewall before mounting.
Can I use it on a passenger car or truck?
No. This is an ST tire intended for trailer service. Use the tire type, size, load rating, and pressure specified by the passenger vehicle or trailer manufacturer.
Does it come with a wheel?
No. The listing is for the tire only. You need a compatible 14-inch trailer wheel, a suitable valve stem, and professional mounting.
What does 109/104N mean?
The first two numbers are the load indexes for single- and dual-wheel service, and N is the speed symbol. The manufacturer publishes maximum loads of 2,270 pounds in single service and 1,980 pounds in dual service for TSL15, but your trailer may have lower operating limits.
Should I inflate it to 80 PSI?
Not automatically. Eighty PSI is the tire’s listed maximum cold pressure. Follow the trailer manufacturer’s pressure recommendation and confirm that the wheel and valve stem are rated for that pressure.
Is Load Range E better than Load Range D?
Load Range E provides a higher published load and pressure capability in this size, but it is only better when your trailer, wheel, and valve stem are compatible. Do not use a higher load range to justify exceeding the trailer’s certified axle or gross weight rating.
Can I tow in snow with it?
It is sold as an all-season highway trailer tire, so it can handle normal seasonal road use. It is not a dedicated winter tire for deep snow, severe ice, or demanding mountain conditions.
What should I inspect when the tire arrives?
Check the size, TSL15 part number, load and speed markings, maximum pressure, DOT date code, bead condition, and sidewalls. Do not mount a tire with shipping damage, bulges, exposed cords, or markings that do not match your order.
The Bottom Line
The Transeagle ST Radial II TSL15 is a solid value choice for a trailer that specifically requires ST205/75R14 Load Range E tires. Its 2,270-pound maximum single-tire load, steel-belted radial casing, and full nylon overlay support demanding highway trailer use, but correct size, wheel rating, cold pressure, and installation are essential. Skip it when you need a 15-inch tire, a mounted wheel package, or a tire for severe winter or off-road conditions.
