Buying Guide

What to look for in a bolt-on spare tire mount

Key factors include lug-pattern compatibility, weight capacity, mounting surface area, and corrosion resistance. Look for reinforced back plates, triangular or multi-layer frames, and welded joints for long-term stability. A raised or angled mount can improve tire clearance and reduce road debris contact.

Which mount is best for your trailer type?

Boat trailers often benefit from higher corrosion resistance given exposure to saltwater. Utility and cargo trailers prioritize universal lug compatibility to simplify spare tire choices. RVs and campers may require mounts with higher load capacity and anti-theft features.

Material and finish considerations

Industrial-grade solid iron with sandblasting offers durability and rust resistance. Powder-coated finishes extend life in harsh weather. Avoid inexpensive finishes that may rust quickly in outdoor environments.

Installation and maintenance tips

Follow manufacturer-specified torque and alignment during installation. Regularly inspect bolts and the back plate for signs of wear or loosening. Clean and re-seal exposed metal to combat corrosion in salty or humid conditions.

How to choose between security and ease

Spare tire mounts with anti-loft or dual-nut systems provide additional security but may require more frequent adjustments. Simpler, single-nut or locking-ring designs offer quicker maintenance, at a potential trade-off in theft resistance on very long trips.
