Trailer tires for dirt road/rocks

[Dirty30]

I use an enclosed cargo trailer to haul 4door ranger which is also a base camp. Pulled panels and insulated walls, ceiling, floor. Have a propane stove with chimney for heat. I’m find myself driving a lot of dirt/gravel roads. Plus the normal rocky/dirt forest service roads. I’ve already had a few flats but looking to replace all 4 this year. Wondering if anyone had an insight /experience with a tire that would fit these needs? Drive lots of highways also.

What size tires does it use? The easy answer is to find an LT E or F rated truck tire, if they'll fit.

Goodyear endurance work well on my 3 horse trailer. Plenty of highway but a bunch of dirt roads and rocks too.

I thought you didn’t want a truck tire on a trailer because they have too much flex?
