6 blown tires and bent axel- help!

We have a 2013 Coachmen 292bhds. We are in our third season with it. Over the 4th weekend we blew a tire outbound and then blew a tire inbound. These were the 4th and 5th tires blown while travelling. A tire was blown before we bought the camper at our dealer. All 4 tires and the spare have been replaced. A couple of questions:
1. Could the axles have been poorly aligned at the start? (manufacturing defect?)
2. Our dealer now tells me that the right side is noticeably lower than the left and that the axle(s?) is/are bent. He suggested that when the tire blew the trailer dropped and caused the bend. Does this sound possible?
3. I bought some parts at a dealer not in our area (fixing a broken water connection that was a result of the blown tire). The repair tech told be that some dealers can test for alignment of the axles. Anyone her of this service/equipment?
4. The cost to replace both axles and get things back in order is going to be about $2000. What would you do- Repair, trade or raise a holy stink?

  • There is no way I would spend $2,000 to replace any axles. There are very few if any RV dealers that can check and adjust all aspects of wheel alignment. Start out by going to heavy duty truck/trailer suspension shop. They will have a rack for alignments. RV dealers won't have this. They can check and adjust all three aspects. Tracking, toe and camber. Next get rid of the junk ST tires you are using and get a set of LT tires or Maxxis ST tires. Nothing else is worth buying.
    The alignment check and adjustment should cost around $150-200.00, and with a new set of tires you will still be WAY under $2,000.00 and your problems will be solved.

    B.O.
  • I didn't check it on the trip. Weekend, about 150 miles from home.

    What was the tire pressure while on the trip?
  • First thing I did with our TT after getting home was take it down and have a set of Maxxis M8008 radials load range E to replace the junk ST's load range C's on my 8K TT.
  • If this isn't proof that anyone buying a new trailer should automatically upgrade the tires I don't know what is.
  • We are within recommended load for the trailer (confirmed with weigh).
    Speed 65 sometimes 70.
    Brand tire? Size 205 75r14.

  • Defective Tires
    Weight
    Tire Pressure
    Improper Blocks Under the Tires
    Axle Alignment
    Curb Strikes
    Too High of Speed

    These are the major reasons for tire failure.

    If your axle alignment was the problem you should have seen problems show up on the tire tread (scuffing or uneven wear)before a blow out.

    Go after the tire company and axle manufacturer if you weren't overloaded, speeding or anyone of the other causes above that you had control over.
  • Assuming the tires were defective, start a claim with the tire distributor. Hopefully, you saved at least one of the tires. Good luck.
  • Get it weighed first to be sure you are not the problem.
    Next set of questions,
    What speeds do you travel?
    What brand and size of tires?
    Do you check tire pressure before each trip?
  • Find a trailer alignment shop in your area, not an RV dealer. They can check the axles and advise what you need. If there is a problem with the axles, your next stop should be contacting the axle manufacturer. They may have a longer warranty than the rest of your trailer.
