Tire Margins on 2619

[Frenchy]

Can someone find out what the failure mode of the axle would be and what the symptoms of a failed axle would be? I had two Carlisle tires fail on the same trip a couple of years ago and that is not a good experience. I think it would be a good idea to have as large a margin of safety on the tires but not to exceed the axle limt. I would like to use the Trailmanor method for the axle limit to increase my weight capacity.
