Fifth Wheel tire blow outs.

Easy enough to weigh each axle at a truck scale and see if you need to move some weight around in the 5er to equalize. Maybe you should be nose up and maybe nose down, just depends on your particular set up and weight locations.

I am not so sure the wind on the front makes a difference at the axles and if it does then on which axle. It could be pushing down or lifting up on the front. Hard to say. If a wing is analogous to the front, then wind lifts the front up-flat bottom rounded top-however wind hitting the top portion of the front should force it down. I am sure someone is a wind tunnel expert and will have an informed opinion. May depend on the shape of the cab in front of the 5er and where the wind goes once it is over the cab.

A guy passed me today pulling a big 5er. I was in my car on the interstate going 78 MPH. He had to have been going 85, at least. I had about another 15 miles to go before my exit. I thought I’d see him on side of the road with a blowout, but I didn’t. He must’ve had good tires and a pocket full of money for fuel.

Love that theory!

Way too many to a 5er nose high! It is either too much trouble, or too much money to bring it level. Towing nose high loads the rear axle more than the front, the equalizer can only compensate for so much.

You really want your 5er to tow as level as possible. Getting to level could be as simple as adjusting the pin box or hitch height, or it might require flipping the axles, or building a sub-frame.

I was lucky, pin box adjustment, then installed Correct Track system for 2" at axles and we are level.

All, or any RV can be either balanced or one side heavy. It all depends on design. A properly designed RV should be pretty well balanced. Shredded tires normally is caused by,
1, wrong tires,
2, cheap ST tires run above rated speed,
3, nails, screws, etc. In other words a flat tire,
4, poorly maintained tires,
5, out dated tires,
And the list can go on. Bottom line, there is no way to determine what caused the tire failure.

.. and #4 above includes tires without proper air pressure. Check your tires once in awhile, you'll save yourself some issues down the road.
