IMHO...always wonder about ST trailer tires and even higher class LT tires on trailers that are close to published axle limits/ratings
Some have argued no different than that same tire on a TV, but most TV's are not at their axle limits/ratings, while aired up to max sidewall PSI
Plus, trailers experience a different path & conditions than TV's...
First they are normally aired up to their max ALL the time *AND* most are at max loading (at limits/ratings)
They have a less compliant suspension, generally, and no shocks, etc, etc. So they must 'take it' while the TV has a more compliant suspension (ride quality) that takes much off of its tires when striking something going 65MPH. Some folks do improve their trailer suspension, but a rarity
They see more squirm than TV's while cutting tight turns...like jack knifing to jockey into a tight spot. Ditto out on the road. While TV's have a steer axle that takes that sidewall stress away. Plus trailer axles are very close together compared to a TV's two axles...another 'takes away' that side wall squirm
An example of this trailer tire squirm are the reports that commercial tires that do NOT have a safety bead...comes off its tapered bead to lose air. that side loaded, squirm while maneuvering does that. While lower class tires have that safety bead to keep it on
Since most trailers take a smaller radius than the TV, they sit stuff that the TV misses.
Just some IMHO thoughts on this matter...
