10 Best Spare Tire Lock 2026 in the United States

The GADFISH Spare Tire Carrier is a solid choice for securely mounting spare tires on trailers, trucks, vans, and boats, thanks to its wide compatibility with various lug patterns (4, 5, and 6 lug wheels) and multiple bolt pattern sizes. This makes it a versatile option if you have different types of wheels or trailers. Made from durable alloy steel with a powder-coated finish, it offers good protection against rust and weather, helping it hold up well outdoors. The carrier's heavy-duty build supports up to 150 pounds, so it’s reliable for most standard spare tires.

Its locking mechanism relies on strong screws and a reinforced triangular design to keep the tire firmly in place, reducing the risk of losing it while driving. Installation is user-friendly, requiring no drilling and only a wrench, which is great if you want to avoid complicated setups. You can also adjust the height of the steel beam to suit your trailer’s needs. One thing to keep in mind is that it does not come with a separate lock included, so you might need to purchase one separately if theft prevention is a priority.

The carrier has a smooth finish from sandblasting and powder coating, though very harsh conditions over time could still wear it down, so occasional maintenance would be wise. Customer feedback is positive, reflecting its reliability and ease of use. This carrier is highly suited for anyone looking for a durable, adaptable, and easy-to-install spare tire mount with decent weather resistance, especially for trailer or boat owners.

The FIERYRED Trailer Spare Tire Mount with Lock is a solid option for those needing a secure and durable way to carry a spare tire on utility or boat trailers. It fits a broad range of wheel bolt patterns (4-lug and 5-lug, including 3.94”, 4”, 4.25”, and 4.72”), making it quite versatile for many trailer setups. Constructed from forged iron with solid welding and zinc plating, it resists rust and corrosion well, which is important if your trailer is exposed to wet or salty environments. The mount can safely hold tires weighing up to 120 pounds, so it’s suitable for most common trailer tires.

Installation is straightforward without any drilling required; it comes with all necessary mounting hardware, and the bolt-on design means you can put it on or take it off easily. The lock adds peace of mind by keeping your spare tire secure, and it includes two extra keys in case you misplace one. The mount’s design is compact and close to the trailer, reducing wind drag and raising the tire slightly for better ground clearance.

The iron material makes it a bit heavy, and while zinc plating offers corrosion resistance, it may not be as long-lasting as stainless steel in very harsh climates. Some users might find the mount’s size bulky depending on their trailer space. For those seeking a reliable, easy-to-install spare tire carrier with a good locking mechanism for their trailer or boat, this product effectively covers the essentials.

The CURT 23562 Spare Tire Lock is designed specifically for side-mounted spare tires, making it a good fit if your vehicle uses this setup. It is made from strong alloy steel with a polished chrome finish, which helps protect against rust and harsh weather. The key lock mechanism is straightforward and comes with two keys, so you have a spare in case one is lost. Its compact size and simple design suggest that installation should be quite easy for most users.

The sturdy steel construction offers solid protection against theft, and the chrome plating adds durability and a clean look. This lock is tailored only for side-mount spare tires, so it won't work if your spare tire is mounted underneath or on the rear door. While chrome plating provides some weather resistance, it may not be as long-lasting as other heavy-duty coatings in extremely harsh environments.

This lock is a sensible choice if you want to secure a side-mounted spare tire without complex installation or maintenance. If you need a lock for a different spare tire style or want maximum weatherproofing, you might want to explore other options.
