Tire Tread on a TT

Can someone explain to me how an aggressive/knobby/offroad tread on a trailer tire has any significant benefit while towing.

I've owned three 5th wheel rv trailers since the mid '80s but non ever went off road other than pulling into a construction work site at times.

Having towed non rv trailers full time on paved highways what I've found from actual experience is a AT or MT with large lugs and voids used on a road trailer loose traction quick on dry and especially wet pavement during hard braking events.
And like someone pointed out they wear fast....simply not a good tire tread for a working trailer. This type of work the trailer needs a long lasting tread type/good highway traction in all kinds of weather.

Now a rv trailer used in off road conditions would require a tread with larger lugs and voids.
