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.
Gdetrailer, that top tire show 225-E. All 205-15 are C & D that I am aware of.
For the OP watch your approved wheel width and clearance before you jump to 225s. May need new wheels. Keep in mind trailer suspensions do deflect significantly when turning sharp.
I have and recommend the Goodyear Endurance ST205R15-D. Speed rated to 80 something.
