A strong utility trailer spare tire is a pre-mounted tire and wheel that matches your trailer’s size, bolt pattern, and load needs. These six eCustomRim and Garvee options range from 4.80-12 tires rated for 990 pounds each to ST205/75D15 tires rated for 1,820 pounds, with 13-inch choices in between. Several arrive assembled with valve stems, but the listings differ in wheel pattern, rim size, and whether they describe one assembly or a two-pack.
That makes checking the trailer’s existing tire markings and wheel fitment more important than choosing by diameter alone. The eCustomRim ST205/75D15 white assembly leads as the clearest single-spare choice: its listing specifies one mounted tire and wheel, a common five-lug pattern, and a defined load rating.
Always confirm fit before buying.
The eCustomRim ST205/75D15 White Assembly is the clearest pick for a single utility trailer spare. It includes one pre-mounted tire, white wheel, and valve stem, and its 5-lug-on-4.5-inch pattern fits many common utility and travel trailers. The Load Range C tire is rated for up to 1,820 pounds at 50 PSI.
Confirm the trailer’s tire size, bolt pattern, center bore, and clearance before ordering; those details determine whether this assembly will fit your specific trailer.

Detailed Reviews: Best Utility Trailer Spare Tire
#1 · Best Overall
1. eCustomRim ST205/75D15 White Assembly
- Weight: 36 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
- Wheel Size: 15 in
Best for: Single 15-inch replacement wheel.
Why it ranks #1: The listing confirms one pre-mounted tire, wheel, and valve stem; its 1,820-pound rating and 5-lug-on-4.5-inch pattern suit many utility trailers.
The pre-mounted ST205/75D15 tire, white 15-by-5-inch rim, and valve stem arrive together, so replacing a trailer wheel does not require mounting a tire separately. Its 1,820-pound maximum load rating and 5-on-4.5-inch bolt pattern give buyers concrete capacity and fitment details to check against their trailer.
This single assembly suits a compatible trailer needing a 15-inch wheel and a 5-lug, 4.5-inch bolt pattern; the 3.19-inch center bore adds another useful fitment check. The bias-ply tire has a 27.2-inch overall diameter, Load Range C, and a 50 PSI maximum pressure, with a listed maximum load of 1,820 pounds. Because the tire is already mounted and includes a valve stem, installation can focus on changing the wheel rather than arranging tire mounting.
- One pre-mounted ST205/75D15 tire, white wheel, and valve stem
- 1,820-pound maximum tire load rating
- 15-by-5-inch rim with 5-on-4.5-inch bolt pattern
- 3.19-inch center bore and 27.2-inch overall diameter
- Sold as a single assembly, so replacing a pair requires another wheel.
Skip it if you need two assemblies in one package; the eCustomRim ST205/75D15 black two-pack supplies a pair.
For a utility-trailer owner replacing one compatible 15-inch wheel, this pre-mounted white assembly keeps the swap straightforward. Check the 5-on-4.5-inch pattern, 3.19-inch bore, and tire dimensions against the trailer before choosing it.

- Wheel Size: 15 in
Best for: Silver single 15-inch assembly.
Why it ranks #2: This single 15-inch assembly has the same 1,820-pound rating, 50 PSI maximum, and 5-lug-on-4.5-inch pattern as the leading size.
The silver 15-inch rim distinguishes this pre-mounted eCustomRim ST205/75D15 assembly, while its 1,820-pound tire rating supports a substantial trailer-spare role. The included tire, wheel, and valve stem arrive together, enabling a compatible wheel replacement without arranging separate tire mounting.
Its 15-by-5-inch rim uses a 5-lug, 4.5-inch bolt pattern and a 3.19-inch center bore, so buyers can check hub compatibility using the listed measurements. The bias-ply tire has a 27.2-inch overall diameter, Load Range C, and a 50 PSI maximum pressure; its maximum load rating is 1,820 pounds. Since the assembly is pre-mounted, fitting it avoids a separate tire-mounting step, while the silver finish offers a distinct option among the listed 15-inch assemblies.

- 1,820-pound maximum load rating
- 15-by-5-inch rim with 5-on-4.5-inch bolt pattern

Skip it if you need two 15-inch assemblies together; the eCustomRim black ST205/75D15 set includes a pair.
For a trailer owner replacing one wheel, this silver assembly combines a pre-mounted tire with a 1,820-pound maximum rating. Match its 5-on-4.5-inch pattern, 3.19-inch bore, and tire dimensions to the trailer first.

- Weight: 36 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
- Wheel Size: 15 in
Best for: Black 15-inch two-wheel set.
Why it ranks #3: Its 15-inch Load Range C tire carries up to 1,820 pounds; the listing describes mounted assemblies with valve stems, though its package quantity is unclear.
A pair of pre-mounted ST205/75D15 tires on black rims gives this eCustomRim set a clear advantage for owners replacing two compatible trailer wheels at once. Each tire is rated for up to 1,820 pounds, and the 5-on-4.5-inch pattern provides a specific hub-fit reference.
The 15-by-5-inch rims use a 5-lug, 4.5-inch bolt pattern and 3.19-inch center bore, allowing buyers to compare the important mounting dimensions before installation. Each bias-ply tire has a 27.2-inch overall diameter, Load Range C, and 50 PSI maximum pressure, with a maximum load rating of 1,820 pounds. As both assemblies arrive pre-mounted with valve stems, the pair is ready for a wheel change without a separate tire-mounting step.
- Two pre-mounted ST205/75D15 tire-and-wheel assemblies
- 1,820-pound maximum load rating per tire
- Black 15-by-5-inch rims with 5-on-4.5-inch pattern

Skip it if you need a single assembly rather than a pair; the eCustomRim white ST205/75D15 listing is sold as one.
This set fits owners replacing two wheels on a trailer with compatible 15-inch, 5-on-4.5-inch hubs. Its 1,820-pound tire rating and 3.19-inch center bore are useful checks, while the black rims define its appearance.

4. eCustomRim ST175/80D13 Assembly
- Weight: 54 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
- Wheel Size: 13 in
Best for: Matched 13-inch five-lug pair.
Why it ranks #4: The two pre-mounted 13-inch assemblies each support 1,360 pounds and use a 5-lug-on-4.5-inch pattern, useful when that size matches the trailer.
Two pre-mounted ST175/80D13 assemblies with valve stems make this eCustomRim package a ready-to-install pair for compatible trailers. The Load Range C bias-ply tires each carry a 1,360-pound maximum load rating, while their 5-on-4.5-inch pattern identifies the hub layout they require.
Each 13-by-4.5-inch rim has a 3.19-inch center bore and a 5-lug, 4.5-inch bolt pattern, giving buyers key measurements to check before fitting the pair. The tire’s 24.4-inch overall diameter and 50 PSI maximum pressure help distinguish it from other trailer sizes, and its maximum load is 1,360 pounds. With both tires mounted and valve stems included, installation avoids a separate mounting step; confirm the trailer’s hubs and required load capacity.
- Two pre-mounted ST175/80D13 assemblies with valve stems
- 1,360-pound maximum load rating per tire
- 13-by-4.5-inch rims with 5-on-4.5-inch pattern
- 3.19-inch center bore and 24.4-inch overall diameter
- The 1,360-pound maximum load per tire is below the 1,820-pound rating of the eCustomRim 15-inch pair.
Skip it if you need a 4-lug hub pattern; the eCustomRim 4.80-12 two-pack specifies four lugs on 4 inches.
For a trailer needing two 13-inch wheels with five-lug, 4.5-inch hubs, this pre-mounted pair simplifies the tire-change workflow. Its 1,360-pound-per-tire limit and 24.4-inch diameter remain essential fit and capacity checks.

5. eCustomRim 4.80-12 Assembly
- Weight: 36 lb
- Material: Steel
- Compatible with Vehicle Type: Trailer
- Wheel Size: 12 in
Best for: Pair for four-lug small trailers.
Why it ranks #5: The two assembled 4.80-12 tires each support 990 pounds and use a 4-lug-on-4-inch pattern, fitting compatible smaller utility or cargo trailers.
Two assembled 4.80-12 tire-and-wheel units make this eCustomRim set a practical spare choice when a small utility or cargo trailer needs a matching pair. Each Load Range C bias-ply tire is rated for up to 990 pounds, and the 4-on-4-inch pattern specifies the intended wheel fit.
The 12-by-4-inch steel rims use a 4-lug, 4-inch bolt pattern and a 2.83-inch center bore, giving buyers several concrete measurements to compare with their trailer hubs. Each tire measures 20.5 inches overall and has a 990-pound maximum load rating at up to 90 PSI. Since the DOT-approved tires, wheels, and valve stems arrive assembled, the pair avoids separate tire mounting; confirm the trailer uses compatible 4-lug wheels.
- Two pre-assembled tire, wheel, and valve-stem units
- DOT-approved assemblies
- 4.80-12 bias-ply tires rated up to 990 pounds each
- 12-by-4-inch steel rims with 4-on-4-inch bolt pattern

Skip it if you have 5-lug hubs; the Garvee 4.80-12 pair uses a 5-on-4.5-inch pattern instead.
Choose this pair for a compatible utility or cargo trailer with 4-lug, 4-inch hubs that needs assembled 12-inch wheels. Its 990-pound-per-tire rating and 20.5-inch diameter are important boundaries to match to the trailer.

6. Garvee 4.80-12 Tire Set
- Weight: 39.9 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
- Wheel Size: 8 in
Best for: Two 12-inch five-lug spares.
Why it ranks #6: This two-pack offers 990-pound capacity per tire, but its 5-lug-on-4.5-inch pattern and 2.95-inch center bore require exact fitment confirmation.
Garvee supplies two pre-mounted 4.80-12 tires on white 12-by-4-inch rims, each using a 5-on-4.5-inch bolt pattern. That pairing gives owners of compatible cargo, utility, boat, or travel trailers two ready-to-fit assemblies, with each tire rated for up to 990 pounds.
The 2.95-inch center bore and 5-on-4.5-inch pattern provide specific hub measurements to check before installation, while the 20.6-inch overall diameter and 4.8-inch section width help identify the tire’s size. Each tire carries a 990-pound maximum load rating and a 90 PSI maximum pressure; 5 mm tread depth is also specified. With two tires already mounted on alloy-steel rims, buyers receive a matched pair without arranging separate tire mounting.
- Two pre-mounted 4.80-12 trailer tires on white rims
- 5-on-4.5-inch bolt pattern and 2.95-inch center bore
- 990-pound maximum load rating per tire
- 90 PSI maximum pressure and 5 mm tread depth

This pair suits trailer owners seeking two 12-inch assemblies for compatible 5-lug, 4.5-inch hubs. Check the 2.95-inch center bore, 20.6-inch diameter, and 990-pound tire rating against the trailer’s requirements.

View on AmazonAvoid a bolt-pattern and center-bore mismatch
A wheel can have the right tire size and still fail to fit if its bolt pattern or center bore differs from the trailer hub. Among these listings, the 15-inch assemblies use five lugs on a 4.5-inch pattern and a 3.19-inch center bore. The eCustomRim 4.80-12 two-pack instead uses four lugs on a 4-inch pattern with a 2.83-inch center bore.
The Garvee 4.80-12 set also has five lugs on 4.5 inches, but its center bore is 2.95 inches. Do not assume two wheels fit simply because both have five lugs or share a nominal tire size.
Check the trailer’s existing wheel markings and measure or verify the hub dimensions before ordering. A mismatch can prevent the wheel from seating correctly or being secured properly, making it unsuitable as an emergency spare even if the tire itself appears close.
Plan for spare-tire clearance, not just diameter
A spare must have enough room to be stored and mounted, so compare its listed overall diameter with the trailer’s current tire and available clearance. These options range from 20.5 inches for the eCustomRim 4.80-12 to 27.2 inches for the ST205/75D15 assemblies; the 13-inch eCustomRim option measures 24.4 inches. A larger assembly may not fit a tight under-frame carrier or intended storage location, while a smaller tire may not match the trailer’s installed size or rolling requirements.
The listings provide nominal dimensions, but they do not establish your trailer’s actual mounting clearance or carrier capacity. Measure the storage space and check the installed tire’s sidewall before buying.
This is especially useful when choosing between the 12-, 13-, and 15-inch options: size is a compatibility decision, not a preference based on appearance.
How to Choose a Utility Trailer Spare Tire
Match tire size and overall diameter
Look for the tire size already specified for your trailer, then check the listed overall diameter and available storage clearance. The options here span 4.80-12 at about 20.5 to 20.6 inches, ST175/80D13 at 24.4 inches, and ST205/75D15 at 27.2 inches. These figures are not interchangeable just because each product is trailer-specific.
A buyer whose trailer uses 15-inch tires should focus on the 15-inch assemblies; a trailer built for 12-inch tires should consider the smaller choices instead. The 13-inch pair suits a trailer whose installed tire size and wheel fitment match that specification.
Use the sidewall and trailer documentation to confirm the required size, and measure the spare’s storage location before choosing a larger diameter.
Check load capacity and pressure
Choose a spare with a load rating that meets the trailer’s requirements, and observe the tire’s stated maximum pressure. The 15-inch Load Range C options are rated for 1,820 pounds per tire at 50 PSI; the 13-inch pair is rated for 1,360 pounds at 50 PSI. Both 12-inch products list 990 pounds per tire and a maximum pressure of 90 PSI.
These are listed tire limits, not a substitute for checking the trailer’s axle, wheel, and load requirements. Buyers replacing a 15-inch tire should compare like-for-like specifications, while owners of smaller trailers should select a 12- or 13-inch option only if its rating is adequate.
Inflate according to the tire and trailer guidance rather than choosing pressure by size alone.
Choose the right wheel pattern and package format
Verify the lug pattern, center bore, and whether you need one spare or a pair before choosing. The 15-inch assemblies use five lugs on 4.5 inches with a 3.19-inch center bore; the eCustomRim 12-inch pair uses four lugs on 4 inches and a 2.83-inch bore. Garvee’s 12-inch set has five lugs on 4.5 inches and a 2.95-inch bore, while its eCustomRim counterpart uses a different pattern.
The eCustomRim white 15-inch listing explicitly includes one mounted assembly and valve stem, whereas several other listings describe two-packs. A buyer replacing a single spare should favor a clearly stated one-assembly package; someone replacing a matched pair may prefer a two-pack, provided its hub fit and quantity suit the trailer.
Which Utility Trailer Spare Tire Should You Choose?
For a clearly specified single spare on a compatible 15-inch, five-lug trailer, choose the eCustomRim ST205/75D15 White Assembly: it includes one mounted tire, wheel, and valve stem and is rated for 1,820 pounds. The eCustomRim 205/75D15 Silver Assembly offers the same listed tire rating and fitment pattern if silver better suits your setup. Choose the eCustomRim ST205/75D15 Black Assembly when its black wheel is preferred, but verify package quantity because its listing also mentions two assemblies.
For a trailer specified for 13-inch wheels, the eCustomRim ST175/80D13 Assembly provides two tires rated at 1,360 pounds each. Smaller-trailer owners should compare the two 4.80-12 sets against their hub: the four-lug eCustomRim and five-lug Garvee versions are not interchangeable.
Frequently Asked Questions
How do I verify that a spare wheel’s bolt pattern and center bore match my trailer?
Check your trailer or hub documentation for the bolt pattern and center-bore requirements, then compare them with the spare assembly listing. A matching lug count alone is not enough: the spacing between the lugs must also match. If the listing does not specify the center bore, confirm it with the seller or a qualified trailer shop before ordering.
Should a trailer spare use the same tire size and load rating as the mounted tires?
Use a spare that meets your trailer maker’s tire-size and load requirements, and compare its rating with the mounted tires. The eCustomRim ST205/75D15 white assembly is rated for up to 1,820 pounds at 50 PSI, but that does not establish suitability for every trailer. Check your trailer’s specifications and the tire sidewall before choosing.
How should I store and maintain a trailer spare between trips?
Keep the spare secured, protected from avoidable damage and exposure, and accessible when needed. Check its pressure and condition before trips, following the tire maker’s guidance for inflation and inspection. Look for visible damage or deterioration, and make sure the wheel is firmly mounted to its carrier.
Replace a spare that is damaged or no longer serviceable.
How can I tell whether an assembly includes one spare or a pair?
Read the product title and listing details for the stated package quantity, and confirm what is included before ordering. Some options are described as two-packs, while the black 15-inch listing also mentions two assemblies. Do not assume the quantity from the product image alone; check the listing’s item details if the quantity is unclear.
Can I use a four-lug spare on a five-lug trailer if the tire size matches?
No. Matching tire size does not make different wheel bolt patterns interchangeable. The four-lug eCustomRim 4.80-12 set and five-lug Garvee 4.80-12 set are intended for different hub patterns, so compare the spare’s pattern with your trailer’s hub before purchase.
Also verify center bore and clearance to confirm fit.
Final Words
For a compatible 15-inch, five-lug trailer, the eCustomRim ST205/75D15 White Assembly is the clearest single-spare choice: it includes a mounted tire, wheel, and valve stem, with a listed 1,820-pound rating. The silver version has the same listed rating and fitment pattern; choose black only after confirming package quantity. For 13-inch or 12-inch setups, match the listed size and lug pattern to your hub, and verify center bore and clearance before ordering.
