Very interesting thread for me since I found a right rear wore down almost to the cord on the inside edge, in tampa on my way to our florida lot. It had been reading about 8 degrees hotter than the others according to tpms. Had to limp to a tire shop, then they put a 10 ply on instead of a 12 ply, I gave up and told them to put the spare tire on the fancy wheel and put their under rated tire on my spare wheel and left.

I've only put about 150 miles on the spare and it looks ok so far.

Only put around 15000 miles total on the fifth wheel since we bought it. 1100 of it was this week's trip to florida.

Take it to a place that can align and work on trucks. Have them check your bushings in your shackles and springs. If they are bad, have them replace them and have them align your axles.

Put a couple thousand miles on them and then left for an 8,500 trip. About 7,000 miles in I noticed that all 4 tires were very worn on the inside. So much so that I stopped at Les Schwab in Toolee, Utah to have them flip all 4 tires so the worn edge was on the outside. They were nice enough to let us boondock under their carport for the night.

When we got home I got into it. First, the rig came with 6,000 pound axles but the springs were rated 2,500 pounds. I swapped out the springs to 3,000 pound rating.

You can check out alignment with an 8 foot straight edge. Place it horizontally along the center of the tires. The sides of both tires should be touching the straight edge at all 4 spots. If not, axles are bent. My left side was fine, but both tires on the right side were off. If you Google "straighten trailer axle" you'll find videos of guys using a chain and hydraulic bottle jacks to straighten bent axles. I spent $32 for a 30 ton bottle jack at Harbor Freight. Followed the videos and aligned myself. You can check vertical alignment using a level, they should all be slightly "bubble out".

Leaving on another cross country trip next month. Put on new tires and am going to keep an eye on tire wear using a tire depth gauge.
UPDATE 1/3/2020: I have put over 12,000 miles on rig since spring upgrade and hillbilly alignment. Tires look almost new...no unusual wear patterns. Problem solved!

If your going to continue to pull 6500 miles a year bite the bullet and go with MorRyde independent suspension and disc brakes.
Several have gone that route and love it.

That should have read that I've only pulled this trailer 1500 miles, not 15000.

Checked axles with a 6 ft straightedge and a level. Bad tire is way out both up and down and side to side with the other tire on that side.

The other side checks good.

That is a heavy trailer if loaded to capacity of 16,600 pounds. Makes me wonder what axles were supplied under it. 7K, 3" diameter tubing are supposed to be normal OEM but may be too light duty

Assuming the axles are adequate, sounds like the spindle is bent on that side. A truck spring shop might be able to fix.

This sure sounds like the classic bent stub axle symptom. Likely due to hitting a curb, pothole, or other obstacle. Not an axle that has lost its camber.

My dealer gave me the phone number of the dexter warranty dept. I called and they emailed me a warranty form which I filled out this morning. Warranty guy said they don't bend axles, it will be a replacement.

I think they're going to replace the axle and the tire.

With the poor condition of the interstate highways, it’s a miracle our trailers can hold an alignment. I thought I-5 in California was bad, until I drove I-40 thru AZ and NM last week.

That's all well and good, however if the alignment is not at least checked you may have continued issues. Simply replacing an axle may not correct the issue.

I was talking to a trailer maintenance guy the other day, complaining about the deplorable condition of the highways, and he said the highways leading out of Goshen (or is it Elkheart, whatever) Indiana are the worst in the nation. These trailers arrive at the dealers most likely out of alignment, and most dealers don’t have alignment facilities to even check alignment, let alone fix alignment. I agree with the statement above that the axles provided are the bare minimum required, with little or no reserve capacity. Potholes and low-speed (I.e. parking lot) contact with a curb should not be knocking these out of alignment. My last alignment cost me $200 per wheel (the only shop around who would do the job, and priced accordingly). I am extremely careful about contacting curbs, but sometimes it’s unavoidable.
