I honestly, the first thing I would do with a single axle trailer is ditch the factory tires and get some decent ones on it. Some Carlisle or Goodyear Endurance. Camper tires are paper thin and not the best. The ones that came on mine, weren't even rated to hold GVW of my camper.
X2 on the tires, the tires on my new camper lasted ~1.5 years and about 1,000 miles before one blew, and tore the crap out of the side of the camper.
Put on the Goodyears and no problem since.
