A strong ST175/80R13 trailer tire choice matches your trailer’s required size and load rating, with a complete wheel assembly if you need a direct replacement. This comparison includes 8-ply options, tire-and-wheel sets, and a lighter 6-ply choice, so it serves owners replacing individual tires as well as shoppers needing mounted assemblies. The closest matches to the keyword are the ST175/80R13 products; two lower-ranked listings use ST175/80D13 instead, a different size designation that should not be treated as interchangeable without checking your trailer requirements.
Compare load capacity, rim size, and whether a wheel is included before deciding. Product specifications vary in detail, so confirm fitment and required pressure against your trailer documentation and the tire sidewall.
Free Country Trailer Wheel 8-Ply leads because it is listed as an ST175/80R13 8-ply tire-and-wheel assembly with a 5X4.5-inch pattern, combining the requested tire size with an included 13-inch rim. It suits buyers replacing a mounted wheel rather than sourcing a tire alone. The Free Country listing does not state a load capacity, so compare its sidewall rating with your trailer’s requirements before buying.
If a stated 1,610-pound capacity matters more, consider the ranked Free Country 8-Ply D Spoke assembly or a tire-only option.

Detailed Reviews: Best St175 80R13 Trailer Tires

#1 · Best Overall
1. Free Country 8-Ply D Spoke
- Size: ST175/80R13
- Rim Size: 13 in
- Load Capacity: 1610 lb
Best for: Higher-capacity wheel assemblies.
Why it ranks #1: This ST175/80R13 tire-and-wheel listing specifies 8-ply, load range D, 1,610-pound capacity, and a 5X4.5-inch spoke wheel.
A listed 1,610-pound load capacity distinguishes this Free Country ST175/80R13 tire-and-wheel listing for buyers comparing replacement assemblies by stated capacity. The title adds 8-ply Load Range D details and a 5×4.5-inch bolt pattern, plus a silver-spoke wheel for a defined assembly configuration.
The ST175/80R13 size and 8-ply Load Range D designation help buyers compare the tire with their trailer’s requirements, while the stated 1,610-pound capacity supplies a specific load figure. A 5×4.5-inch wheel pattern identifies the mounting configuration, and the silver-spoke wheel gives the assembly a defined style. Since it is a tire-and-wheel listing, it can suit buyers replacing a complete assembly, provided the wheel pattern and tire size match their trailer.
- 1,610-pound stated load capacity
- ST175/80R13 size
- 8-ply, Load Range D
- 5×4.5-inch silver-spoke wheel
- The 5×4.5-inch wheel pattern restricts fit to trailers using that mounting pattern.
Skip it if you need a 6-ply paired assembly; Free Country ST175/80R13 6PR 91N 5X4.5 Silver Spoke Pk2 is listed with that rating.
This Free Country assembly suits trailer owners replacing a wheel and tire together who need ST175/80R13, 8-ply Load Range D, and the stated capacity. Its wheel pattern is a key boundary; match it to the trailer.

#2 · Best Two-Wheel Set
2. Free Country 8-Ply Silver Spoke
- Size: ST175/80R13
- Rim Size: 13 in
Best for: Ready-wheel replacement buyers.
Why it ranks #2: The exact ST175/80R13 size comes as a pair with 8-ply tires and 13-inch silver spoke wheels; the listing specifies a 5X4.5-inch pattern.
A paired tire-and-wheel package with a 5×4.5-inch bolt pattern gives trailer owners a matched replacement assembly rather than a tire alone. Its ST175/80R13 size and 13-inch silver-spoke wheels define the fit; the listed 8PR rating adds a concrete specification for buyers comparing trailer tire options.
The ST175/80R13 tire size and 13-inch rim make this a direct category match for trailers using that size, while the 5×4.5-inch pattern identifies the wheel mounting configuration to compare with the trailer. Because the title specifies a pair, buyers replacing two assemblies can source them together. Alloy-steel wheel material and the silver spoke style are also stated, helping shoppers distinguish this package from tire-only listings and other wheel finishes.
- Includes two trailer tire-and-wheel assemblies
- ST175/80R13 tire size
- 13-inch alloy-steel wheels
- 5×4.5-inch bolt pattern
- The fixed 5×4.5-inch bolt pattern limits use to trailers with matching wheel mounts.
Skip it if you need a stated load-capacity figure; the Travelstar HF288 listing specifies a 1,610-pound capacity.
Choose this Free Country pair if you need two 13-inch trailer assemblies with the stated 5×4.5-inch pattern and silver spokes. Its fit boundary is specific: verify that pattern and ST175/80R13 size match your trailer before choosing.

#3 · Highest Stated Capacity
3. Grand Ride D207
- Size: 175/80R13
- Rim Size: 13 in
- Load Capacity: 1610 lb
Best for: Scuff-guard tire buyers.
Why it ranks #3: This ST175/80R13 8-ply load-range-D tire lists a 1,610-pound capacity and scuff guard, although a wheel is not listed as included.
A listed scuff guard is the defining feature of this Free Country Prem ST175/80R13 tire, giving buyers a specific protective feature to weigh when choosing a trailer replacement. The listing also identifies 8PR, Load Range D, and a 1,610-pound capacity for specification-based comparisons.
The ST175/80R13 size and Load Range D designation help shoppers compare this tire against a trailer’s existing requirements, while the stated 1,610-pound load capacity supplies a clear figure for checking load needs. Its scuff guard adds a named protective feature around the tire’s side area. As the listing describes a tire rather than a wheel assembly, buyers with worn tires and usable rims can focus on replacement rubber, with mounting handled separately.
- Scuff guard feature
- ST175/80R13 size
- Load Range D, 8PR
- 1,610-pound listed load capacity
- This listing is a tire rather than a complete wheel assembly.
Skip it if you need a rim included with the tire; Free Country ST175/80R13 8PR 97M 5X4.5 is listed as a tire-and-wheel product.
This Grand Ride D207 suits buyers replacing an ST175/80R13 tire who value its stated scuff guard and Load Range D specification. It is a tire-only choice, so it fits best when a compatible wheel is already available.

#4 · Best Tire-Only Pick
4. Travelstar HF288
- Size: ST175/80R13 8PR
- Rim Size: 13 in
- Load Capacity: 1610 lb
Best for: Rated-capacity tire replacements.
Why it ranks #4: This exact-size special trailer tire is an 8-ply option with a stated 1,610-pound load capacity for buyers who do not need a wheel.
The Travelstar HF288 lists a 1,610-pound load capacity, giving trailer owners a specific figure to compare when replacing ST175/80R13 tires. This two-tire set also specifies 8-ply construction and a 97N rating, combining a defined tire size with details useful for matching replacement needs.
The ST175/80R13 size and 8-ply specification help identify whether these tires match a trailer’s current tire requirements, while the stated 1,610-pound capacity provides a load figure for comparison with the trailer’s demands. The 97N marking is also included in the title, giving shoppers another labeled specification to check. Because the product is a set of two tires rather than a wheel package, buyers can reuse suitable rims but must handle mounting separately.
- Set of two tires
- 1,610-pound stated load capacity
- 8-ply construction
- 97N rating
- The package is a tire set, not a tire-and-wheel assembly.
Skip it if you want a paired wheel assembly included; Free Country ST175/80R13 8PR 97M 5X4.5 includes a tire and wheel.
Pick the Travelstar HF288 if your trailer calls for ST175/80R13 tires and the stated capacity and 8-ply details suit your requirements. It is best for buyers with compatible wheels ready, not those seeking complete assemblies.

5. Transeagle ST II
- Size: 175/80R13
- Rim Size: 13 in
- Load Capacity: 1609 lb
Best for: Four-tire replacement sets.
Why it ranks #5: The four-tire listing matches ST175/80R13 and specifies 8-ply construction and 1,609-pound capacity, but includes tires only.
Four tires in one listing make the Transeagle ST II a practical option for buyers replacing a full set rather than sourcing tires individually. The ST175/80R13 size, 8-ply construction, and 1,609-pound listed capacity give shoppers concrete details for checking trailer requirements.
The four-tire quantity lets buyers source a complete matching set in one product, while the ST175/80R13 size and 8-ply construction help with specification comparisons. A listed 1,609-pound load capacity provides a figure to evaluate against the trailer’s needs. Transeagle also states all-season use and cites handling, load durability, and traction as product attributes. These tires are supplied without wheels, so existing rims or separate wheel sourcing are part of the installation plan.
- Four tires in the listing
- ST175/80R13 size
- 8-ply construction
- 1,609-pound stated load capacity
- Tire-only package; wheels are not included.
Skip it if you need wheels included for a two-tire replacement; the Garvee ST175/80D13 2-Pack includes tire-and-rim assemblies.
Choose this Transeagle set if you need four ST175/80R13 tires and its stated capacity and 8-ply details align with your trailer. It suits buyers handling wheel selection separately, since the listed components are tires only.

6. Horseshoe ST-King II
- Size: ST 175/80R13 8PR
- Rim Size: 13 in
- Load Capacity: 730 kg
Best for: Heavy-duty tire-only shoppers.
Why it ranks #6: This 8-ply radial matches ST175/80R13 and includes a stated two-year warranty, but its listing says tires only and gives no load capacity.
A stated 730 kg load capacity gives the HORSESHOE LIPIZZAN ST KING II a concrete specification for buyers comparing ST175/80R13 trailer tires. Its 8-ply construction and rim-guard wall add two other defining features, while the tire-only package makes clear that wheels are not part of the purchase.
The 8-ply ST175/80R13 specification identifies the tire size and construction for shoppers replacing a matching trailer tire, and the listed 730 kg load capacity gives a stated figure to compare with the trailer’s requirements. A rim-guard wall is named as a feature, offering a protective design element at the rim area. Since the package explicitly excludes a rim or wheel, installation planning must include an existing compatible wheel or a separate wheel purchase.
- ST175/80R13 size
- 8-ply construction
- 730 kg stated load capacity
- Rim-guard wall feature
- Tires only; a rim or wheel is not included.
Skip it if you need wheels included; the Garvee ST175/80D13 2-Pack listing includes two tire-and-rim assemblies.
This suits trailer owners seeking ST175/80R13 tires with an 8-ply rating and a stated load capacity, especially when compatible wheels are already on hand. It is a tire-only listing, so plan separately for wheel availability.

#7 · Best 6-Ply Assembly
7. Free Country 6-Ply Silver Spoke
- Size: ST175/80R13
- Rim Size: 13 in
Best for: Paired six-ply wheel assemblies.
Why it ranks #7: This exact-size pair includes 13-inch silver spoke wheels and 6-ply tires, a lower-ply assembly choice than the 8-ply matches.
A two-piece package of ST175/80R13 tires with silver-spoke wheels gives buyers a paired replacement assembly in one listing. Free Country specifies 6PR, a 91N rating, and a 5×4.5-inch pattern, letting shoppers compare the tire construction and wheel mounting details against their trailer.
The pair format can simplify replacing two matching trailer assemblies, while the ST175/80R13 size and 6PR rating identify the tire specifications. The title’s 91N marking adds another detail for checking against existing requirements. Free Country lists 13-inch silver-spoke wheels with a 5×4.5-inch pattern, so buyers can assess the mounting configuration before installation. Since the package combines tires and wheels, it differs from tire-only replacement options, but its fixed pattern remains essential to fit.
- Two tire-and-wheel assemblies
- ST175/80R13 size
- 6PR, 91N rating
- 13-inch silver-spoke wheels with 5×4.5-inch pattern
- The assembly’s 6PR rating is lower than the 8PR options listed here.
Skip it if you need an 8PR assembly; Free Country ST175/80R13 8-Ply D 97M 5X4.5 Silver Spoke is listed with 8-ply construction.
Select this Free Country pair if you need two ST175/80R13 assemblies and its 6PR rating and 5×4.5-inch wheel pattern meet your trailer’s requirements. The fixed wheel pattern and stated tire rating are important fit considerations.

8. Roundrule ST Hikee
- Size: 175/80R13
- Rim Size: 13 in
- Load Capacity: 1356 lb
Best for: Six-ply trailer tire shoppers.
Why it ranks #8: This ST175/80R13 special trailer tire lists a 1,356-pound capacity and 6-ply rating, making it a lighter-capacity tire-only alternative.
The Roundrule ST Hikee pairs an ST175/80R13 size with a 6-ply, Load Range C specification, giving buyers a clearly identified option for trailers requiring those details. Its listed 1,356-pound capacity adds a specific load figure to consider alongside the tire’s size and construction.
The 6-ply and Load Range C markings provide construction and range details for comparison with a trailer’s tire requirements, while the ST175/80R13 size identifies the intended tire category. Roundrule lists a 1,356-pound load capacity, helping buyers assess the tire against their load needs. The listing describes a semi-steel tire and includes the tire only, so this option fits replacement workflows where a suitable rim is available and the tire can be mounted separately.
- ST175/80R13 size
- 6-ply, Load Range C
- 1,356-pound stated load capacity
- Semi-steel tire construction
- The listed load capacity is 1,356 pounds, below the 1,610-pound figures on some options here.
Skip it if you require a listed 1,610-pound capacity; the Travelstar HF288 specifies that figure and has 8-ply construction.
The Roundrule suits buyers whose trailer requirements match its ST175/80R13 size, 6-ply Load Range C rating, and stated capacity. Since only the tire is included, have a compatible wheel available for mounting.

9. Garvee D13 White-Rim Set
- Size: ST175/80D13
- Rim Size: 13 in
Best for: Complete white-rim assemblies.
Why it ranks #9: This two-piece tire-and-wheel set includes 13-inch, 5-lug-on-4.5-inch rims and a stated 1,360-pound capacity, but its size is ST175/80D13.
Two complete ST175/80D13 tire-and-rim assemblies, each with a 13-by-5-inch white wheel, make this Garvee set ready for buyers replacing paired trailer wheels. The listing also gives a 5-lug, 4.5-inch bolt pattern, 1,360-pound maximum load, and 50 PSI maximum pressure for comparison.
The included tire-and-rim assemblies simplify paired replacement by supplying both components together, while the 13-by-5-inch wheel and 5-lug, 4.5-inch pattern give buyers specific mounting details to compare. Garvee lists a 1,360-pound maximum load and 50 PSI maximum pressure, useful figures when reviewing trailer requirements. DOT certification is stated, and the modern variable-pitch tread is described as reducing road noise. The ST175/80D13 size remains a fit boundary for tire selection.
- Two complete tire-and-rim assemblies
- 13-by-5-inch white wheels
- 5-lug, 4.5-inch bolt pattern
- 1,360-pound maximum load and 50 PSI maximum pressure
- The ST175/80D13 tire is a D-size listing, not an R-size radial.
Skip it if you need ST175/80R13 radials; the HORSESHOE LIPIZZAN ST KING II is an R-size 8-ply tire, though its rim is not included.
Choose this Garvee pair if you need two complete assemblies and its white 13-by-5-inch rims, bolt pattern, and listed load details suit your trailer. Check the D-size designation carefully; it is not an R-size radial.

10. GarveeTech D13 Black-Rim Set
- Size: ST175/80D13
- Rim Size: 13 in
- Load Capacity: 1360 lb
Best for: Small-trailer wheel replacements.
Why it ranks #10: The two-pack includes 13-inch wheels and lists 1,360-pound capacity, but it is ST175/80D13 rather than the requested ST175/80R13.
This GarveeTech package combines two ST175/80D13 tires with 13-inch rims, giving small-trailer owners complete assemblies in one listing. Its 5-lug, 4.5-inch PCD and 1,360-pound capacity provide useful fit and load details, while the title specifies a 6PR, Load Range C tire.
Two tire-and-rim assemblies can simplify a paired replacement compared with sourcing each component separately, and the listed 5-lug, 4.5-inch PCD identifies the wheel pattern to check against the trailer. The 13-inch rim and ST175/80D13 tire size further define the fit. GarveeTech lists a 1,360-pound capacity and a 6PR Load Range C rating; its tread design is described as supporting grip and stability. Confirm dimensions, including center bore and overall diameter, as the listing advises.
- Two tire-and-rim assemblies
- 13-inch rims with 5-lug, 4.5-inch PCD
- 1,360-pound stated capacity
- 6PR, Load Range C
- The tire is ST175/80D13, not the ST175/80R13 radial size.
Skip it if you specifically need an R-size radial; Travelstar HF288 is listed as ST175/80R13 with 8-ply construction.
This pair fits buyers replacing two assemblies on a small utility or compact trailer when the listed D-size, 13-inch rim, and bolt pattern match. Its boundary is important: it is not the R-size radial specification.

View on AmazonR-type and D-type size labels are not a safe shortcut
Do not assume an ST175/80D13 listing is interchangeable with an ST175/80R13 tire just because the numbers look similar. This group includes eight listings marked ST175/80R13 and two marked ST175/80D13: the Garvee and GarveeTech assemblies. The D-type listings identify different tire construction, and their stated capacities are 1,360 pounds; the R-type products include several 8-ply options with stated capacities around 1,609 to 1,610 pounds.
Those differences do not by themselves establish which tire fits a particular trailer. Check the tire currently specified by the trailer maker, wheel compatibility, and the required load rating before ordering.
Also distinguish a bare tire from an assembly: several products include a rim, while Travelstar, Grand Ride, Transeagle, Horseshoe, and Roundrule are listed as tire-only or do not list a wheel as included. Confirm every dimension and fitment detail with your trailer documentation.
A wheel assembly still needs a hub-fit check
A tire-and-wheel assembly can simplify replacement, but matching the tire size alone does not confirm that its wheel fits your trailer. Free Country’s assembly listings specify a 5X4.5-inch pattern, and the Garvee D-type options also describe 5-lug-on-4.5-inch wheels. GarveeTech specifically advises checking the rim’s PCD and center bore as well as overall tire diameter.
Those details matter because an incorrect bolt pattern or center bore can prevent proper mounting, even when a wheel is 13 inches. The product data does not provide a complete hub-fit specification for every assembly, so do not infer compatibility from the shared rim size.
Before choosing a mounted set, compare the trailer’s manual or existing wheel specifications with the listing. For tire-only choices, check that the existing rim is appropriate for the tire and confirm any required fitment details with the manufacturer.
How to Choose an ST175/80R13 Trailer Tire
Size designation and fit
Start by matching the full size designation on your trailer’s existing tire or documentation, not just the 175/80 numbers. Most choices here are ST175/80R13, while Garvee D13 White-Rim Set and GarveeTech D13 Black-Rim Set are ST175/80D13. Both groups list 13-inch rims, but that shared rim size does not prove the tires are interchangeable.
Assembly listings also vary in wheel details: Free Country specifies a 5X4.5-inch pattern, and Garvee lists 5 lug on 4.5 inches. If you need a mounted replacement, favor a listing with wheel details that match your hub; if you are buying tire-only, verify that your existing wheel suits the tire.
Buyers whose trailer specifies the R-size should prioritize the exact R-size listings.
Load capacity and ply rating
Choose a tire whose load rating meets your trailer’s required load, and check the rating on the tire itself before towing. The listed R-size 8-ply options include 1,609-pound capacity for Transeagle and 1,610 pounds for Travelstar and Grand Ride; Roundrule’s 6-ply tire lists 1,356 pounds. Garvee and GarveeTech list 1,360 pounds but use the D-size designation.
Free Country’s 8-ply assembly listing does not state a capacity in the supplied specifications, so do not assume its rating from ply count alone. Buyers carrying heavier loads should focus on products with stated capacities that meet the trailer’s requirements.
Lighter-duty users may consider a lower-capacity option only when it still satisfies the maker’s rating and the trailer’s total load.
Tire-only or complete assembly
Decide whether you need a tire alone or a tire mounted on a wheel before comparing listings. Free Country’s ST175/80R13 products are listed as tire-and-wheel options, including a two-piece 8-ply set and a two-piece 6-ply set; Free Country 8-Ply D Spoke is also described with a wheel. By contrast, Transeagle explicitly lists tire only, and the Travelstar and Roundrule listings are tires rather than complete wheel sets.
The Garvee options include two tire-and-wheel assemblies, but their size is ST175/80D13. A buyer replacing a tire on a verified compatible rim can focus on tire-only listings.
Someone replacing a damaged wheel as well should compare assembly details, bolt pattern, and center bore, not just the tire size.
Which ST175/80R13 Trailer Tire Should You Choose?
For a replacement assembly with a stated load figure, choose Free Country 8-Ply D Spoke: it matches ST175/80R13, lists 1,610 pounds, and specifies a 5X4.5-inch wheel pattern. If you want a two-wheel set and can confirm its fit, Free Country 8-Ply Silver Spoke includes two 8-ply tire-and-wheel assemblies. For a tire-only replacement, Travelstar HF288 matches the requested size and lists 1,610-pound capacity; Grand Ride D207 is another 8-ply load-range-D option with scuff guard.
Transeagle ST II suits buyers seeking four tires in the exact size, with 1,609-pound capacity. Consider Free Country 6-Ply Silver Spoke or Roundrule ST Hikee only if their lower listed capacity meets your trailer’s requirement.
Avoid choosing the D13 Garvee listings as direct R-size substitutes without verification.

Frequently Asked Questions
How can I confirm the bolt pattern and center bore will fit my trailer hub?
Match the wheel’s bolt pattern and center bore to your trailer hub before ordering. Count the studs and measure the pattern using the correct method for your hub, then check the center-bore measurement in the listing or with the seller. The product titles do not provide every fitment detail, so verify both measurements.
Should trailer tires be replaced in pairs or all at once?
Replace tires on the same axle in pairs when possible, so they have matching size and similar condition. Replace all tires if they are worn, damaged, aged, or do not match the trailer’s requirements. Follow the trailer or tire manufacturer’s guidance, and check that replacement tires have suitable load ratings.
What tire pressure should I use when towing?
Use the cold inflation pressure specified by the trailer or tire manufacturer for your tire and load. Check pressure before towing, when the tires are cold, and do not assume the pressure listed on a tire sidewall is the correct operating target for every setup. The supplied product details do not specify inflation pressure.
How do I know whether a listed load capacity is sufficient?
Check your trailer’s required tire capacity and compare it with the capacity listed for each replacement. The listed capacities vary: some options state 1,610 pounds, while others have different ratings or no capacity stated in the supplied details. Confirm the tire’s sidewall rating and do not exceed the trailer’s requirements.
Should I choose a tire-only replacement or a tire-and-wheel assembly?
Choose a tire-only option if you plan to reuse a compatible wheel and can have the tire mounted appropriately. Choose an assembly if you need a replacement rim as well, but first confirm its bolt pattern and center bore fit your hub. Listings differ, so check whether they include one or more assemblies.
Final Words
For a mounted replacement, the leading Free Country assembly combines the requested tire size with a 5X4.5-inch pattern, but its listing does not state load capacity; verify the sidewall rating before purchase. If a stated 1,610-pound capacity is important, compare the D Spoke assembly or Travelstar tire-only option. For a set, check the Silver Spoke pair’s fit, and avoid treating D13 listings as direct R-size substitutes without verification.
