Question:
What is the replacement size for A78-13St
asked by: Elaine
Expert Reply:
The metric equivalent of an A78-13 tire is a 175/80-13. This size is available in load range B, # AM1ST74, rated for 1,100 pounds at 35 psi.
It also comes in load range C, # AM1ST76 for bias ply or # AM10199 for radial, both rated for 1,360 pounds at 50 psi.
And there is also a load range D in this size, # AM1ST77, for bias ply and # AM10210 for a radial both rated for 1,610 pounds at 65 psi.
Radial tires run cooler and track better than bias ply tires but bias ply tires are better for off-road applications. I have included a link to our articles on tire sizes and trailer tires in general.
