A strong roof-rack spare tire mount should match your tire diameter and rack style, then hold the wheel securely without obstructing your setup. The RANSOTO Universal Steel Roof Rack Carrier is a strong general-purpose starting point: it supports tires up to 35 inches and includes a locking setup with a J-hook, top plate and base plate. This roundup also includes adjustable-slot hardware, crossbar-specific mounts, basket and platform options, and established designs for named rack systems.
Those differences matter because a carrier made for a basket floor may not attach to crossbars or a T-slot platform. Check your rack and wheel dimensions before choosing, and compare how each mount secures the tire.
The listed products cover tires up to 35 inches in several cases, while some have narrower or less clearly specified fitment.
The RANSOTO Universal Steel Roof Rack Carrier is the best overall choice in this group for a general roof-rack setup. It fits spare tires up to 35 inches and uses a base plate, J-hook and top plate, with a wing nut and padlock for locking. Its four rubber clamps secure the base plate under the rack.
Confirm that your rack can accommodate this mounting arrangement and that your tire stays within the stated size and load limits before buying.

Detailed Reviews: Best Spare Tire Mount For Roof Rack

#1 · Best Overall
1. RANSOTO Universal Steel Carrier
- Material: Alloy Steel
- Weight: 2.8 kg
- Compatible with Vehicle Type: Car
Best for: 35-Inch Tire Roof-Rack Carrier.
Why it ranks #1: Fits tires up to 35 inches and includes four rubber clamps, a J-hook, top plate, wing nut and padlock for a defined mounting and locking arrangement.
A four-clamp base plate secures beneath the roof rack, giving the RANSOTO a defined mounting setup for spare tires up to 35 inches. Its J-hook passes through the wheel rim and top plate, while a wing nut and padlock lock the assembly together, moving the spare out of the vehicle’s interior.
The alloy-steel mount has a black-painted, rust-resistant finish, which suits a carrier exposed to outdoor conditions. Installation uses the supplied instructions and accessories: four rubber clamps fix the base plate under the rack, and the J-hook connects the base plate, rim, and top plate. Tightening the wing nut and adding the included lock provide a clear securing sequence. The listed load capacity is 35 pounds, so check that limit alongside the 35-inch tire-size maximum when choosing a spare.
- Fits spare tires up to 35 inches
- Base plate fixes under the rack with four rubber clamps
- J-hook and wing nut secure the wheel through the rim
- Includes mounting accessories and a lock
- The listed load capacity is 35 pounds, a limit to check for heavier spares.
Skip it if you need a listed load capacity above 35 pounds; this carrier is specified for 35 pounds.
Choose the RANSOTO if you want a lockable, under-rack carrier for a spare up to 35 inches and value its clamp-and-J-hook installation. Its listed 35-pound load capacity is a key boundary, so account for the wheel’s weight before buying.

#2 · Most Adjustable
2. YSKMZKK Adjustable Roof Carrier
- Material: Carbon Steel
- dimensions: 12 x 6 x 4 in
- Compatible with Vehicle Type: Car
Best for: Adjustable-Mounting Roof-Rack Carrier.
Why it ranks #2: Eight elongated slots on its 12 × 4.7-inch base allow horizontal and vertical adjustment, and the listing includes a lock and one-year manufacturer warranty.
Eight elongated slots across a 12-by-4.7-inch base let the YSKMZKK carrier adjust horizontally and vertically, helping position it on different roof racks and cargo baskets. It is specified for spare tires up to 35 inches, with an adjustable layout rather than a fixed-hole mounting plate.
The eight slots give installers a choice of mounting positions, which can help align the carrier with a rack or basket’s available mounting points. The carbon-steel carrier measures 12 by 6 by 4 inches overall, while its base is listed as 12 by 4.7 inches; measuring the rack before ordering is specifically advised. The product description also identifies matched wedge-lock washer pairs as part of its vibration-resistant fastening approach. A lock is included, and the title sets the tire limit at 35 inches.
- Eight elongated slots allow horizontal and vertical adjustment
- 12-by-4.7-inch base offers multiple mounting positions
- Carbon-steel construction
- Includes a lock
- The listed maximum tire diameter is 35 inches.
Skip it if you need a carrier specified for a tire larger than 35 inches; this YSKMZKK model is listed up to 35 inches.
Pick this YSKMZKK for a roof rack or basket where mounting position flexibility matters, especially if fixed holes are inconvenient. Measure the rack first, as advised, and keep the stated 35-inch tire maximum in view.

#3 · Best Rack Versatility
3. maXpeedingrods Universal Carrier
- dimensions: 15.83 x 6.38 x 4.37 in
- Weight: 3000 g
- Compatible with Vehicle Type: SUV, Truck, Jeep and Cars
Best for: Basket and T-Slot Rack Fit.
Why it ranks #3: Supports tires up to 35 inches and describes installation on both roof cargo baskets and platform-style racks with T-slots.
Two distinct installation methods make the maXpeedingrods carrier useful across roof cargo baskets and platform-style racks: loops and clamps for baskets, or T-nuts for T-slots. It holds spare tires up to 35 inches, pairing that stated limit with a high-strength steel bracket.
For a cargo basket, the base plate attaches underneath and connects to the base plate’s loops with J-hooks, then two clamps tighten with bolts and nuts. That sequence gives basket owners a described mounting path. On a platform rack, T-nuts screw into the T-slot instead, so the installation method follows the rack type. The steel bracket has a powder-coated surface intended to resist wear and impact. Its listed dimensions are 15.83 by 6.38 by 4.37 inches; allow for that footprint when arranging other rack cargo.
- Fits spare tires up to 35 inches
- Lists separate installation methods for baskets and platform T-slots
- Basket setup uses a base plate, J-hooks, and two clamps
- High-strength steel has a powder-coated surface
- The listed 15.83-inch length may constrain placement alongside other rack cargo.
Skip it if you lack a cargo basket or platform rack with T-slots; its specified installation methods use one of those rack arrangements.
This carrier is a practical match for owners choosing between a roof basket and a T-slot platform, with installation steps specified for both. Check the 15.83-inch length against available rack space and keep the 35-inch tire limit in mind.

#4 · Best Crossbar Fit
4. Sidasu Heavy Duty Mount
- Material: Carbon Steel
Best for: Adjustable Crossbar Tire Mount.
Why it ranks #4: Fits tires up to 35 inches and is specified for crossbars from 1 to 3 inches thick, with rubber isolators in its vibration-reduction structure.
Adjustable brackets accommodate roof-rack crossbars from 1 to 3 inches thick, giving this Sidasu carrier a defined fit range across many SUV, truck, and off-road racks. It supports spare tires up to 35 inches and uses a dual-layer stabilization design with rubber isolators.
The 1-to-3-inch crossbar thickness range gives buyers a concrete measurement to compare with their rack before installation. Adjustable mounting brackets provide flexibility across the listed SUV, truck, and off-road vehicle uses, while the 35-inch tire maximum sets the spare-size boundary. Carbon-steel construction forms the carrier body, and the vibration-reduction structure uses rubber isolators in a dual-layer design. Together, those details make it a roof-mounted storage option for moving a full-size spare out of the cabin, provided the rack dimensions and tire size fall within the stated limits.
- Supports spare tires up to 35 inches
- Adjustable brackets fit crossbars 1 to 3 inches thick
- Compatible with many SUV, truck, and off-road roof racks
- Dual-layer vibration-reduction structure includes rubber isolators
- Crossbars outside the specified 1-to-3-inch thickness range are beyond its listed fit.
Skip it if you have crossbars thinner than 1 inch or thicker than 3 inches; the listed range does not cover them.
This Sidasu is suited to SUV, truck, and off-road owners whose crossbars measure 1 to 3 inches thick and whose spare is no larger than 35 inches. Check both dimensions before choosing this adjustable-bracket setup.

#5 · Best Locking System
5. Sidasu Universal Tire Carrier
- Compatible with Vehicle Type: Truck, SUV, Off-road Vehicles
Best for: Locking Carrier for Rough Routes.
Why it ranks #5: Its listed security system has a magnetic base and two keys, while the reinforced carbon-steel construction is described as having a protective baked-on coating.
A built-in lock with two keys gives the Sidasu a security-focused way to carry a spare tire up to 35 inches on a roof rack. Its dual-layer vibration-control design combines rubber isolators and magnetic stabilizers, aiming to keep the mounted tire steadier during transit.
Reinforced carbon steel and a baked-on protective coating are specified for durability and rust resistance in varied weather, making the carrier a fit for truck, SUV, and off-road use. The integrated locking system is paired with two keys, so securing the spare does not depend on a separately described lock. Rubber isolators and magnetic stabilizers form the dual-layer vibration-control setup, a practical detail for buyers concerned about movement while driving. The title specifies a 35-inch tire limit.
- Supports spare tires up to 35 inches
- Built-in locking system includes two keys
- Dual-layer design combines rubber isolators and magnetic stabilizers
- Carbon steel construction has a baked-on protective coating
- The title limits compatible spare tires to 35 inches.
Skip it if you carry a spare larger than 35 inches; the YSKMZKK SPCX73 is also specified for tires up to 35 inches, so neither listed option fits that size.
This Sidasu suits truck, SUV, and off-road owners seeking a lockable roof-rack carrier with specified vibration-control components. Keep the 35-inch tire limit in mind, and consider whether its locking and stabilizing features match your transit needs.

6. Yakima Spare Tire Carrier
- Material: Possibly Steel or Aluminum Alloy
- dimensions: 5.25 x 2.25 x 14 in
- Weight: 0.27 g
- Compatible with Vehicle Type: Car, SUV
Best for: Yakima Basket Spare Carrier.
Why it ranks #6: Carries tires up to 35 inches on LoadWarrior, MegaWarrior or OffGrid baskets and offers quick release, though its stated load capacity is 11.02 pounds.
Compatibility with Yakima LoadWarrior, MegaWarrior, and OffGrid baskets gives this spare carrier a clearly defined home, freeing interior room while keeping the tire accessible. It carries spares up to 35 inches and uses a quick-release setup for installation and removal.
The named basket compatibility makes this a targeted option rather than a universal rack mount: it is specified for LoadWarrior, MegaWarrior, and OffGrid baskets. The 35-inch tire capacity sets the size limit, while the quick-release feature can simplify taking the carrier off when the spare or rack arrangement changes. Installation is described as taking five minutes with some assembly required. Mounting the spare on the basket can free up space inside the vehicle, although buyers with other basket models should not assume compatibility from this listing.
- Compatible with LoadWarrior, MegaWarrior, and OffGrid baskets
- Carries spare tires up to 35 inches
- Quick-release feature aids installation and removal
- Installation is listed at five minutes with some assembly
- Compatibility is specified for three Yakima basket models, not all roof racks.
Skip it if you use a different basket or a crossbar-only rack; the Front Runner Spare Wheel Clamp/Low Profile mounts across two slats.
This Yakima carrier suits owners of LoadWarrior, MegaWarrior, or OffGrid baskets who want an accessible spare outside the cabin. Confirm your basket is one of those named and keep the 35-inch tire limit in mind.

7. BajaRack Floor Mount
- Material: Metal
- dimensions: 12 x 6 x 4 in
- Weight: 5 lb
- Compatible with Vehicle Type: All Terrain Vehicle
Best for: Lockable Rack-Floor Mount.
Why it ranks #7: This lockable metal mount is designed for the floor of a rack, but the listing excludes mesh flooring and does not state a tire-size limit.
A rack-floor mounting layout with provisions for adding a lock gives the BajaRack carrier a security-minded role for spare-tire storage. Its metal brackets use an epoxy-primer rust barrier beneath black powder coating, while the product description specifies that the mount is not for mesh flooring.
The carrier mounts on the floor of the rack, so its intended position is different from crossbar-mounted designs. The metal brackets include provisions to add a lock, letting buyers secure the accessory with a lock of their choosing. An epoxy primer provides a rust barrier, and the black powder coating adds another stated surface treatment. The listed dimensions are 12 by 6 by 4 inches. Most importantly for installation planning, the supplied description excludes mesh flooring; check the rack floor construction before selecting this mount.
- Mounts on the floor of the rack
- Provides for adding a lock
- Metal brackets use an epoxy-primer rust barrier
- Black powder-coated finish
- The mount is not compatible with mesh flooring.
Skip it if you have a mesh-floor rack; this BajaRack mount is specified for rack floors other than mesh.
Choose the BajaRack if your rack has a suitable solid floor and you want provisions for adding a lock. Its floor-mounted arrangement and stated mesh-floor exclusion are decisive fit considerations before purchase.

8. Generic Crossbar Tire Carrier
- Material: Alloy Steel
- dimensions: 10 x 3 x 8 in
Best for: Crossbar-Mounted Overlanding Spare.
Why it ranks #8: Designed to attach directly to roof-rack crossbars with high-strength bolts and a wing nut, but the listing does not state a maximum tire diameter.
A fixed base attaches directly to roof-rack crossbars with high-strength bolts, giving this manganese-steel carrier a straightforward crossbar-focused setup for tires up to 35 inches. Its wing-nut quick-release design is intended to make removing the spare simpler when access is needed.
The crossbar-specific fixed base is described as fitting various bar sizes, while the bolts provide the stated attachment method. High-strength manganese steel and a rustproof coating address strength and corrosion resistance for outdoor use. Once mounted, the wing nuts provide the quick-release feature, which can make tire removal more direct than an arrangement requiring a separate release step. The listed dimensions are 10 by 3 by 8 inches. Its stated tire-size ceiling is 35 inches, so larger spares fall outside the product’s specified range.
- Fits spare tires up to 35 inches
- Attaches directly to roof-rack crossbars with bolts
- Manganese-steel construction has a rustproof coating
- Wing-nut design provides quick release
- Its stated maximum tire size is 35 inches.
Skip it if you use a platform rack rather than crossbars; the maXpeedingrods carrier lists a separate T-slot installation method for platform-style racks.
Consider this carrier if your setup uses roof-rack crossbars and you want bolt attachment with a wing-nut release. Its stated 35-inch tire limit and crossbar-specific mounting are the key boundaries to check against your spare and rack.

9. Front Runner Low Profile Clamp
- Material: Alloy Steel
- Weight: 3 lb
Best for: Raised-Dish Rim Clamp Mount.
Why it ranks #9: The clamp mounts across two slats and accommodates deep offsets, but it is designed for a raised-dish rim with the hollow side facing up rather than broadly specified tire fit.
A low-profile clamp that mounts across two slats secures the spare with its hub toward the rack, making the Front Runner a specific choice for raised-dish rims. It tightens against the wheel’s back side to protect the finish and accommodates deep offsets.
The clamp is specifically intended for a raised-dish rim with its hollow side facing up, so wheel orientation matters when planning the mount. Spanning two slats gives it a defined rack attachment arrangement, and the clamp tightens against the back of the wheel to protect the visible finish. The listing says it can handle mostly any size wheel and accommodate even the deepest offsets, offering flexibility for varied wheel dimensions. It is an alloy-steel vise-style clamp; verify that the rim profile matches its stated mounting orientation.
- Mounts across two rack slats
- Specified for raised-dish rims with the hollow side facing up
- Tightens against the wheel’s back side to protect its finish
- Accommodates deep offsets
- Its stated orientation is specific to raised-dish rims with the hollow side facing up.
Skip it if you have a flat or differently oriented rim; the Yakima 8007076 is specified for named baskets and spare tires up to 35 inches.
Choose the Front Runner clamp if your rack has two usable slats and your raised-dish rim can sit hollow-side up. Its wheel-profile and orientation requirements are the main fit boundaries, despite its deep-offset accommodation.

View on AmazonCheck the rack interface before choosing a mount
The rack’s attachment style can rule out a mount even when its tire-size limit looks suitable. The RANSOTO Universal Steel Roof Rack Carrier uses four rubber clamps under the rack and a J-hook through the wheel, while the maXpeedingrods Universal Carrier describes separate methods for basket floors and platform racks with T-slots. The Yakima Spare Tire Carrier is specifically listed for LoadWarrior, MegaWarrior and OffGrid baskets.
The BajaRack Floor Mount is intended for rack flooring but excludes mesh flooring. These are not interchangeable interfaces, so identify whether you have crossbars, a basket floor, slats or a T-slot platform, then compare that surface with the product’s mounting instructions.
Also measure the available area: the YSKMZKK Adjustable Roof Carrier lists a 12 × 4.7-inch base and elongated slots, but its listing still advises measuring the rack before ordering. A stated 35-inch tire limit does not confirm that the mount fits every rack or wheel.
Treat tire security and roof load as separate checks
A lock or vibration-control feature addresses only part of the risk of carrying a spare on the roof. The RANSOTO Universal Steel Roof Rack Carrier uses a wing nut that locks to the top plate by padlock, and the Sidasu Universal Tire Carrier lists a magnetic-base locking system with two keys. The Sidasu Heavy Duty Mount instead highlights rubber isolators for vibration reduction.
These features are useful to compare, but the supplied product details do not establish how any mount performs in a particular vehicle, at a particular speed, or on a specific road. Separately verify the vehicle’s roof-load limit, the rack’s rated capacity and the spare’s weight; do not treat a mount’s tire-diameter limit as a weight rating.
One listing illustrates why: the Yakima Spare Tire Carrier lists a 35-inch maximum tire size alongside an 11.02-pound load capacity. Confirm that stated capacity is suitable for your actual wheel before relying on that size limit.
How to Choose a Roof-Rack Spare Tire Mount
Tire diameter and stated load
Look for a tire-size limit that covers your actual spare, and check any stated load capacity separately. The RANSOTO Universal Steel Roof Rack Carrier, YSKMZKK Adjustable Roof Carrier, maXpeedingrods Universal Carrier, both Sidasu carriers and Yakima Spare Tire Carrier list fit for tires up to 35 inches. The Generic Crossbar Tire Carrier and BajaRack Floor Mount do not provide a maximum tire diameter in the supplied details, while the Front Runner Low Profile Clamp focuses on rim shape and offset.
RANSOTO lists a 35-pound load capacity; Yakima lists 11.02 pounds. Those figures make checking the weight of your wheel especially important.
Buyers with a confirmed tire under 35 inches can consider the stated-limit options; those with a larger or unusually heavy spare should seek explicit confirmation before ordering.
Rack attachment style and adjustability
Choose the mount whose hardware matches your rack surface, rather than assuming universal means every interface. The maXpeedingrods Universal Carrier describes basket-floor clamps and T-nuts for a platform T-slot, while the Sidasu Heavy Duty Mount fits crossbars 1 to 3 inches thick. The RANSOTO Universal Steel Roof Rack Carrier uses rubber clamps under the rack, and the Yakima Spare Tire Carrier is listed for three named Yakima baskets.
The YSKMZKK Adjustable Roof Carrier has eight elongated slots for horizontal and vertical positioning, but asks buyers to measure their rack. Basket owners should favour products with basket-floor instructions; platform owners should check T-slot compatibility; crossbar owners should verify bar dimensions and clamp fit before purchase.
Security, vibration control and removal
Compare the actual security and retention features with how often you need to remove the spare. The RANSOTO Universal Steel Roof Rack Carrier includes a padlock-based arrangement, and the Sidasu Universal Tire Carrier lists a built-in locking system with a magnetic base and two keys. The YSKMZKK Adjustable Roof Carrier includes a lock, while the Sidasu Heavy Duty Mount specifies rubber isolators for vibration reduction.
Yakima lists quick release for installation and removal, a useful distinction for buyers who expect to take the carrier off more often. The Generic Crossbar Tire Carrier describes a wing-nut quick-release design in its title.
These details do not prove theft prevention or reduced movement in all conditions; buyers should check the supplied hardware and installation instructions and favour a lockable design when security is a priority.
Which Roof-Rack Spare Tire Mount Should You Choose?
For a broadly compatible starting point with a stated 35-inch tire limit and included locking hardware, choose the RANSOTO Universal Steel Carrier, after confirming the clamp-and-J-hook arrangement fits your rack. If positioning flexibility is the priority, the YSKMZKK Adjustable Roof Carrier offers eight elongated slots and an included lock. For a basket or platform rack, the maXpeedingrods Universal Carrier describes mounting methods for both; for crossbars measuring 1 to 3 inches thick, consider the Sidasu Heavy Duty Mount.
Owners of specified Yakima baskets can look at the Yakima Spare Tire Carrier, but verify its listed 11.02-pound load capacity against the actual wheel. The Sidasu Universal Tire Carrier is a choice when its magnetic-base lock and two keys appeal.
Skip any option whose mounting interface or load limit cannot be confirmed for your rack and spare.
Related Buying Guides
Frequently Asked Questions
How do I confirm that a tire mount will fit my roof rack and wheel?
Check the mount’s stated tire-size limit, then compare its attachment method with your rack’s bars, basket, or platform. Confirm that the wheel and tire stay within the mount’s stated limits and that the rack can accommodate the hardware. If the product information does not establish compatibility, verify it with the seller or manufacturer before buying.
Will mounting a spare tire on the roof affect vehicle handling or roof-load limits?
It can affect handling, and the combined load must remain within the vehicle’s and rack’s limits. Include the spare, mount, and any other roof cargo when checking those limits; do not assume a tire-size rating confirms load capacity. Follow the vehicle and rack instructions, and avoid using a setup whose permitted load you cannot verify.
How should I protect a roof-mounted spare tire from theft and weather?
Use the mount’s locking hardware where provided, and check that the lock engages as intended; a lock can deter theft but does not guarantee prevention. For weather exposure, follow the tire maker’s care guidance and inspect the tire and mount periodically. Keep the spare secure, and recheck the attachment after installation and before travel.
Which mount should I consider for a basket or platform rack?
Look for a mount whose product information specifically describes attachment to your rack type. The maXpeedingrods Universal Carrier describes mounting methods for both basket and platform racks. Confirm that the method matches your rack and that the spare remains within the mount’s stated tire-size and load limits before choosing it.
What should I check about a mount’s load capacity before buying?
Compare the stated capacity with the actual wheel and tire weight, and include any relevant mounting hardware if the instructions require it. The Yakima Spare Tire Carrier lists an 11.02-pound load capacity, so verify that it accommodates your wheel. If a mount’s capacity is unclear or insufficient, choose an option with confirmed limits.
Final Words
For a general roof-rack setup, the RANSOTO Universal Steel Carrier is the leading choice in this group: it accepts tires up to 35 inches and includes locking hardware. First confirm that your rack accommodates its clamp-and-J-hook arrangement and that all load limits are met. Choose another mount when its specific interface better matches your rack, and skip any option whose fit or capacity cannot be verified.
