25 Seafari...55mph

[cdavisdb]

Old thread, but some new information. With my Owens 7000 lb bunk trailer and a 24 Seabird, I had no trailer problems and only a few tire problems in 10 years. After I switched to a 25 Seafari, same trailer, I started having tire problems, a lot. The Seafari is only a little heavier than the Seabird, but holds more gear and gas. Tire rating was above the trailer rating, so I figured to be ok. Apparently not so. I did some research and discovered that you should reduce the tire capacity rating by 10 percent for twin axles and 10 percent more for 65 mph. Put all that together and I was way under size on the tires. Went to 10,000 lb rated bias ply tires and have had no problems since.
