Expert Reply:
If the trailer is made for 185/80-13 tires, then I would stick to that size. But if you need to go to a different size, there are some things to consider. Going to a smaller size like the 175/80-13 will not cause problems in terms of the tire interfering with the trailer or fenders, but you will have a lower capacity.
For capacity, you will want to go by the axle capacity. This information can usually be found on a plate or sticker on the trailer frame or tongue.
If you decide that you need to go to a 14 inch tire/wheel, you will need to make sure that the bolt pattern matches, the capacity is enough, and that the tire does not interfere with the trailer or fenders. A 205/75-14 tire will be 8 inches wide, and 26-1/8 inches tall. A 185/80-13 will be a little more than 7-1/4 inches wide, and 24-11/16 inches tall.
The tire pressure is only an issue when it is too low, or the trailer is loaded beyond the capacity of the tires. Trailer tires should always be inflated to the maximum psi rating indicated on the tire.
