Modern Trailer Tire Replacement for a B78-14 Tire
Question:
What is the proper replacement size for older tires,B-78-14? I would like the same tire but with a narrow width/track

Expert Reply:
The modern equivalent of a B78-14 is a 175/75-14 or a 185/70-14. That said, these are not very common trailer tire sizes nor do we have any options in this size. The closest size we have is a 205/75-14 like the Provider ST205/75R14 Radial Trailer Tire part # TR20514 which measures 26.14" diameter x 8" wide. In order to go with a narrower option you would need to step down to a 175/80-13 like the Provider ST175/80R13 Radial Trailer Tire part # TTWTRTM1758013C which measures 24.02" diameter x 6.97" wide. If you can let me know your bolt pattern, I can then see about getting you a new wheel to go along with this size tire.
