That's what I did after an alignment. If yours are like mine, you can't just swap positions due to wheel dish and it is impossible to clean up the opposite sides of the wheels, as both the steer and tag wheels would need to be flipped. I had to have the tires dismounted and remounted keeping the wheels in their original positions. Just more work.

My tire wear is the same as yours,but at 23k.I just came from the alignment shop and the Toe-in was way way out of adj. Post #23 nailed it. It also made the handling of the Motorhome a lot better.

OK and what is your measured load on each tire when loaded for normal travel, Tire size and Load Range info too please.

Actually, one of the good things about the Ford chassis is the solid front axle will hold it's alignment unless the tie rod gets bent or parts wear out. If everything stays tight, alignment is 'one and done'.

Except what you get is a very large "Camber Curve" where the camber goes through an extreme range Positive to Negative. This can lead to high shoulder wear.

If someone thinks wear is due to low inflation I would ask what is your measured load on each tire position vs the Load & Inflation table stated inflation needed?

My owners manual says to run only the pressure on the Federal Weight sticker, which is what I do. The ride is great, probably due more to weight and length than the tire pressure.
I'm amazed at how cool the tires are when I check them, much cooler than my last rig running the pressure from the Michelin charts.

He has a solid axle. The only thing that changes camber is bending it (which voids the warranty).

I had a solid front axel adjusted (bent) to adjust the camber and eliminate the tire wear. How can this void a warranty and how would anyone know? And only a 1-year warranty anyway?

Every truck axle manufacturer has this policy. I have been told that the beam is not made to bend. I know that many alignment shops do this but it's frowned on by the axle engineers.
Over 30+ years I maintained hundreds of Class 8 trucks. I never bent an axle. OTOH, it's your RV, feel free to do whatever. I'm just giving you a heads-up.

Yes, that's what the axel maker said to me.
My frame and alignment guy said bending is for fixing a flaw. I could either wear out steer tires every few 1000 or have it bent. So it was bent, and tire wear was gone.

Just think about how many heated and bent axles are out there. Engineers are probably worried about the heat taking the strength out of the steel. Or them taking the hit for something they did not recommend. I can see how this would be the case.

Not heated! Simply bent. It WORKED. I won!
Let the engs take the heat. They earned it.
