Nose up creates the following: more weight on the rear axle, which not only can create tire problems, but actually increases tongue weight, since the fulcrum of the trailer weight is moved rearward.
On the other hand, the opposite is true when nose down.. Once again more weight on the front axle now, but since the fulcrum center of the trailer weight is moved forward, the tongue weight is reduced.

Sorry if you have more weight in the rear it raises the nose and decreases tongue weight, not increase. You have it backwards.

Ggardner wrote: I tow a Flagstaff 831 RLSS (31Ft.)with a GMC Sierra Denali 4 door pickup, 6 ltr. engine. I towed from Birmingham, Al. to Montanna. Approximately 500 milse from home the right front tire on the trailer blew out. I replaced it with a new tire. Approximately 600 miles later I noticed the tread on the inside of the new tire was almost worn out. I move the new worn tire to the rear. After another 700 Miles I have noticed almost no wear. I feel like something is shifting with the axles. Has anyone had this problem? Does anyone have any idea what is happening. I can't see where anything has moved on axle mounts.
I use an Equalizer Hitch and tow almost level, slightly nose down.
Trailer tongue weight is rated at 530 lbs. With propane tanks, 2 batteries and the weight of the hitch its self the weight equals around 800 lbs. Trailer weight loaded is around 7000 lbs.
Your problem sounds like a axle that is out of alignment. Is this happening to the tire that is on this location now? If it is a alignment problem it should do it to any tire placed in this location. One way to check is pick the same place on both sides of the axle and measure to the very front of the receiver. These two measurements should be within 1/8" of each other, if it is greater you need to have the axle corrected. If the new tire in that location isn't showing the same signs after 700 miles you may of gotten a bad or cheap tire. Was the replacement tire a trailer tire?
Also I see you are new to the forum. In the future you will get better response to ask your question in a new thread rather than to ask while another topic is being discussed. Any ? just PM me.

Perhaps I was not clear enough. What you say is true, of course, but you are talking about weight distribution of the trailer contents. I am not. This is regards to towing nose up or down.
This only applies to the "torque flex" axles that do not have an equalizer link. Leaf spring dual or triple axles all have them. Do you understand the purpose and function of an Equalizer link?
Torque flex axles react completely differently than leaf springs with an equalizer link.. Think about it this way: remove the front tires. Now is there more or less tongue weight? Of course there is more tongue weight. Lift the front of a trailer with no equalizer link. Are you removing weight from the front axle? Of course. Does this increase the load on the rear axle? Yes, of course.. Does this increase tongue weight? Of course.
Now remove the rear tires. What effect does this have? It puts all of the load on the fronts, and moves the balance of the weight to the rear, away from the tongue. Tongue weight decreases, of course. Now try it with all the tires on. Same effect, since there is no equalizer link to compensate.
Therefore "torque flex" axles react differently (opposite) to leaf spring axles with equalizer links in regards to towing nose up or down. Physics 101 Re-read my post.
Where do airbags play into this? I set my burb up level on the trailer frame. I got the truck to measure level. I aired the bags back up some and it looks like it is a little nose up.( the trailer) I'm sure it is, but directions said to not have bags aired up when setting up. Seems as though it pulls good though. Mike
