Expert Reply:
The B78-15 tire size you mentioned having on your trailer is an older tire size. The metric equivalent to this size is a 225/75-15 tire like the Provider Radial Trailer Tire # TTWTRTM2257515D. This tire has an overall diameter when inflated of 28.31 inches and a section width of 8.78 inches. It features a maximum load of 2,540 pounds at 65 psi and an excellent speed rating of 81 mph. It will fit 15 inch wheels with a width of 6 inches, 6-1/2 inches, or 7 inches.
I have attached a short video demonstration on this tire, along with a link that will take you to our available selection of 225/75-15 tires and wheels that you can look through.
