#1 · Best Overall

1. eCustomRim Radial 205/75R15 Assembly

• Weight: 39 lb
• Wheel Size: 15 in
• Rim Size: 15 in

Best for: 15-inch radial replacement.

Why it ranks #1: The radial ST205/75R15 tire is rated for 1,820 pounds and comes on a 15-inch wheel with a 5-lug on 4.5-inch pattern.

Radial construction is the defining feature of this pre-mounted eCustomRim assembly, giving trailer owners a radial spare in a 205/75R15 size. The black 15-inch wheel uses a 5-on-4.5-inch bolt pattern, and the tire carries a stated 1,820-pound maximum load rating for assessing replacement suitability.

The radial ST205/75R15 tire is rated Load Range C, 1,820 pounds maximum, and 50 PSI, giving buyers explicit load and inflation figures for their spare planning. Its 15-by-5-inch rim, 3.19-inch center bore, and 5-on-4.5-inch pattern provide concrete wheel dimensions to compare with the trailer’s existing setup. At 26.9 inches overall diameter, it differs in stated diameter from the 27.2-inch bias-ply counterpart, so dimensions matter when choosing a replacement.

Skip it if you need a pre-mounted bias-ply spare; the eCustomRim ST205/75D15 assembly offers bias construction and a 27.2-inch diameter.

This suits trailer owners who want a radial 15-inch assembly with explicit load and wheel dimensions. Treat the stated 1,820-pound rating as a per-tire maximum and compare the bolt pattern, bore, and diameter with the trailer’s requirements.

#2 · Best Bias-Ply Option

2. eCustomRim Black 205/75D15 Assembly

• Weight: 36 lb
• Wheel Size: 15 in
• Rim Size: 15 in

Best for: Black 15-inch bias spare.

Why it ranks #2: This ready-to-install bias-ply assembly supports 1,820 pounds and pairs a 15-inch tire with a 5-lug on 4.5-inch wheel.

A black wheel distinguishes this single pre-mounted ST205/75D15 bias-ply assembly, offering trailer owners a ready-to-install 15-inch spare. The tire’s 1,820-pound maximum load rating and the wheel’s 5-lug-on-4.5-inch pattern provide concrete capacity and compatibility details for evaluating a replacement.

The 15-by-5-inch alloy-steel rim, 3.19-inch center bore, and 5-on-4.5-inch bolt pattern give useful dimensions to compare with the trailer’s wheel setup. The 27.2-inch overall diameter helps with tire-size and clearance checks, while Load Range C, 50 PSI, and a 1,820-pound maximum load state the tire’s operating limits. Because the assembly includes a pre-mounted tire, wheel, and valve stem, installation does not require mounting the tire onto a separate rim.

Skip it if you need radial construction in this size; the eCustomRim ST205/75R15 assembly is radial and lists the same 1,820-pound maximum load.

This is a good match for an owner seeking one black, pre-mounted 15-inch bias-ply spare. Check the 5-on-4.5-inch pattern, center bore, tire diameter, and 1,820-pound limit against the trailer before installation.

3. eCustomRim White 205/75D15 Assembly

• Weight: 36 lb
• Wheel Size: 15 in
• Rim Size: 15 in

Best for: 15-inch bias-ply spare.

Why it ranks #3: It offers the same 1,820-pound rating and 5-lug on 4.5-inch pattern as the black 15-inch bias-ply assembly, in a white wheel.

A pre-mounted ST205/75D15 bias-ply tire and white wheel arrive together, giving utility-trailer owners a ready-to-install spare assembly rather than a tire that needs mounting. Its 1,820-pound maximum load rating and 5-on-4.5-inch bolt pattern make the key capacity and wheel-fit details clear for evaluating a replacement.

The 15-by-5-inch wheel, 3.19-inch center bore, and 5-on-4.5-inch bolt pattern help you compare the assembly with a trailer’s existing wheel before installation. The 27.2-inch overall diameter and Load Range C tire provide specific size and load information for a replacement decision, while the pre-mounted tire, wheel, and valve stem simplify the changeover workflow. Its 1,820-pound maximum load and 50-PSI rating are the stated operating limits to consider.

Skip it if you need a radial construction; the eCustomRim ST205/75R15 assembly is a radial option with the same stated 1,820-pound maximum load.

For a trailer owner seeking one pre-mounted 15-inch bias-ply spare, this assembly combines the tire and wheel for a simpler replacement. Check that the 5-on-4.5-inch pattern, center bore, dimensions, and load rating suit the trailer.

#4 · 8-Ply Option

4. ROCKMAN ST205/75R15 Wheel Assembly

• Wheel Size: 15 in
• Rim Size: 15 in

Best for: Silver 15-inch D-rated wheel.

Why it ranks #4: Its ST205/75R15 tire is listed as 8PR and the silver wheel uses a 5×4.5-inch PCD, though a load rating is not supplied.

An 8-ply, Load Range D ST205/75R15 tire paired with a silver mod rim gives this ROCKMAN assembly its defining combination. The title also specifies a 5-by-4.5-inch PCD, making the bolt pattern a useful first check for utility-trailer owners considering a 15-inch radial spare.

The ST205/75R15 size identifies the tire format, while the 8PR and Load Range D markings distinguish its stated construction and load range. Its 5-by-4.5-inch PCD gives a concrete wheel-pattern measurement to compare against the trailer’s hub before selecting it. The silver mod rim completes the assembly, but the supplied specifications do not state a load capacity, inflation pressure, or overall diameter, so those operating details are not established here.

Skip it if you need a stated load capacity and pressure for selection; the eCustomRim ST205/75R15 assembly lists both figures.

Choose this ROCKMAN assembly if its 15-inch radial size, D-range designation, and silver mod rim suit the trailer. Its stated pattern is 5-by-4.5 inches; obtain verified load, pressure, and diameter details before relying on those limits.

#5 · Best 13-Inch Option

5. eCustomRim ST175/80D13 Assembly

• Weight: 54 lb
• Wheel Size: 13 in
• Rim Size: 13 in

Best for: 13-inch five-lug pair.

Why it ranks #5: The two pre-mounted 13-inch assemblies each support 1,360 pounds and use a 5-lug on 4.5-inch pattern.

Two pre-mounted ST175/80D13 bias-ply assemblies make this eCustomRim pack a practical spare-and-replacement option for trailers using 13-inch, five-lug wheels. Each Load Range C tire is rated for 1,360 pounds at 50 PSI, and the 5-on-4.5-inch bolt pattern gives a concrete compatibility check.

The 13-by-4.5-inch rims have a 3.19-inch center bore and 5-lug-on-4.5-inch pattern, letting buyers compare the wheel dimensions with the trailer before fitting. At 24.4 inches overall diameter, the ST175/80D13 tire offers another key measurement for checking clearance. Both assemblies arrive pre-mounted with valve stems, reducing the installation steps compared with sourcing tires and wheels separately; each tire’s stated maximum load is 1,360 pounds at 50 PSI.

Skip it if you need a 15-inch tire rated to 1,820 pounds; the eCustomRim ST205/75D15 assembly lists that higher per-tire capacity.

This pair suits owners of compatible utility or recreational trailers needing 13-inch, five-lug assemblies. Compare its 5-on-4.5-inch pattern, 24.4-inch diameter, and 1,360-pound tire rating with the trailer’s requirements.

#6 · Best 4-Lug Option

6. eCustomRim 4.80-12 4-Lug Assembly

• Weight: 36 lb
• Wheel Size: 12 in
• Rim Size: 12 in

Best for: Ready-to-fit 12-inch pair.

Why it ranks #6: This two-pack includes mounted 4.80-12 tires rated at 990 pounds each, with 12-inch wheels and a 4-lug on 4-inch pattern.

Two pre-mounted 4.80-12 bias-ply assemblies arrive with DOT-approved tires, steel wheels, and valve stems, giving trailer owners a paired replacement ready for installation. Each tire is rated for 990 pounds at up to 90 PSI, and the white 4-lug wheel pattern targets compatible utility and cargo trailers.

Each 12-by-4-inch rim has a 2.83-inch center bore and 4-lug-on-4-inch bolt pattern, giving buyers concrete measurements to compare with the trailer hub. The 20.5-inch overall diameter and Load Range C tire help assess size and stated load characteristics. Since the pair arrives assembled with valve stems, the workflow avoids mounting tires onto separate wheels; the stated 990-pound maximum per tire and 90-PSI limit remain important operating boundaries.

Skip it if you need a 5-lug wheel; the eCustomRim 4.80-12 assembly with a 5-on-4.5-inch pattern is an alternative.

For a trailer owner replacing two compatible 4.80-12 wheels, this assembled pair offers a clear capacity and fitment specification set. Verify the 4-lug pattern, center bore, diameter, and 990-pound tire limit for the intended trailer.

7. eCustomRim 4.80-12 5-Lug Assembly

• Weight: 36 lb
• Wheel Size: 12 in
• Rim Size: 12 in

Best for: Five-lug 12-inch pair.

Why it ranks #7: Its two 4.80-12 assemblies are rated for 990 pounds each and use 5-lug on 4.5-inch wheels, but the listed maximum pressure is 60 PSI.

Two 4.80-12 bias-ply assemblies with 5-lug wheels give owners of compatible utility, boat, and equipment trailers a paired replacement option. The 5-on-4.5-inch pattern sets this listing apart from four-lug 12-inch assemblies, while each tire carries a stated 990-pound maximum load rating.

Each 12-by-4-inch wheel uses a 5-on-4.5-inch bolt pattern and 2.95-inch center bore, allowing a buyer to check those dimensions against the trailer’s hub. The 20.5-inch overall diameter helps with size comparison, and Load Range C specifies the tire’s range. These assemblies are rated for 990 pounds per tire and a maximum 60 PSI; compared with 4.80-12 tires rated for 90 PSI, the lower stated pressure is an important operating distinction.

Skip it if you need a 4.80-12 tire rated to 90 PSI; the eCustomRim 4.80-12 four-lug pair lists that pressure limit.

Choose this pair if the trailer uses 4.80-12 tires and a 5-on-4.5-inch wheel pattern. Its 990-pound per-tire rating and 60-PSI maximum are central boundaries, alongside the 2.95-inch center bore.

#8

8. Garvee 4.80-12 Tire-and-Wheel Set

• Weight: 39.7 lb
• Rim Size: 12 in

Best for: Two 12-inch trailer assemblies.

Why it ranks #8: The two 4.80-12 tires are rated for 990 pounds at 90 PSI and arrive on 12-inch wheels with a 4-lug on 4-inch pattern.

Two preassembled 4.80-12 tires and black 12-inch steel rims make this Garvee pack useful when a trailer owner needs a matched pair rather than a single spare. The 4-lug-on-4-inch pattern and Load Range C rating provide specific fit and capacity details for assessing compatible utility, boat, or cargo trailers.

Each 6-ply tire is rated to 990 pounds at 90 PSI, giving buyers stated load and inflation limits for planning a replacement pair. The included 12-by-4-inch black steel rims use a 4-lug-on-4-inch bolt pattern, so the wheel arrangement can be checked against the trailer before fitting. Having two tire-and-rim assemblies together supports replacing both sides, though the 4.80-12 size and pattern narrow compatibility to trailers using those dimensions.

Skip it if you need a 15-inch spare; the eCustomRim ST205/75D15 assembly offers that larger tire size and a 5-lug pattern.

This pair fits buyers replacing two matching 4.80-12 assemblies on a compatible utility, boat, or cargo trailer. Check the 4-lug-on-4-inch pattern and each tire’s 990-pound rating against the trailer before use.

9. GarveeTech 4.80-8 Tire-and-Wheel Set

• Wheel Size: 42.2 centimeters
• Rim Size: 25 in

Best for: Compact 8-inch wheel pair.

Why it ranks #9: This two-pack suits smaller trailers with 8-inch wheels; each 4.80-8 tire is rated for 760 pounds and uses a 4-lug pattern.

A two-pack of 4.80-8 tires on 8-inch wheels gives small utility trailers, compact trailers, and ATV carts a compact replacement option. Each 6PR tire is rated for 760 pounds at up to 90 PSI, while the 4-lug-on-4-inch PCD identifies a key wheel-fit measurement.

The 16.6-inch stated overall diameter and 5-inch section width help buyers compare the tire’s footprint with the trailer’s available clearance and existing size. Its 4-lug-on-4-inch PCD and 8-inch wheel provide specific dimensions to check at the hub. GarveeTech lists a 760-pound capacity and 90-PSI maximum inflation pressure, giving the pair clear operating limits; confirm the center bore and other dimensions against the trailer because the listing calls for those checks.

Skip it if you need a 4.80-12 assembly with a higher stated capacity; the Garvee 4.80-12 pair is rated at 990 pounds per tire.

This pair suits compact trailers or ATV carts using 4.80-8 tires and a 4-lug-on-4-inch pattern. Its 760-pound capacity and 16.6-inch diameter are key boundaries; compare the full wheel dimensions with the trailer.

#10

10. Transeagle TE898 4.8-12 Tire

• Weight: 11 lb
• Rim Size: 12 in

Best for: 12-inch tire-only replacement.

Why it ranks #10: It is a trailer-specific 4.8-12 bias tire rated for 992 pounds, but it is tire-only and does not include the wheel needed for a complete spare.

The Transeagle TE898 is a tire-only 4.8-12 option, making it relevant to trailer owners who need the tire rather than a complete wheel assembly. Its stated 6-ply construction and 992-pound load capacity give buyers concrete replacement specifications, while the all-season, highway-terrain description identifies its intended trailer use.

Because this listing includes the tire only, buyers can focus on a replacement tire while retaining a compatible existing wheel; a rim is not listed as included. The 4.8-12 size and 992-pound load capacity help define the size and load checks for that replacement. Transeagle describes the TE898 as an all-season highway-terrain trailer tire with a reinforced internal structure intended to maintain shape under load and towing pressure; it should not be mounted on light trucks.

Skip it if you need a tire and wheel together; the Garvee 4.80-12 two-pack includes assemblies with 12-inch rims.

This is for a trailer owner replacing a 4.8-12 tire while using a compatible wheel already on hand. Keep its tire-only format and stated 992-pound capacity in view, and do not mount it on a light truck.
