From what I heard from a tire dealer there’s a reason why they are called ‘trailer tires’. When asked, he said that trailer tires have heavier sidewall construction to help deal with the scrubbing (e.g. twisting) that occurs on multi-axle configurations...Just saying, but I’m no expert.
ST tire manufacturers propaganda for several reasons. One biggie is...
FMVSS 571 tire testing
The testing for bead unseating resistance is identical for a ST and LT tire.
The testing for (1) bead unseating resistance and (2) strength were identical for tires representative of moderate to heavy 5th wheels and thus no advantage is given to either tire type.
Tire dealers that don't know this simply pass along any mis info as we know this to be. Size per size they both stand up to side stress issues however one has had in the past a terrible history of sidewall zippers and mostly tread delam issues.
