It supports up to 120 pounds and offers an extended rectangular rear plate with long bolt holes for various lug patterns. Best for: budget‑conscious buyers seeking reliable universal compatibility. Caution: lower load rating means avoid very heavy tires on frequent long trips.
PAULINN 3‑Nuts Upgraded Mount
The PAULINN 3‑Nuts solution offers up to 180 pounds of load capacity with a robust welded frame and a raised back plate. It accommodates a wide range of lug patterns from 4 to 8 lugs, including 4″ to 6″ bolt patterns, making it versatile for utility trailers, boat trailers, campers, and RVs.

Liamoy Spare Tire Carrier with U‑Bolt
The Liamoy U‑bolt style carrier mounts on trailer frames up to 2″ or 3-4/5″ wide and fits up to 15″ tires for 4 or 5 lug wheels. It features galvanizing for weather resistance and straightforward installation. Best for: side‑mount configurations and simple retrofits. Limitation: may not be ideal for very heavy tires over longer trips due to the lower load design.
Buying Guide: Key Purchase Considerations
- Load capacity: Match the carrier’s rating to your spare tire weight and anticipated road conditions. Higher capacity supports larger tires and rougher roads.
- Bolt pattern compatibility: Confirm the lug count and bolt circle sizes (4″, 4.5″, 4.75″, 5″, 5.5″, 6″, or 8 lugs) match your wheel.
- Mounting design: Look for a raised/angled mount to reduce wind resistance and provide stable tire alignment.
- Corrosion resistance: For marine or humid environments, stainless or galvanized steel options resist rust longer.
- Installation ease: Consider the number of fasteners and whether the design simplifies alignment during mounting.
- Security features: Some models include anti‑theft or locking mechanisms; assess if this matters for your trailer and location.
