I have included a link that includes the tires that we currently carry that will fit your 15 by 5 rim. Depending on your trailer capacity, you will need to select the correct load range tire to match.

These tires will fit the rim that you specified, but please note that the tire size that you indicated (235/75-15) is a passenger vehicle tire size, and is not recommended to be used on trailers. A tire that is 235/75-15 may physically fit on a 5 inch wide rim, but is not advised to be used as a trailer tire.

The appropriate tire size for a 15 by 5 inch trailer rim is a 205/75-15. This tire size is significantly different than the 235/75-15 that you mentioned you already have on your trailer. Due to the difference in tire size, the trailer may not ride level. It will work as a spare for your trailer to use in an emergency situation.

If you plan on using your trailer frequently, I recommend using matching tires and wheels that are specifically designed for trailers. Or getting the same tire and wheel combination that you currently have so that the spare will be an exact match.

I have included a link to the tires available for your wheel, and several helpful articles about trailer tires for your reference.
