Your B78-13 sized trailer tire has a metric size of 175/80-13. However, a P175/70R13 is a passenger vehicle tire and I do not recommend that it be used on a trailer. Trailer tires have special designs with stronger side walls so that they handle vertical loads from trailers.

I recommend the Kenda Karrier ST175/80R13 Radial Trailer Tire - Load Range D Item # AM10210. It is a radial special trailer tire that provides excellent traction in wet and dry conditions. It fits 13 inch wheels and has a maximum load capacity of 1,610 lbs at 65 psi. The Kenda Karrier Item # AM10210 provides a smooth ride, runs cooler than a bias ply tire, and is excellent on highways.
