I purchased a new Starcraft hybrid a few years back. It was a 21ft with a slideout. It came with load range C tires, Carlisle as I recall. I don't know the weight of your trailer but the problem with LRC tires is that they don't carry much weight. I had a blowout soon after I got the trailer. I watched the pressures and was not overloaded. It was cool outside and I had not hit anything in the road. The problem was that the tire was spec'd right at the dry weight of the trailer. I was overloaded as far as the tire was concerned. I was not overloaded as far as the trailer weights said.
Point here is, I don't think the brand is as important as the load carrying capacity of the tire. I would trade them in and go up a category. Check the numbers on the tire against the max weight of your trailer and then give yourself some extra room. I have Maxxis on my current trailer and have been happy with them. Lots of miles in the last 4 years.
