Trailer tires have a wide range of load capabilities, depending on manufacturer and model. Over time, with my old toy hauler, I learned to only use Load Range E tires. I used Maxxis, Goodyear, and Carlisle trailer tires at various times, all with pretty good results, unless I picked up a nail or something like that. Only endured one blowout, and I am certain it was a nail that dropped the pressure and ran the tire hot. I ended up replacing tires from wear about every 2-3 years, because the right front always scuffed down well before the others. My trailer was over 10,000 lbs fully loaded.
