30 miles from our destination my TPMS indicated low pressure. Indeed it was. Had gone from 65psi this morning to 52 psi after 200 miles. Bought all four Goodyear Marathon ST225/75/R15 2 months ago. Al...

I think the OP is concerned about what hidden internal damage the tire may have suffered when running under inflated.
This is a valid concern. Especially since ST tires do not have to pass an underinflation test like LT tires do.
I would replace the tire. If the tire has been damaged, a blowout can occur without warning. The resulting damage to the TT that can occur will likely be MANY times the cost of replacing the tire.
I am no tire expert, but I find it extremely hard to believe that a tire will experience internal damage from running 20% under pressure for a total of about 300 miles. It may be different if the tire pressure had gone extremely low. But 52 pounds in a 65 pound tire shouldn't be terminal by any means.
Again, just my opinion as I am not a tire expert. I agree with those that think this is either a valve or tire bead leak, or perhaps a small nail puncture with the nail effectively sealing most of the leak. This is a new tire. Get it fixed.
