Though I do have a 10 ply tire option for you to check out, it will be an ST tire, not LT. We currently do not carry any LT tires as they are designed predominantly for automotive use. They can be used on a trailer/5th wheel as they will have a heavier sidewall than a standard car tire, but ST, or Special Trailer, tires are designed specifically for use on a trailer. They will have a more robust sidewall than an LT tire, even when they have the same ply rating. This is so they can handle heavier loads and the stiffness will keep the load from swaying back and forth.

With all that being said, check out the Taskmaster Provider ST225/75R15 # TR225LRE. This will match your current tire size, but it has an E load rating, 2,830 pounds at 80 psi, and is 10 ply. This is also radial and has an M speed rating, or 81 mph. So it's not an LT tire, but it is very sturdy and will be the tire I recommend for you.
