We don't carry Goodyear Marathon tires, so I couldn't say for sure but the recommended tire pressure would be listed on the tire's sidewall. Typically, you'll want to inflate the trailer tires to the max pressure on the tire sidewall in order to realize the full load capacity of the tire.

The Karrier ST205/75R14 Radial Trailer Tire - Load Range D Item # AM10235 will be inflated to 75 psi when cold, but I wasn't able to find any information specific to the Goodyear Marathon online, so you should be able to check on the side of the tire for the required psi.
