This is a pretty good overview of preparation, tire safety, and various other issues to make your towing experience and your camping trip a success.
The information about increasing highway speed with the tires mentioned does bother me. Going much faster than 65 mph while towing doesn’t take into consideration other factors besides the tires and their integrity. Wind speeds, wind pressure from large trucks, and surface conditions matter greatly. Driver error is much more likely too. Our towing experience is far less than our driving experience overall. Please drive conservatively.
