I think a lot of the problem stems from the specs the camper manufacturers use, not the tires themselves.

Case in point - camper in my sig is 7300# loaded. It came from factory with a gvwr of 10,000#. Has 5300# axles, and D rated tires. A well speced trailer, IMO.

I've seen newer rigs, longer, with a 10,000# gvwr. Weigh just shy of 10000# loaded. Came from factory with 4300# axles, and D rated tires. Which safety margin would you want?

Until manufactures start specing axles/tires with a significant safety margin, vs the bare minimum of what will work - we are going to continually run in to these issues.

I agree. My rig weighs 14,000 pounds and the axles are rated at 7000. I'm sure there's a safety factor engineered into the axles, but it's not adequate. The tires I had on it were speced at 3500 lbs per tire, so they're right at the maximum weight. Loading the RV a little heavy on one side would be enough to overload two of the tires.

I don't use my rig much. It's probably got less than 20,000 total miles on it and it's 12 years old. I've had a total of 6 blowouts. Three of them did more than $1100 in damage to the siding and undercarriage.
