They make a load range D now
I'm going to need some new tires, ST205/75R15. 8 years ago I bought the Goodyear Marathon, in a load range C. Actually all the trailer tire brands of that size were load range C at that time. No...

When we bought our 2014 TT new, standard tire size was LRC ST205/75R15 in a generic Chinese brand. LRD Marathons were available as an option so we got those and the section width went to 225. IMO, wider is good. Max. sidewall pressure in the LRD Marathons is 65 psi and that's what I've used from day one on our 7K lb TT.
Even with the higher load range, inflate them to the sidewall max. You'll have a higher reserve load capacity that way which is a good thing and will reduce the risk of a blowout. It's probably a good idea to check the psi rating on the rims. Can always run the new tires at a lower psi *if* you had to per load inflation tables.
If you ran on the Marathons for 8 years, most people replace any brand of ST tire at around 5 years old.
We're about to install new Endurance in the same width but they now become LRE. Our rims are good for 80 psi max, so that's what I going to inflate them to.
