Why it ranks #1: Its 205/75R15 radial, 1,820-pound maximum load, 50 PSI rating, and specified 5-on-4.5-inch bolt pattern make fitment checks straightforward.

Radial construction is the defining feature of this eCustomRim assembly, which combines an ST205/75R15 tire with a black 15-inch wheel. Its 1,820-pound maximum load and 5-lug, 5×4.5-inch bolt pattern give trailer owners practical specifications for comparing capacity and mounting compatibility.

A listed 1,820-pound load capacity provides a concrete figure for matching the spare to trailer needs.

#4 · Highest Listed Capacity

4. Free Country 14-Inch Assembly

• Size: ST205/75R14
• Rim Size: 14 in

Best for: Higher-capacity 14-inch spare.

Why it ranks #4: Its 205/75R14 radial size and listed 2,040-pound load capacity stand out, provided the smaller 14-inch rim matches the trailer.

A listed 2,040-pound load capacity sets this Free Country assembly apart among these 14-inch choices, while its ST205/75R14 tire and silver modular wheel form a complete trailer replacement. The 8-ply, Load Range D specification gives buyers a clear point of comparison when selecting a spare.

The ST205/75R14 size identifies a radial tire in a 14-inch wheel format, making it a fit to consider when replacing the same size. Its 8-ply, Load Range D rating and stated 2,040-pound capacity give buyers concrete figures to weigh against trailer requirements. The silver modular rim is included as part of the wheel-and-tire assembly, rather than requiring a separate wheel purchase. The 5×4.5-inch pattern is specified in the title for checking hub compatibility.

• Rim Size: 15 in
• Compatible with Vehicle Type: Trailer

Best for: Silver 8-ply 15-inch spare.

Why it ranks #5: The 205/75R15 assembly lists 8PR, Load Range D, and a 5×4.5-inch PCD, offering a higher-ply option for compatible trailers.

The ROCKMAN assembly pairs an ST205/75R15 tire labeled 8PR D 107M with a silver 15-inch alloy-steel rim, offering a specific higher-ply configuration for trailer owners to assess. Its 5×4.5-inch pattern supplies a concrete mounting detail for checking compatibility with a spare-wheel position.

The ST205/75R15 size and 15-inch wheel designation identify the assembly’s format, while the 5×4.5-inch PCD gives buyers a precise pattern to compare with their trailer hub. Its 8PR, Load Range D marking distinguishes the tire configuration from lower-ply alternatives. The silver rim is specified as alloy steel, so the material and finish are clear when selecting a replacement wheel. The supplied specifications do not provide a load capacity figure, so buyers cannot compare that number from this listing alone.

Skip it if you require a stated load capacity to compare; the Free Country ST205/75R14 lists 2,040 pounds.

This ROCKMAN wheel suits trailer owners seeking an ST205/75R15 8PR D assembly with a silver alloy-steel rim. Match its 5×4.5-inch pattern to the hub, and obtain a load figure separately if that number is central to your choice.

Best for: Black 8PR trailer wheel.

Why it ranks #6: It shares the 205/75R15, 8PR, Load Range D, and 5×4.5-inch PCD specifications of the silver option, with a black mod rim.

The ROCKMAN assembly combines an ST205/75R15 tire marked 8PR D 107M with a black 15-inch modular rim, a defined configuration for trailer owners replacing a wheel. Its 5×4.5-inch pattern provides a specific hub measurement to check before installation.

The ST205/75R15 size identifies the tire format, and the 15-inch rim specification helps buyers compare it with the wheel currently fitted to the trailer. The 8PR, Load Range D marking distinguishes its tire construction, while the 5×4.5-inch PCD provides a concrete bolt-pattern check. ROCKMAN lists the rim material as alloy steel and the finish as black, giving buyers clear material and appearance details. The supplied specifications do not state a load capacity figure for comparison.

Skip it if you need a stated capacity figure; the Free Country ST205/75R14 lists a 2,040-pound load capacity.

Choose this ROCKMAN assembly if a black 15-inch modular rim, ST205/75R15 size, and 8PR D marking suit your trailer. Verify the 5×4.5-inch pattern against the hub, and obtain load information separately if required.

7. Free Country White Rim Assembly

• Size: ST205/75D15
• Rim Size: 15 in

Best for: White-rim 15-inch spare.

Why it ranks #7: This 205/75D15 bias assembly lists a 1,820-pound capacity and 5×4.5-inch fitment, with a white rim for buyers matching that finish.

A white rim differentiates this Free Country ST205/75D15 assembly, which pairs a 6-ply, Load Range C tire with a 15-inch wheel. The listed 1,820-pound capacity and 5×4.5-inch pattern give trailer owners practical figures for comparing the tire and mounting arrangement.

The ST205/75D15 size and 15-inch rim specification identify the assembly’s format, while the 5×4.5-inch pattern in the title gives buyers a direct hub-fitment check.

Its white rim provides a clear finish choice for a replacement wheel. Check the trailer’s required tire construction and dimensions before purchase.

Skip it if you need an 8-ply Load Range D tire; the Free Country ST205/75R14 assembly specifies that construction and a 2,040-pound capacity.

#8

8. TrailQuest Radial Assembly

• Size: 1 Pack
• Rim Size: 15 in
• Compatible with Vehicle Type: Trailer

Best for: Silver modular 15-inch spare.

Why it ranks #8: The 205/75R15 radial on a 5×4.5-inch, five-lug silver rim matches a common listed fitment, but the supplied data gives no load rating.

The TrailQuest assembly combines an ST205/75R15 radial tire with a silver modular 15-inch rim, providing a complete trailer wheel in a 5-lug, 5×4.5-inch pattern. That size and mounting layout give buyers specific details to compare with their trailer before choosing a replacement spare.

The ST205/75R15 designation identifies the tire size and radial construction, while the 15-inch rim specification tells buyers which wheel diameter to compare with their current setup. Its 5-lug, 5×4.5-inch bolt pattern supplies a direct hub-fitment check, and the silver modular rim offers a defined wheel style as part of the assembly. The listing identifies the vehicle type as trailer. It does not provide a load capacity figure, so capacity matching requires information beyond the supplied specifications.

Skip it if you need a listed load figure for capacity comparison; the Free Country ST205/75R14 lists a 2,040-pound capacity.

Consider this TrailQuest assembly if your trailer calls for an ST205/75R15 tire, a 15-inch wheel, and a 5×4.5-inch bolt pattern. Its listing identifies the configuration, but buyers needing a stated load capacity should seek that figure before choosing.

#9 · Best Two-Piece Set

9. Garvee 13-Inch Assembly

• Size: ST175/80D13
• Rim Size: 13 in
• Compatible with Vehicle Type: Trailer

Best for: Two-piece 13-inch replacement set.

Why it ranks #9: This two-piece ST175/80D13 package lists 1,360 pounds maximum load per tire, but its smaller size and two-wheel format suit fewer spare-only needs.

A two-pack of complete tire-and-rim assemblies makes the Garvee set useful when replacing both trailer wheels at once, rather than sourcing a single spare. Each ST175/80D13 tire is listed for a maximum 1,360-pound load, and the 13-inch wheels use a 5-lug, 5×4.5-inch pattern.

The package includes two ST175/80D13 assemblies, giving buyers matching tire-and-wheel replacements for both sides of a trailer. Each tire has a listed 1,360-pound maximum load and 50 PSI maximum pressure, useful figures for comparing requirements and inflation guidance. The 13×5-inch white wheels have a 5-lug, 4.5-inch bolt pattern for fit checks. DOT approval and variable-pitch tread are also specified, with the latter described as reducing road noise during towing.

Skip it if you need a 15-inch replacement; the eCustomRim ST205/75R15 radial assembly uses a 15-inch wheel.

Pick the Garvee set when replacing two trailer wheels in the ST175/80D13 size and its stated load and bolt pattern suit the application. The two-piece package is the key distinction; it is not a 15-inch tire option.
