here is photo. Both tag tires look the same. Wear is even and clearly excessive. The other six tires are fine and show hardly any wear.

I have put less than 5k miles on her so far and the tire were new almost 3yrs ago. Just a couple months beyond production date.

I've never dealt with tag axle before so your ideas will help.

The suggestions have me pondering a suspension issue? Already got the tip to check the bearings ASAP. THANKS!

Run it over a scale.

If I remember correctly, the 36' F53 chassis I once owned, the tag axle was designed to carry a max of 2500lbs.

I will run scales again just to double check. This wear happened in less than 500mi as prior to that there were wearing fine. I haven't added more weight either. Still, like idea of reweighing.

I have to replace the bushings with urethane as originals are toast. Haven't been in a hurry as i haven't taken n her out of town in over a year...well a 20mi round-trip a few times. These are crappy Thunderer Commercial tires but... meh i just confused. arrrrggghhhh! hehe

I have the Ford F53 Owners Manual so I'll confirm details there are well. I just know i don't want to get out on a trip until i figure this out..

tackling the bushings tomorrow (Saturday). Have to figure thus out ASAP. Plus under my beastie it's harder to find and yell at me fir lacking the ability to extinguish 12 fires at once.

I've read all manner of suggestions on the web and here. I now get there is no magic idea as it can easily be any of 47-many things. Have to start somewhere so bushings it is. I think I'll pull the wheels too and have a mechanic buddy stop by and give bearings a once over. note to self buy beer for buddy.

i just think i remember a fact i was told about for our F53 chassis. The tag isn't factory but added by manufacturer. Is that correct? it would explain why i can't seem to find reference to a tag in my Ford F53 Service Guide?

You are correct. The motorhome builder adds the tag and the brakes for the tag. That is why there are so many different types. As a service manager for 15 years, I can say from experience, you have #1 too much load on the tag. #2 dragging brakes on the tag. Forget the turning problem. I have never seen or heard of a gas tag that lifts the tag when turning. Many diesels do, but not Gas.
