I would recommend you stick with your current size if that is why your trailer manufacturer recommends and just keep the tires inflated to their max psi, keep your speeds below 65 miles per hour and avoid overloading your trailer you should be fine.

However, I am concerned because you said you have (2) 10k axles yet you are overloading them when you are hauling between 24k and 26k. I would recommend you not exceed the capacity of the lowest rated component in your setup. In this case you are overloading your axles since you only have 20k in axle capacity.

I would not recommend going with an LT tire. I would stick with an ST specialty trailer tire. They are constructed better for trailer use with thicker sidewalls for carrying loads. LT tires are designed for trucks and should not be used on trailers.

For replacement tires that are the same size as what you have with the same capacity check out the Karrier ST235/80R16 Radial Trailer Tire # AM10248. I attached a review video for this product for you to check out as well. The max PSI for this tire is 90 psi. You will want to keep the tires inflated to that.

I attached an FAQ article on trailer tires for you to check out also.
