You will get more accurite response by posting some tech info on your current trailer and tires.
Such as I see a tripple axle trailer in your profile however we don't know what the trailers GVWR and its axle rating or a actual scaled axle weights.
What size tire and what load range are your present tires ?
As mentioned the XPS Ribs and the Bridgestone R-250 both a commercial grade tire and are a rib design tread with a all steel ply carcass. Their tops for a trailers tire requirements.
The M895 is a steering and drive tire that doesn't have the ribbed tread but still a hands down superior tire to any ST tire out here.
I'm guessing here but your tripple axle trailer with 15" wheels may have 5200 lb axles.
Any of the LT E tires at 2680 lb capacity or 3042 lbs capacity such as the Goodyear Wrangler H/T or Firestone Transforce H/T or BFG Commercial H/T or Uniroyal Lerado HD-H are superior tires to any ST tire brands.
