Its telescoping design fits frame widths from 52″ to 72″, offering broad compatibility with many RV trailer configurations.

The powder-coated finish enhances rust resistance for long-term use in varied climates. This model is a practical choice for owners seeking a low-profile solution that doesn’t erode cargo area or trailer appearance.
Camco RV Ladder Mount Bike Rack
The Camco ladder-mounted rack is designed for RV ladders, offering a straightforward way to carry two bikes while keeping ladders accessible. It supports up to 60 lbs total, which makes it suitable for most standard adult bikes or a couple of lighter options. While it excels in providing additional hauling capability without taking up bumper space, potential buyers should verify ladder compatibility with their specific RV model, as some bike frames and wheelbases may not fit every ladder design. The rack folds for storage when not in use, which helps minimize drag and exposure to the elements.
Delmoar Trailer Spare Tire Mount
Delmoar offers a universal spare tire holder designed for utility trailers and similar platforms. Built with heavy-duty steel and galvanized fittings, this mount is durable and weather-resistant. It features a two-tier washer arrangement to protect the tire and prevent shifting, with an extended rear plate and adjustable bolt holes to accommodate various lug patterns and bolt configurations. The design supports up to 120 lbs, making it suitable for a wide range of tires. Its adaptability is a strong point for RV owners who also tow trailers or boats and need a flexible mounting option.
GADFISH Spare Tire Carrier
The GADFISH spare tire carrier emphasizes heavy-duty construction with a reinforced triangular frame and a robust back plate to secure the wheel. It accommodates multiple lug patterns, including 4, 5, and 6 lug configurations, across common tire diameters. The design anticipates vibration and wear, offering a durable solution for rough roads or longer trips. The product’s build quality aims to minimize tire movement, reducing noise and potential loosening during transit, which is a meaningful consideration for RV travelers who demand reliability and longevity.
Thetford RV Ladder Mount System
The Thetford ladder mount system is designed for versatile use on RV ladders, with a lightweight aluminum construction suitable for multiple portable items such as waste totes, bikes, or chairs. It supports up to 50 lbs and uses metal brackets with screws for secure mounting. An included nylon strap helps keep items tethered during travel. This option is attractive for owners who want a flexible carrier that can adapt to various equipment beyond tires, though it may offer less tire-focused weight capacity compared with dedicated tire mounts.
Qualward Spare Tire Mount Bracket
Qualward presents a spare tire bracket with upgrade bolting design to fit various 4, 5, and 6-lug patterns. It accommodates trailer tongues up to 4 inches wide and up to 5 inches tall, making it a versatile choice for many utility trailers and boat trailers. The heavy-duty forged iron construction supports up to 150 lbs, and the powder-coated finish provides rust and corrosion resistance for outdoor use. The broad compatibility makes it a reliable option across several trailer types, though installation may require precise alignment to match lug patterns on the tire.
Adamoss Trailer Spare Tire Mount
The Adamoss spare tire mount emphasizes security with an upgraded three-nut locking design to minimize vibration and noise, reducing the risk of nut loosening during travel. The locking mechanism protects against theft and supports up to 160 lbs. It is designed for universal compatibility with 4, 5, and 6-lug patterns, including various bolt pitches. The robust welded tubular frame and triangular construction deliver solid support, making it a strong choice for heavier tire configurations or frequent travel where durability is paramount.
Buying Guide: Key Purchase Considerations
- Weight capacity and tire size: Confirm the mount supports your spare tire’s diameter and weight. Some models handle heavier tires up to 150–160 lbs, while others are better suited for lighter setups.
- Lug pattern compatibility: Ensure the carrier matches your wheel’s lug configuration (4, 5, or 6 lugs) and pitch circle diameter to avoid misalignment.
- Mounting location: Under-frame mounts save exterior space but may require extra clearance during travel. Ladder mounts improve accessibility but could restrict ladder use or add complexity.
- Corrosion resistance: Outdoor exposure demands powder-coated or stainless-steel components to resist rust over time.
- Security: If theft is a concern, look for locking provisions or bolted designs that securely fasten the spare tire to the carrier.
- Installation complexity: Some models offer simple bolt-on installation, while others require precise alignment or multiple brackets. Consider professional installation if uncertain.
- Multi-use capability: Some mounts double as bike or gear racks, offering flexibility for seasonal travel needs.
- Durability in transit: Look for reinforced frames, backplates, and vibration-resistant features to minimize movement and wear on tires.
When choosing a spare tire mount, weigh the need for space efficiency against installation complexity, ensuring compatibility with your RV’s frame, ladder arrangement, and typical travel routes. The options listed provide a spectrum of capacity and mounting styles to accommodate different RV lifestyles, from compact travel trailers to larger motorhomes. Always verify product specifications with current listings to confirm compatibility before purchase.
