Buying Guide: Spare Tire Mounts For Trailers

What to consider when choosing a mount

  • Weight capacity: Most mounts handle 120–150 lbs. Match this to your spare tire weight and potential payload on the trailer.
  • Wheel lug compatibility: Ensure the mount supports your wheel lug pattern (4, 5, or 6 lugs) and the correct bolt circle diameter.
  • Tongue fit and clearance: Check that the mount fits your trailer tongue width and height; some mounts specify up to 4″ wide and 5″ tall.
  • Material and finish: Stainless steel or forged iron with rust-resistant coatings prolongs life in marine environments.
  • Installation effort: Some mounts require no drilling; others need bolt-on installation. Consider your trailer modification tolerance.

Mounting location and aerodynamics

Spare tire placement should balance weight distribution and ground clearance. Raised or sloped designs can reduce wind resistance and reduce ground clearance concerns on steep ramps or uneven roads.

Durability vs. convenience

Heavy-duty mounts emphasize longevity and tire security but may be harder to install. Lighter options are easier to install but might offer less long-term stability on rugged trips. Weigh the trade-off based on how often you switch tires or travel on rough terrain.

Compatibility with jet ski trailers

Jet ski trailers often use lighter frames and smaller tongues. Look for mounts that specify compatibility with boat trailers and similar tongue dimensions, and confirm that your spare tire pattern matches the bolt pattern supported by the mount.

What not to overlook

  • Inspect mounting hardware for rust and wear regularly, especially after exposure to saltwater or salted roads.
  • Maintain proper torque on bolts to prevent tire loosening during travel.
  • Store spare tires in a location that minimizes exposure to direct sunlight and extreme heat when not loaded.
