The LT E XPS Ribs or the Bridgestone R-250 are both a all steel ply carcass commercial grade tire at 3042 lb capacity and are the holy grail for 16" wheels and 5.2k lb and 6k lb axles. The R-250 is quite a bit lower priced. One isn't any better than the other.
Now if your trailer has 7k lb axles then the Goodyear G614 RST in a LT235/85-16 G at 3750 lb and 110 psi.
Or the Sailun S637 ST235/80-16 G at 4080 lbs at 110 psi. Make sure your trailers wheels are approved for 110 psi.
Both tires are a commercial grade all steel ply carcass and are tops for heavy trailers requiring 7k axles.
When replacing OEM tires on a the tires capacity should meet the trailers axle ratings.
And of course do your homework on proper wheel well and between the tire clearances for your particular trailer. We can guess but a good truck tire dealer can assist you with clearance issues.
