The link didn't work, it took me to some Altimax tires that are only rated for 44 PSI. And they were the wrong size.

Sizes, pressures, and load ranges are things that the tire industry has standardized. I've attached a comprehensive chart that has nearly every tire size in existence and the load ratings at different pressures.

For example a tire in 265/70R16 would be rated for 2,470 lbs @ 50 PSI if it were Load Range C. The same size is rated at 3,000 lbs @ 65 PSI if Load Range D, and 3,415 lbs @ 80 PSI if Load Range E. I would challenge anyone to find a tire that deviates from these standards, as to my knowledge they don't exist. See the attachment for more info.

I was too! This was done shortly after I bought the X, and I made sure it was dead empty with a full tank. I think a large part of why it's heavier in the rear because of the >300 lbs of fuel, tank, and skid plate that hangs behind the rear axle. Diesel Excursions would be different, as the engine is a good 500 lbs heavier. Of course the fuel weighs more too.

 

Fuel weight is negligible, 6-lb / gal for gasoline, 6-lb 6-oz / gal for diesel

 

Actually the attachment matches exactly what I was saying. You might want to reread it. Or perhaps you misunderstand the thread. The original comment was made that any E rated tire is rated for 3000 lbs load. This is not true. Different size tires have different load ratings. If you look at page 9 it even has a chart with the same size tires having different load ratings.


I am looking at a chart of specs for the Goodyear AT Adventure. The E rated tires have max load of anywhere from 2680# for the 215/85/16 to 3750# for the 285/75/16.

 

Okay, we're on the same page. The tire rack link you posted didn't work and I got confused.

 

~2200 lbs of concrete wood and rock leftover from a fencing project a couple months ago. Rode real nice.

 

Be very careful if you choose airbags to help with this. Read up on the internet about how airbags can promote bending the frame. This is particularly a problem when the weight is on the tongue. The airbags change the weight loading points on the frame from the two spring attaching points to the one airbag point. I've witnessed this first hand and helped straighten the frame out too! A buddy of mine has a 7.3 F250 truck (same frame as the Excursion) and he has it setup as a tow truck. He towed a mini van about 15 miles with the stock B springs and airbags and bent the frame. Granted he had about 3,000 lbs being supported by the airbags to keep the truck level. In his situation, because its a tow truck, we are putting in bigger springs, removing the airbags, and reinforcing the frame by boxing it in.

I'm not suggesting you'll bend the frame with a load inside the X with airbags but just be careful if you go the airbag route. If its something you'll be doing often, you might want to consider heavier springs or something like Super Springs, or rent/buy a trailer as others have suggested.

 

Very interesting, this isn't something I've ever heard of. It sounds plausible if taken to extremes, but these frames are REALLY tough. I had ~2,000 lbs on the tongue and another ~800 lbs in the X one time and didn't bend anything. Not saying it was a great idea for lots of reasons, as I badly overloaded the hitch.

But I did use a WD hitch, which would counteract the twisting force on the fulcrum that the air bag mount becomes. Hrmmm....

Not the same frame.

Ok ok, not exactly the same frame but for the sake of this conversation, the same.

The airbags thing is bordering on extreme but its something to consider if someone is getting near the limits of the Ford specifications.

Some folks would be really surprised just how little it takes to twist the frame. Even today there are frame twist videos of the big three and Ford doesn't do well. I really don't want to start a discussion on frame twisting. Its just an interesting video.

This isn't directly related to the airbags and frame bending but its interesting none-the-less.

 

That makes me sad I wanted the Ford to be better... It still is in every other way
