Need thoughts. Have owned a lightly used 2005 DRV Mobile Suites 5th wheel since 2012. Fabulous rig. Replaced original 7 yr old Goodyear GST's when purchased in 2012 with the same tires, that looked great by the way, and no problems with our new ones and very even wear. As a precaution (6 yrs later), we replaced them with same tires in 2018. About the same time, we also replaced the original Dexter Hub and Drum Assembly 7000 lb Nev-R-Lube Axles, Dexter Nev-R-Adjust Electric Trailer Brake Assemblies, and Dexter Shock Absorbers.

After 16 mos and ~ 10-15k miles, we have now discovered that ALL 4 of our Goodyear GST's have very significant wear on the inside of the tires. What????? Never a problem in 7 yrs?!?

Best I can figure, either:
1) hubs/drums were not properly installed,
2) hubs/drums were defective from factory, or
3) axles have failed or been damaged

Since we've owned this rig now for 7 yrs, I seriously doubt we've overloaded it weight-wise as nothing much has change since.

Appreciate any thoughts you all may have. Thanks!

Seems like the simplest answer is you didn’t get the axles you paid for and they are overloaded or they are cambered axles and were installed upside down. Not much else could explain wear on all 4 tires.

mobile suites with 7K axles? interesting.

I'd get on the phone with dexter and talk. and then get an alignment.

If you are keeping the rig you might want to get with mor ryde and do their IS system...a quick $7K but disc brakes.

Had new dexter axles installed a couple of years ago while on a extended trip to Alberta, Canada. Long story about that but jumping ahead, when we got home my son noticed wear on the inside of the XPS Ribs I had on the axles. Had the wheels aligned at a shop here where we live. It's a process I watched and when the guy used a sledge hammer to more or less bend the axles while watching the electronic setup he had, I was kind of taken aback but apparently that's how it's done. New tires(XPS Ribs) have been installed this year in May because the old tires aged out but didn't wear out. Have done 3 trips this summer and no sign of wear. Next summer we will be heading out west again.

does it look something like this - [image]

If so, My Goodyear G614's looked like that as well.. I went to Goodyear and inquired about the issue.. After some looking the manager came up with what they called "Shoulder Step" and deemed it normal for the tire.

He even showed me a picture on his computer that looked exactly like my tires.

I trust Goodyear, but did not trust that tire wear so I upgraded my stuff to 17.5 G114's and never looked back.

Have you looked at the tag on your axles? If it's a 36' DRV the axles should be 8K, even a 32' should be. They are simply HEAVY rigs!!! My 36' weighed well over 19k.

What that is is the width of the tread is too wide for the steel belts, so the outer portion of the tread is not as supported as the rest, so it wears faster. It is aggravated by frequent and hard cornering. Nothing to be concerned about except for the appearance. Ultimately it means that Goodyear's design engineers didn't do a great job in the design process.

It's likely something has caused an out of alignment issue. I take mine to an axle shop every two years for an alignment check and adjustment if needed.
