I'm following this thread as I'm going to be putting new tires on my trailer this week. My tires are 5 years old and most of my trailering is highway miles. I have a single axle trailer with a Triton 18 Explorer on it. I'm estimating the total weight to be around 3,000 lbs. Currently it has Karrier Loadstar tires on it and the max pressure is 50 psi. I see the next jump up are tires with a max pressure of 65 psi - they are better tires though. My question is: If I opt for the better tires and run them at 65 psi is the trailer going to seem like its riding on concrete wheels or should I just stick to the 50 psi tires?
