Worn inside Tires

Yes not enough camber. Unfortunately this is probably from a bent axle. You may find a truck shop for big rigs to straighten it. But it would probably be cheaper to just replace the axle.

I have a guy who bends the axle to the correct camber. He said the axle straightened because I overloaded my 5er? I have never overloaded my 5er?

Are you towing nose high, or loading your rig in a manner to put extra weight on the rear axle? You don't say what FW you have, but some units have axles just barely adequate if wt is spread evenly.

I had my axles bent and aligned by a commercial truck/trailer repair shop about 7 years ago. The cost was $200. Alignment is still good today. Replacing the axle may be more and an alignment might still be needed.

I got the same pitch from a mobile mechanic out of Twin Falls ID. I fell for it, but I think I got ripped off. It was my tires.

So.......4 tires, 2nd axle has issues but 1st axle ok.........you think it's tires??? LOL Might have been tires in your case (you don't mention any particulars) so no idea on your circumstances. However, in the OP's case, all things being equal, it seems as though something is different between the first and second axle........I'm betting on nose high, improper loading, overloading or bent axle.

Like RAS43, I had axles straightened with good results. Can't remember how long ago, so it has been several years.

I live on a dead end street and used to turn the fiver around by backing into a vacant lot, and that involved backing over the curb. After getting the axles straightened I stopped bringing the fiver home for pre-trip loading. Tires are now wearing evenly, so I have reason to believe that backing over a curb (not once but several times) was the cause of the problem.

Verify my suspicions. I have worn tires on the rear axle tires on the inside. Very worn to a point I saw steel showing. The other tires are fine. Im guessing I don't have enough camber on the rear axle? What do you guys think?

Friends new Montana fifth did the same on two tires, axle alignment . took it to Alignment Specialists in Salt lake , great place for RV's trucks etc. He has had no more problems with his tires, its been a few years now.

Thanks for all the input. I will get two new tires for sure and then get the axles checked out. Weird how its only the rear axle tires.

Our fifth wheel came with 5100 lb axles--loaded with our normal personal possessions and fresh water, the two axles weigh 10,220 lbs. So, they were loaded right up to the limit and probably ready to bend at the slightest abuse. We upgraded to 6,000 lb axles and disc brakes. OP might want to consider upgrading to a heavier wall tube. Dexter makes 3 wall thicknesses of 3" axle tubes ranging from 5100 to 7000 lb axles. RV manufacturers are going to use the cheapest, thinnest, axle tubes rated for what they're building.
