Best Spare Tire Bumper Mounts for RVs and Trailers

#1 · Best Overall

1. Safoner RV Spare Tire Mount

• Weight: 9.2 lb

Best for: Raised RV bumper mounting.

Why it ranks #1: Designed for standard 4-inch-square RV bumpers, it supports specified dimensions up to 4.4 inches high and 4.3 inches wide and has a 22-inch post.

A 22-inch vertical post lifts the spare higher above the bumper, helping reduce scraping on driveways, dips, and uneven roads. Safoner combines that extra clearance with a thick aluminum-alloy carrier and a triple-lock arrangement for buyers mounting a spare on a standard square RV bumper.

The post’s 22-inch height is the central practical benefit: raising the tire can help keep it clear when the trailer crosses uneven approaches. Three one-piece formed aluminum components have no welded joints, while an anti-loosening washer and dual nuts add layers to the mounting arrangement. Fit is specific to standard 4-inch square RV rear bumpers, with stated limits of 4.4 inches high and 4.3 inches wide, so measuring the bumper matters before choosing it.

Skip it if you mount a utility-trailer tire on a tongue; Joroamp’s BYTJ31-5.5G lists multiple lug patterns and tongue dimensions.

This suits RV owners seeking a raised spare-tire position on a standard 4-inch square rear bumper. Check the bumper’s height and width against the stated limits; its tall post is the main clearance consideration.

#2 · Raised Post

2. Tordale Trailer Spare Tire Mount

• Material: Alloy Steel

Best for: Raised 4-inch RV bumper mount.

Why it ranks #2: This alloy-steel RV mount fits 4-inch rear square bumpers and uses a 22-inch raised pillar to lift the spare above the bumper.

A 22-inch raised pillar lifts the spare above the bumper, helping reduce scraping when an RV crosses lanes, potholes, and uneven approaches. Tordale pairs that clearance-focused height with alloy-steel construction and two precision-welded components for owners mounting a spare on a 4-inch rear square bumper.

The raised pillar positions the spare higher than a standard low mount, which can help limit contact with the road on uneven routes. Two precision-welded alloy-steel components form the carrier, and a powder-coated surface is specified for outdoor use. The listing identifies this as an RV rear-bumper mount for 4-inch square bumpers, so it is a focused choice rather than a multi-pattern trailer-tongue bracket.

Skip it if you need a folding carrier for a 15- or 16-inch tire; woiron’s CP0100-00300203 lists folding and those wheel sizes.

Tordale suits RV owners who prioritize a raised spare position on a 4-inch square rear bumper. Its bumper-specific application is the key fit consideration; the 22-inch pillar is the clearance feature to assess.

#3 · Rigid 4-Inch Fit

3. Stromberg Carlson TR-1

• Weight: 8.5 lb
• dimensions: 19 x 10 x 7 in

Best for: Rigid 4-inch bumper carrier.

Why it ranks #3: Its stated fit for 4-inch square bumpers and 15- and 16-inch travel-trailer tires gives buyers a clearly specified rigid option.

Extra-thick welded steel gives the Stromberg Carlson TR-1 a rigid structure for carrying a travel-trailer spare. It fits 15- and 16-inch tires and mounts to a 4-inch square bumper, a focused combination for RV owners who want a fixed rather than folding carrier.

The TR-1’s extra-thick welded-steel construction provides a sturdy carrier structure for travel, while its powder-coated finish is specified for the mount. Compatibility with 15- and 16-inch travel-trailer tires narrows the wheel-size choice, and the 4-inch square bumper requirement helps buyers assess the mounting point. Its rigid format keeps the configuration simple, but it does not offer the folding arrangement listed for some other carriers.

Skip it if you want a folding mount for a 15- or 16-inch spare; woiron’s CP0100-00300203 lists a folding design.

The TR-1 suits owners of 15- or 16-inch travel-trailer tires who need a rigid mount for a 4-inch square bumper. Its fixed format is the relevant boundary if folding access matters to you.

#4 · Folding Design

4. woiron Folding RV Bracket

• Weight: 3.75 kg
• Material: Alloy Steel
• dimensions: 18 x 2.8 x 7 in

Best for: Folding mount for 15- and 16-inch tires.

Why it ranks #4: This folding steel carrier mounts to 4-inch square bumpers, fits 15- and 16-inch travel-trailer tires, and has a listed 150-pound capacity.

Its folding design gives this woiron carrier a space-conscious format for mounting a spare on a 4-inch square bumper. It fits listed 15- and 16-inch travel-trailer tires and has a 150-pound capacity, making those wheel sizes and the folding mechanism its defining considerations for RV owners.

The folding bracket combines a 4-inch square bumper mount with compatibility for 15- and 16-inch travel-trailer tires, giving buyers a clear way to compare it with their existing setup. Alloy-steel construction is specified for the carrier, and the listing states a 150-pound load capacity. The folding format is relevant when storage or access around the mounted spare matters, though the supplied information does not describe a particular folding procedure or folded dimensions.

Skip it if you need a carrier for four-, five-, or six-lug bolt patterns; GADFISH’s GADFISH003 lists those wheel patterns.

Choose this woiron bracket if your travel-trailer spare is 15 or 16 inches and the bumper is a 4-inch square. Its folding format and 150-pound limit are the main boundaries to weigh.

#5 · Adjustable Width

5. Outus Spare Tire Carrier

• Weight: 7.2 lb
• Material: Alloy Steel
• dimensions: 14.17 x 12.6 x 2.76 in

Best for: Adjustable-width bumper mounting.

Why it ranks #5: The alloy-steel carrier is described for a 4-inch square bumper and offers a stated width range of 1.5 to 4 inches.

An adjustable width from 1.5 to 4 inches, with a 3-inch depth, lets this Outus mount accommodate a range of trailer frames. That dimensional flexibility is its key differentiator for buyers with a compatible 4-inch square bumper, while alloy-steel construction supplies the carrier’s specified material.

The adjustable width range of 1.5 to 4 inches and stated 3-inch depth give buyers concrete dimensions to compare with a mounting frame before installation. The title identifies a 4-inch square bumper application, and the alloy-steel construction provides a metal carrier structure. The listing also describes a compact design, which may help conserve mounting space, but no tire-size pattern or load-capacity figure is supplied in the provided product facts.

Skip it if you need a stated load rating before choosing; GADFISH’s GADFISH002 specifies a 150-pound capacity.

Consider Outus when adjustable mounting width is the priority and its stated dimensions suit your bumper setup. The supplied facts do not state a load capacity or tire-size fit, so those are important boundaries.

#6

6. SELEWARE Trailer Spare Tire Carrier

Best for: Triangular support for RV spares.

Why it ranks #6: Its reinforced triangular steel design has a listed 160-pound capacity, though the provided details do not specify bumper dimensions or wheel patterns.

A reinforced triangular support and rectangular backplate give this SELEWARE carrier a stable steel structure with a stated 160-pound capacity. It is listed for 15- and 16-inch wheels, making it a focused option for travel-trailer owners seeking reinforced support for those spare sizes.

The solid-steel carrier uses reinforced laser welding, a triangular support structure, and a rectangular backplate to keep the spare supported on the trailer. Its 160-pound rating supplies a clear load limit, while the listed 15- and 16-inch wheel fit helps narrow compatibility. A setup video is also noted in the supplied facts, offering visual guidance for assembly without changing the need to match the carrier to the trailer and spare.

Skip it if you need a carrier rated for a 300-pound load; toolhoper’s BTZJ lists that higher capacity.

This SELEWARE carrier suits owners of 15- or 16-inch trailer spares who value welded triangular support and a 160-pound rating. Check that the spare falls within the listed wheel sizes and load limit.

#7

7. GADFISH Elevated Folding Mount

• Weight: 8 lb
• Material: Metal
• dimensions: 2 x 2 x 17 in

Best for: Elevated folding trailer carrier.

Why it ranks #7: The 17-inch elevated folding design supports up to 150 pounds and fits several 4-, 5-, and 6-lug bolt patterns, but bumper dimensions are not stated.

A 17-inch elevated, folding design raises the spare while adding a foldable format to this GADFISH carrier. Its triangular welded reinforcement supports a stated 150-pound load, and compatibility spans specified four-, five-, and six-lug trailer wheel patterns for buyers seeking height and broad pattern coverage.

The 17-inch elevation is intended to reduce the chance of the mount being scratched, while the folding design offers a different format from a rigid carrier. A triangular welded structure and rectangular back plate secure the steel beam, supporting the stated 150-pound capacity. The listed wheel patterns cover four-lug 4-inch, five-lug 4.5-, 4.75-, and 5-inch, and six-lug 5.5-inch layouts, helping buyers match the mount to their trailer wheel.

Skip it if you need a carrier rated above 150 pounds; toolhoper’s BTZJ lists a 300-pound capacity.

This GADFISH model fits trailer owners who want an elevated folding carrier and whose wheel matches its listed patterns. The 150-pound rating is a clear boundary, so check the spare’s load against it.

#8

8. toolhoper RV Spare Tire Carrier

• Weight: 13.66 lb

Best for: High-capacity multi-lug RV carrier.

Why it ranks #8: Its welded triangular steel frame has a stated 300-pound capacity and fits 4-, 5-, 6-, and 8-lug wheels, but bumper fit details are absent.

A 300-pound capacity paired with a triangular welded steel frame gives this toolhoper carrier a substantial load rating and a rigid support structure. Its three-nut design also targets a quieter, tighter fit, making it relevant to RV owners whose spare wheel uses one of the listed four-, five-, six-, or eight-lug patterns.

The 14-pound steel frame uses triangular welded construction, which the listing says provides high torsional rigidity; that structure is intended to resist bending and keep the spare firmly supported. A three-nut arrangement aims to reduce movement, vibration, and clanging during travel. Compatibility spans four-, five-, six-, and eight-lug wheels, while the 300-pound stated capacity gives buyers a clear rating to compare with their spare tire and mounting setup.

Skip it if you want a lighter carrier; GADFISH’s GADFISH002 is listed at 2.67 kilograms and supports up to 150 pounds.

Consider this carrier when a high stated load rating and broad lug-count compatibility matter for your RV spare. Its steel frame weighs about 14 pounds, so account for that weight in your mounting setup.

#9

9. GADFISH Spare Tire Carrier

• Weight: 2.67 kg
• Material: Iron
• dimensions: 8.66 x 5.91 x 5.91 in

Best for: Boat trailer multi-pattern fit.

Why it ranks #9: This triangular iron trailer carrier holds up to 150 pounds and fits listed 4-, 5-, and 6-lug patterns, but no RV bumper fit is specified.

A triangular welded structure and rectangular backing plate support this GADFISH carrier’s 150-pound load rating. Its listed fit covers four-, five-, and six-lug trailer wheels across several bolt patterns, giving boat and utility trailer owners a way to match the bracket to more than one common wheel layout.

The reinforced triangular structure is paired with a rectangular plate that holds the steel beam firmly, providing the support behind its stated 150-pound capacity. Listed patterns include four-lug 4-inch holes, five-lug 4.5-, 4.75-, and 5-inch holes, and six-lug 5.5-inch holes. That range helps buyers check their existing wheel pattern against the carrier before mounting, while the iron construction provides the bracket’s rigid metal structure for trailer use.

Skip it if you need a raised or folding carrier; GADFISH’s GADFISH003 lists an elevated 17-inch folding design.

This is a straightforward option for boat or utility trailer owners whose wheel matches one of the specified bolt patterns. Keep the 150-pound capacity in mind when deciding whether its load rating suits your spare.

#10

10. Joroamp Utility Trailer Mount

• Weight: 8.8 lb
• Material: Metal
• dimensions: 17.8 x 8 x 7.5 in

Best for: Multi-lug utility trailer owners.

Why it ranks #10: It has a three-nut design, 180-pound capacity, and broad lug-pattern compatibility, but its tongue-mounted utility-trailer fit does not match a bumper-mount search.

Its upgraded three-nut arrangement is intended to lock the spare more securely, reducing vibration and road noise while you travel. Joroamp pairs that retention approach with compatibility across listed four-, five-, and six-lug wheel patterns, making it a flexible option for utility trailer setups.

The mount supports four-lug patterns with 4-inch holes, five-lug patterns with 4.5-, 4.75-, or 5-inch holes, and six-lug patterns with 4.5-, 5.32-, or 5.5-inch holes. That range can accommodate several common trailer wheel layouts without restricting the choice to one lug count. Its 180-pound capacity gives a clear load boundary, while the tongue-fit dimensions—up to 4 inches wide and 5 inches high—help you check the mounting point before installation.

Skip it if you need a rear-bumper carrier that raises the spare; Safoner’s Aluminum RV Spare Tire Mount has a 22-inch vertical post.

Choose this Joroamp for a utility trailer when your wheel matches one of its listed lug patterns and the tongue stays within the stated dimensions. Its 180-pound limit is the key load boundary to consider.
