The only tire I would recommend in the Tredit line is the Sailun S637 235/85-16 G load range at 3750 lb capacity at 110 psi. These tires were orig a LT but Sailun changed their letter designation to a ST tire so they wouldn't have to pay a higher import tax rate on LT tires vs the ST tire which being a niche tire isn't taxed at a higher rate. Trailer owners with 6k or 7k axle are using them with good success. I've seen no complaints on all type of trailering websites....unlike any brand ST tire.
For 6k axles the all steel ply carcass commercial grade Bridgestone R-250 or Michelin XPS Ribs are tops.
