Uneven Tire wear

I have not noticed any uneven tire wear on mine. But I did notice that when I am traveling down the road I have negative camber on the wheels. I know most trailer axels have postive camber on them and I know that when standing still mine has either slightly positive or 0 camber on it. I would have to get out a laser and be on a level pad to know for sure. I think that the wind must put a downforce on the axle causing the negative camber. It does not apear to be enough to effect tire wear much on mine though. 

If the outter edge of the tire is worn in a short area & not in the rest it leads me to believe that the tire has a broken belt. If it is worn in more than one area on the edge(scalloping), that sounds like balance.
BTW, in my 30 years of doing alignments for a living, tire wear on the outside edge is caused by too much Toe In, or too much positive camber. If the tires were wearing on the inside & outside edges equally, the cause would be under inflation. Another cause of scalloping could be the fact that these trailers do not have shock absorbers to hold the tire in constant contact with the road.
I could go all Techntrek on you about tire construction, alignment settings, inflation, balancing. But I won't. I've given the basics.
That all said, I noticed on our pod, after 5,000+ miles that the (balanced) tires are showing a little bit of outter edge tire wear. Very slight. I study these things... I chalk it up to being heavily loaded for the tire rating & the cornering forces applied there upon.
When in the mountains of Colorado, I found that I could go around curves at about 5-10 mph above the posted curve speeds.

I don't believe we are looking at a broken belt condition in the OP pictures considering both sides are wearing unevenly about the same although wear pattern is similar.

Good point regarding the lack or "real" shocks and cornering loads.Very likely a contributing factor to everyone's seemingly different wear patterns.

A broken belt is a serious and dangerous condition.Quite obvious when it happens with vibrations and sometimes instant failure with no time to react.A real problem when the industry was making the transition to steel belted radials during the 70's that plagued every tire manufacturer.The steel to rubber bonding technolgy was in it's infancy and was a real problem.Today most steel radials have a transverse nylon layer "over" the belts to eliminate separation,Michelin was the first to use this method.

Even later tires had problems,we all remember the Firestone ATX on the Ford Explorers

Today we rarely see belt problems unless the tire was run serverly under inflated for a long period of time.

Interesting info on the Fords Explorer.Like everything else the media runs wild with it....

I went for a test drive yesterday with the Load range "D" tires and didn't notice the Pod running any rougher.

The side walls still flex a bit,just not as much as before with the stock tires.One thing I did notice was that the suspension was moving more then before,actually absorbing some road irregularities since the tires themselves were not bouncing as much.I could actually see the trailing arm moving in my rear view mirror.
