The tires on my trailer are size A78-13ST. Can anyone tell me what size that would be in standard size? Example 175/80R13 not saying that is the size, but you know what I mean.
You will want to consider how far you are towing also. Radials run cooler than bias. I had this size on my boat trailer and just replaced with Carlisle radial. Trailer is not handy or I would give you the exact size. It pulls great. Carlisle is a 6ply trailer tire. I also run these on a heavy duty enclosed utility trailer. Pull it over all central U.S. and haven't had a problem yet.
