The trailer sure didn't gain weight by itself, so it was "self inflicted".

Being overloaded on a tire yes, but not having enough rubber to carry the axles - no.

As well, the flattened axles happened (per pictures) last year before I was loaded like I am now.

And, on edit- I don't consider the replacement wheels and/or tires to be FR's "fault". This was an upgrade that I chose to do. BUT, the differences in capacity bug me (where the tires can't support the axles).

I don't recall seeing anything about a lesser GAWR.

That's a serious error by Forest River and should be reported to them or NHTSA or both.

The trailer in this thread should have had triple axles to achieve more reasonable tire loading but that would have cost money.

Thanks for "lingo" correction. I mean dual wheels on two axles(as they do on heavy equipment trailers). Wouldn't that fix the 2 axle trailer problems? They run them at max...we know that is bad all around. Then maybe you wouldn't need q rated tires for a d/e availability.

"To identify the proper inflation pressure for a tire, please consult the vehicle’s Tire Information Placard – not the sidewall markings on the tire. Proper tire inflation is determined by the vehicle manufacturer only."

Why would a major tire manufacturer say that if it wasn't true?

After market replacement tires with different sizes and designs than the OE tires will naturally have different recommended inflation pressures set by a tire installer. But, the OE tires are still the benchmark for replacement tires because the replacements must have equal or greater load capacities when compared to the OE tires. In other words, an OE tire's recommended inflation pressure provides 3000# of load capacity according to the tire placard recommended inflation pressure. Replacements must provide, at a minimum, that same load capacity by inflation.

Adjustment for inflation pressures above the recommended amount is OK up to the figure for the maximum allowed load displayed on the tire sidewall.

Too mush space inside the TT would be lost if weel wells were twice as wide.
