Interesting article on tire rack about tire applications

This is the paragraph that caught my attention

Also consider that Special Trailer (ST), as well as Light Truck (LT) tires are fully rated for trailer applications. This means ST- and LT-sized tires can carry the full weight rating branded on the sidewalls when used on a trailer.

As did this one

However when P-metric or Euro-metric tires are used on a trailer, the load capacity branded on the sidewalls must be reduced by 9%. This means P-metric or Euro-metric tires with a maximum branded load rating of 1,874 lbs. for use on a car is only rated to carry 1,705 lbs. when used on a trailer.


here is the link to the entire article

    Sure am glad my trailer mfg. installed LTs as OEM.
    Yes, it depends on the manufacturer and the size of the trailer.

    Usually it requires a large size LT tire to carry the same capacity of a smaller size ST tire. Then cost and tire clearances become an issue.
