I just purchased a new trailer that came with 205/75 R15 tires. Any harm in going up to a 225/75 R15 tire? I would like the increased plys and load range. Thank you.
Op has not said what his new trailer GVWR is, or what load range tire is on it. He may already have D rated tires. If he has C rated oem, they would have to be adequate. If he wants, or needs a bit more cushion for his load, D rated Endurance would be a good choice.
