Time for Tires

[Tango]

Hey experts,
I'm very new to RV'ing and need a little sanity check for replacing my tires on my 5th-wheel. I have a small (19') 1984 Alpine Lite (dual axle) that currently has ST225/75/15D tires that need replacing. These are tires that came on the trailer and they seem rather old and actually over-rated for my rig. My trailer specs are GVWR:6292 lbs, GAWR (front and back)-3196 lbs, P205/75/R15 @ 32psi. If I divide the GVWR by 4 that's 1573 lbs/tire. My question.. Is a more standard duty light truck P205/75/R15 load rated above say 1600 lbs be a good choise as replacement tires? They would be cheaper and should give a better ride.
Help Please...TANGO

Why argue with success. With all of the tire troubles that we read about on the boards, you have the ability to run more tire than required. Why skimp?

I'd run the "Ds"� and run them at 65lb..
