The B78-13 ST tire size translates to a ST175/80-13 size tire. The overall height of the ST175/80/13 tire is 24 inches and the overall width is approximately 7 inches.

A popular replacement tire would be the Karrier ST175/80R13 Radial Tire, # AM10199. This radial tire provides excellent traction and has a maximum load capacity of 1,360 pounds at 50 psi. Special trailer tires must be inflated to their maximum air pressure otherwise the amount of weight that the tire can carry is reduced.

I have included a link to a few other ST175/80/13 tires that are available.
