The Coachmen 2013 spec for the 292BHDS says: base wt = 5492 lbs, 1306 lbs cargo carrying capacity which totals about 6800 lbs max on the axle for a bsae model trailer with NO options not including the base tongue weight of 740 lbs. His tires are 1760 each max at 50 psi for a total of 7040 lbs max and the tire max speed is 65 mph. Very close to his max trailer tire capacity even at a max of 65 mph. Total trailer weight max including the tongue weight of 740 lbs is approx 7500 lbs for a base NO options added trailer.
He has plenty of truck with an 11,500 lbs tow capacity and with a figure of 600 lbs of passengers in the truck still has 10,900 lbs tow capacity. His cargo weight on his truck is 600 lbs plus the 740 tongue or 1340 lbs total for a bsae model trailer and that's hundreds of lbs below his truck's cargo carrying capacity.
His problem is being at about max or over on his trailer tires and exceeding 65 mph which causes high heat buildup and tire carcass breakdown/fatigue. That's at max inflation of his trailer tires and the tire heat temp goes up with each psi under the max. Is he at max cargo carrying capacity for the trailer with eveything that was added after being built? Including any and all water etc in the tanks, batteries, tools, canned goods, TV, dishes and pans, canned liquids, clothes, etc. Every single thing/item he etc added since purchase, any option added from the base weight of the trailer reduces the cargo carrying capacity, Such as the awning, A/C, you name it.
In my opinion, his trailer is under tired and he needs to actually weight it loaded ready to leave and I'll bet he's got a surprise coming! 14" are tiny tires for a trailer that large and 1300 lbs cargo carrying capacity over a base model is a joke for a bunkhouse trailer that large. Driving higher than the max speed the tires are spected/made for is a real fast tire weakener and YES, they will blow! At min the trailer his size should have "D" range 14" tires at 65 psi or 15" tires of "D" range at 65 psi. 14" tires spin very fast at 65 mph and rotate 773 times each mile driven due to their smaller OD.
Even if they do put new axles on it and new same size tires, they'll fail again because his actual scaled weight is likely higher than the tires can handle and if he drives 70 mph they'll blow again anyway.
