Single Axle VS Double/tripple Axle Travel Trailers & P/LT Tire De-Rating Factor ?

When using a LT tire on a single axle Airstream trailer instead of a ST tire does the de-rating of 10% or the .909 factor rule I keep reading about really need to be considered in the decision when deciding the load requirements of a tire? Every thing I have read just says a ST tire when used on a trailer. I have only read about the additional stress factors that are put on the tires when used on double/triple axles. Correct me if I am wrong, I thought the stress factors on the side walls of a tire on a single axle travel trailer were a non issue when compared to the trailers using double/triple axles.

De-rating only applies to P-rated tires (passenger tires).

The single axle trailers are light. LT is almost overkill. Look to see what Andrew Thomson is putting on those at his dealership.
