A tire marked 155r12-76 is an automotive tire, but we should be able to get you something close. Trailer tires are typically less expensive than automotive tires because they do not have to meet the same safety standards since they are not designed for use on a vehicle transporting people. All trailer tire numbers will start with the letters ST, which stands for Special Trailer Tires.

Your 155/12 tires should be 6.1" wide. The closest trailer tire size we offer is ST145/R12, which is 5.7" wide. I've provided a link to our selection of tires/wheels in this size. If you have 5 lugs, I recommend # AM31199DX. If you have 4 lugs, I recommend # AM35351DX.

Trailer tires should be replaced every 5 - 6 years after installation, regardless of the mileage or use. If your trailer is stored outside or exposed to direct sunlight for long lengths of time, you may need to replace them more often because dry rot can set in quickly. I recommend replacing all of the tires at the same time so that they wear evenly. Once you have changed all of your tires and wheels to trailer sizes, it will be easier to find replacements.

I've attached links to some articles on trailer tires that may be helpful.
