A trailer tire can have the right wheel diameter and still be the wrong choice if its size, load specification, or intended service does not match your trailer. The Nebula ST Radial N’ 001 reviewed here is the ST175/80R13, 96/92L, Load Range D, 8-ply-rated version made for trailer use. It combines radial construction with a symmetrical highway tread and is sold as one loose tire, not a mounted wheel-and-tire assembly. This review helps you decide whether its fitment, load specification, and highway-focused design suit your trailer before you order.
Quick Answer
The Nebula ST Radial N’ 001 is a reasonable budget-oriented option when your trailer specifically calls for an ST175/80R13 Load Range D tire. The current listing identifies a 96/92L designation, 1,565-pound listed load capacity, 5-inch rim width, and 8-ply rating. You still need to confirm the trailer placard, wheel rating, valve stem, clearance, and required cold inflation pressure because a 13-inch wheel alone does not establish compatibility.
Quick Verdict
Rating: 8.0/10, recommended with fitment caveats
Best For: Owners of compatible utility, cargo, boat, or small recreational trailers that require ST175/80R13 Load Range D tires
Bottom Line: The trailer-specific radial design, 8-ply-rated Load Range D construction, and highway tread make this a practical replacement for the exact applications it fits. The tradeoff is narrow compatibility, so you should verify the full tire code and wheel specifications instead of buying by rim diameter alone.

- You receive one loose tire. A wheel, mounting, balancing, and any needed valve-stem work are separate.
What Is the Nebula ST Radial N’ 001?
The Nebula ST Radial N’ 001 is a radial tire made specifically for trailer service. In this version, ST175/80R13 identifies a special-trailer tire with a 175-millimeter nominal section width, an 80-series aspect ratio, radial construction, and a 13-inch rim diameter. It is not intended as a passenger-car or light-truck replacement tire.
The current product listing identifies model number NBST69252-TH, a 96/92L designation, Load Range D, and an 8-ply rating. It also lists a symmetrical tread, 5-inch rim width, 24-inch tire diameter, 19-pound item weight, and 1,565-pound load capacity. These details make the tire easier to compare with your existing setup, but your trailer placard and wheel limits remain the final fitment check.
Who Should Buy It?
Best For
- Trailers whose placard or manufacturer documentation specifies ST175/80R13 tires.
- Setups approved for Load Range D and a wheel that supports the required tire load and pressure.
- Routine paved-road towing with compatible utility, cargo, boat, or small recreational trailers.
Skip If
- Your trailer requires another tire size, load index, speed symbol, rim width, or load range.
- You need a tire specifically documented for severe-snow or dedicated off-road service.
- You want a pre-mounted wheel-and-tire assembly instead of one loose tire.
Before You Buy: Match the full tire code and trailer requirements, then confirm wheel width, wheel load rating, valve-stem pressure rating, fender clearance, and suspension clearance. A tire that fits a 13-inch rim is not automatically correct for every trailer using 13-inch wheels.
Fitment, Size, and Load Range
Fitment is the most important buying factor. Compare ST175/80R13, 96/92L, Load Range D, and the listed 5-inch rim width with the trailer placard, owner’s manual, existing tire sidewall, axle rating, and wheel specifications. You should also confirm that the tire’s listed 24-inch diameter leaves adequate clearance around the fender and suspension throughout normal trailer movement.
Load Range D and an 8-ply rating describe the tire’s strength category. An 8-ply rating does not necessarily mean the casing contains eight literal fabric plies, and a higher tire load rating does not increase the trailer’s GVWR, GAWR, wheel rating, or hitch rating. Use the lowest applicable component limit and have a qualified trailer-tire installer confirm the setup when ratings do not clearly match.
Pro Tip: Photograph the trailer placard, current tire sidewall, wheel markings, and valve stem before shopping. Comparing those details side by side helps you catch a wrong load range, speed symbol, rim specification, or tire size before mounting makes a return more difficult.
Construction and Durability
The Nebula uses radial construction and is described as a semi-steel trailer tire. Its reinforced structure and ribbed highway-oriented tread are intended to maintain the tire’s shape and steady road contact under normal trailer loads.
Durability still depends on correct cold inflation, load distribution, storage, tire age, wheel condition, and road damage. A Load Range D tire cannot correct bent wheels, worn bearings, misaligned axles, overloaded cargo, or sidewall cracking. Inspect the entire towing system instead of treating a stronger tire rating as a fix for another mechanical problem.
Highway Handling and Stability
The symmetrical, ribbed tread is designed for highway trailer service and steady paved-road contact. When the tire is correctly mounted, inflated, and matched with the tire on the other side of the axle, that layout supports predictable straight-line towing rather than aggressive cornering performance.
No trailer tire can eliminate sway by itself. Excess speed, crosswinds, poor tongue weight, rear-heavy cargo, incorrect hitch setup, worn suspension parts, and mismatched tires can all contribute to instability. Treat the tire as one part of a properly set up trailer rather than a cure for sway.
Wet, Dry, and Cold-Weather Traction
The listing describes the Nebula as an all-season highway tire. Its circumferential grooves and ribbed tread layout are intended for normal paved-road use in dry and wet conditions, but wet traction decreases as tread wears and speed rises. Regular tread and pressure checks matter more than the all-season label alone.
All-season does not mean dedicated winter performance. No severe-snow certification was confirmed for this model during this review. If you regularly tow through snow, ice, mountain passes, or jurisdictions with winter-tire requirements, choose equipment suited to those conditions and follow local rules.
How It Performs in Real Use
Utility and Cargo Trailers
For a utility or cargo trailer already approved for ST175/80R13 Load Range D tires, the Nebula provides a trailer-specific radial option with a 1,565-pound listed load capacity. That rating only helps when the axle, wheel, valve stem, and trailer ratings also support the load and required inflation.
Boat Trailer Use
The highway tread suits paved trips to and from a launch when the size and ratings match your boat trailer. Water exposure makes inspection of the wheel, valve stem, hub, and bearings especially important because tire load range cannot compensate for corrosion, bearing neglect, or damaged hardware.
Long Highway Trips
Radial construction and a ribbed highway tread make sense for sustained paved-road towing. Before departure, check cold pressure, tread condition, sidewall damage, lug torque, wheel condition, and the spare. After the first part of a long trip, inspect the trailer for unusual heat, vibration, visible damage, or pressure loss.
Seasonal Storage
During long storage periods, protect the tire from prolonged sunlight, standing water, petroleum products, and unnecessary concentrated loads. Check the sidewalls, tread, valve stem, and date code before the next towing season because trailer tires can age even when tread depth still looks usable.
Setup and Inspection Tips Before Towing
- Confirm the wheel specifications: Make sure the wheel diameter, width, load rating, and pressure capability are suitable for this tire and your trailer.
- Verify the valve stem: The valve stem must support the pressure required by the approved tire-and-trailer setup.
- Match tires on the axle: Use compatible size, construction, load range, and similar wear across the same axle.
- Set cold pressure correctly: Follow the trailer placard and tire manufacturer’s load guidance before driving, not after the tire has heated up.
- Check mounting and balance: Have the wheel inspected for damage, correct bead seating, balance, and proper lug-nut torque.
- Load the trailer correctly: Stay within all trailer and axle ratings and maintain appropriate tongue weight rather than loading heavily behind the axle.
- Inspect age and condition: Check the DOT date code, tread, sidewalls, valve stem, and spare for cracks, bulges, punctures, or uneven wear.
Common Mistakes to Avoid
- Buying only by the 13-inch rim diameter without matching the complete ST175/80R13 specification.
- Assuming Load Range D lets you carry more than the trailer, axle, hitch, or wheel rating permits.
- Mounting a new tire beside an incompatible or badly aged tire on the same axle.
- Using a passenger-car or light-truck application as a substitute for trailer-specific fitment guidance.
- Ignoring the spare tire, valve stems, bearings, and wheel condition during pre-trip checks.
Compatibility and Safety
This is an ST-designated trailer tire. Do not install it on a passenger car or light truck unless the vehicle and tire manufacturers explicitly approve that application. Also avoid mixing incompatible radial and bias-ply tires on the same trailer axle, and do not exceed the lowest-rated component in the towing setup.
Check tire pressure when the tires are cold and inspect the spare along with the tires carrying the trailer. The National Highway Traffic Safety Administration’s tire-safety guidance emphasizes correct inflation, load limits, tire condition, and proper sizing as core tire-safety practices.
Pros and Cons
Pros
- Trailer-specific ST radial construction for compatible setups.
- Load Range D with an 8-ply rating and 1,565-pound listed load capacity.
- Symmetrical highway-focused tread suited to routine paved-road towing.
- Current listing provides useful fitment details, including a 5-inch rim width and 24-inch listed tire diameter.
- Single-tire format works well when your existing compatible wheel is still serviceable.
Cons
- Limited to trailers that match the ST175/80R13 size and required ratings.
- Tire only, so a compatible wheel, valve stem, mounting, and balancing are separate costs when needed.
- No severe-snow certification was confirmed, and independent long-term test data is limited.
Is It Worth the Price?
The Nebula ST Radial N’ 001 is best viewed as a budget-oriented replacement tire rather than a premium trailer-tire package. It offers strong value for the price when you already have a serviceable, correctly rated wheel and specifically need the ST175/80R13 Load Range D version. The published size, rim-width, load, and construction details also make comparison shopping more straightforward.
Value drops if you need a complete mounted assembly, stronger dealer support, extensive independent testing, or a tire intended for specialized winter or off-road conditions. Include mounting, balancing, valve-stem service, and possible wheel replacement when comparing the total installed cost.
How It Compares to Alternatives
The Transeagle ST Radial II is available in an ST175/80R13 Load Range D version with a 97/93L designation, while the Travelstar Ecopath ST is sold in ST175/80R13 Load Range D versions with a 97/93M designation. Those alternatives can be worth comparing when you want a different load or speed designation within the same general trailer-tire size.
The Nebula makes the most sense when its specific 96/92L, Load Range D configuration matches your trailer and wheel requirements. Do not choose between these tires by brand name alone, because the complete sidewall code, load capacity, speed symbol, wheel requirements, and seller support can differ by exact variant.
Frequently Asked Questions
Does this listing include one tire or a pair?
The listing is for one tire. A wheel or rim is not included, so you may also need mounting, balancing, and a suitable valve stem depending on your current setup.
Will it fit any trailer with 13-inch wheels?
No. Your trailer must be compatible with ST175/80R13 tires, and the wheel must meet the required width, load, and pressure specifications. You also need adequate fender, suspension, and sidewall clearance.
What load capacity is listed for this Nebula tire?
The current product listing shows a 1,565-pound load capacity along with a 96/92L designation and Load Range D. Do not use that number to exceed your trailer’s axle, wheel, hitch, or GVWR limits.
Can it replace a Load Range C trailer tire?
Possibly, but only when the ST175/80R13 size is correct and the wheel, valve stem, trailer, and manufacturer guidance support the Load Range D setup. A higher tire load range does not increase the trailer’s legal or mechanical payload limits.
Is the Nebula ST Radial N’ 001 suitable for cars or trucks?
No for normal use. It is an ST-designated tire intended for trailer service, so passenger cars and light trucks should use tires approved for those vehicles rather than treating this as a substitute.
Is it a good choice for snow?
It is listed as an all-season highway tire, but no severe-snow certification was confirmed. Regular winter towing in snow or ice calls for equipment suited to the expected conditions and local requirements.
What pressure should you use?
Use the cold inflation pressure required by the trailer placard and supported by the tire, wheel, and valve stem. Do not guess from the tire’s appearance, and do not bleed pressure from a warm tire unless instructed by qualified guidance.
What should you check when the tire arrives?
Confirm the brand, model, ST175/80R13 size, 96/92L designation, Load Range D marking, date code, and sidewall condition before mounting. Also compare the tire with your wheel and trailer specifications and review the seller’s current return terms before installation.
The Bottom Line
The Nebula ST Radial N’ 001 earns an 8.0/10, recommended with fitment caveats verdict for owners who need this exact ST175/80R13, 96/92L, Load Range D trailer tire for paved-road service. Its main strengths are trailer-specific radial construction, useful published fitment details, and an 8-ply-rated load specification, while its main limitation is that it only makes sense for a correctly matched trailer and wheel. Skip it when your placard calls for another size or rating, when you need a mounted assembly, or when severe-winter capability is a priority.
