Can Slightly Smaller Spare Tire be Used on Trailer to Get Home
Question:
Can I use a ST 175 tire as a spare to get me home on a trailer with ST 185 tires on it?

Helpful Expert Reply:
Generally, I do recommend that all tires on your trailer be the same size at all times, so ideally your spare will match the existing tires on your trailer. With that being said, the difference between a 175/80-13 and a 175/80-13 tire is only 0.3 of an inch, so if needed in an emergency, the 175 spare tire should be fine to get you home.
To be on the safe side, I do still recommend obtaining a matching spare tire when you are able. I have attached a link that will take you to our available selection of 185/80-13 trailer tires for you to look through. If you have a 5 on 4-1/2 bolt pattern, I recommend the Loadstar ST185/80D13 Bias Trailer Tire with 13 Inch Galvanized Wheel # AM3S334. This tire and wheel combo has a 1,725 pound maximum load at 65 psi.
I have also included a couple of articles on trailer tires that you may find helpful.
