The closest tire size to the ST155/80R13 you have is the ST175/80-13.
I did some calculations on the tire sizes and found that the difference between the 175/80R13 and the 155/80R13 is pretty small.
The 175/80 is 24 inches inches tall whereas the 155/80 is 22.7 inches tall for a difference of 1.3 inches total, but that difference needs to be split since the overall diameter is split since the wheel rotates on the axle. So basically the wheel will take up an additional .65 inches of your fender well.
The width difference is pretty small at .78 inches. So basically 3/4 of an inch wider
For a tire you would want the part # TTWTRTM1758013C made by Taskmaster as it is a radial tire with a higher 81 mph speed rating. Most trailer tires are only rated for 65 mph.
