StirCrazy - good comments here about LT vs ST specs and testing. What hasn’t been mentioned yet is that ST have stiffer sidewalls for the tire scrubbing that will happen on tandem and triple axle trailers. LT are designed with more margin and to higher standards, but they are designed for a different application than ST. I would recommend sticking to ST, and specifically recommend looking at Sailuns (that I have good experiences with - besides, much cheaper than a good LT tire).

yup and that's what I have always said myself, but I was looking into it as a few new rv's are coming out with LT tires, so it muddies up the water. I was going to go with sailun but after talking with them, they should be run at 110psi not at 80, so that would mean I would need new rims also. more to think about.

I've run Sailun's at less than 110 psi, but not as low as 80 psi. I ran mine down at 90-95 psi, with no issues and they lasted 6+ years and still looked good. I had a triple axle at the time and my load was about 5,000 lbs. per axle, so they were way over tired.

ya I was just going by what sailun told me. They said they should be run at full pressure for best tread wear, fuel economy and tire life.

That sounds like typical CYA. If they say you can run the pressure you feel is suitable for your trailer, then when someone ruins a tire due to excessively low pressure, they blame the company because they said it was okay to run lower pressure.
