I tow a 15T from SC to the 10,000 islands each year. I also tow back and forth to Charleston many times each year. I replace my trailer tires every 18-24 months. I make sure they are inflated to appropriate pressure. I purchase radial trailer tires speed rated at 81mph. My hubs and bearings are inspected and repacked/replaced at the first sign of issues. I have 2 spare tires mounted to the trailer. I carry a new hub/bearings and installation tools. I also carry a jack, tire tool, and various other tools (these are all neatly stored in a plastic box that rides in the boat until I reach my destination). Each time I stop I inspect everything. One time I had a small bulge on the sidewall I noticed when we stopped for fuel and I replaced the tire with a spare. Other than that- I have had no issues. I like to think that I can make it there and back without any assistance from the outside world- even if I have some sort of trailer issue!!!
