High profile tires on off road packages on trailers. hmmm

True, true, and maybe - depends on which particular tire size they are.

One advantage of them is higher ground clearance, which reduces the chances of rocks and other objects snagging something on the underside of the trailer.

In some cases, they're sold with a "high-lift" axle option that also increases ground clearance a bit.

Some trailers have low-hanging dump valves which are prone to road damage, so a couple extra inches of height can be worthwhile - particularly if you like to take the trailer off paved roads.
