In order to find the right spare tire holder for your pontoon boat trailer you can take a measurement of the bolt pattern. I have attached a helpful article that explains how to take the measurement.

Once you determine what the bolt pattern is on your wheel you can check out the attached link for the spare tire holders we offer. One of the carriers we offer is the Fulton Hi-Mount, part # FSTC1000301. This will work with wheels that have a 4 on 4 or a 5 on 4-1/2 bolt pattern, and fits frames up to 3 inches wide and 4 inches tall.

You will also want to measure the trailer frame you want to mount the holder on as they can vary as well.
