Yes, st tires are designed to be able to sit idled for longer than lt tires. One of the drawbacks to using a lt tire on a trailer.
I have LT tires that are 5 years old that sit on concrete in the TX heat that don't look anything like that. I will be using the trailer this week with those tires and I am generally paranoid about trailer tires having three ST tires come apart on me.
I will replace our 5 year old LTs (with another set of LTs) before we do any 1000 mile driving on 100 degree interstates this summer.
