I appreciate the information on your successes with the Cooper line of tires. Did you buy the recommended Coopers for your trailer?
Yes. The 16k tri axle GN stock trailer now has six Cooper Discoverer HT 3 LT235/85-16 E tires. This trailer sits a lot but is required to haul a 16k load 300-400 miles at 75 mph legal speeds when needed and on a moments notice nite or day.
I've used dozens and dozens of tires on my trailers over the years. I've found a good tire tread pattern for a trailer needs a minimum of one solid rib in the tread for straight line running especially on a trailer. Some LT tires may have two solid ribs on the outside of the tire or may have a solid center line rib for good straight line tracking.
Then of course we have the XPS or the Bridgestone R-250 all ribbed tire. Both are a commercial grade all steel ply carcass tire
More solid unbroken ribs the better tracking/less sway issues.
Some sipping is good as they give the tire braking traction on wet pavement.
Trailers are very forgiving about tires unlike a truck however a tread pattern like a all terrain, or worse a mud terrain ,can lead to tracking issues with lots of sway and sliding the tires on wet pavement on severe braking events. Just my thoughts.
