Thats weird cause around here all the trailers come with carlisle on them and I've had 2 sets myself and never a problem with the tires on a tri axle no less. I do have one radial tire on there now and it seems to be wearing much better then the bias tires and is also cooler when I touch the side walls after a trip
Must have got some of the few Carlisle tires. I got all the way from Delphos to Marion IN, about a hundred miles before one blew. Next one that blew was in Indy another 85 miles on a new single axle cargo trailer with just a light load.
