Tire Wear

[Eagle Man]

We have a 3400RL with a little over 6k on it. The right front tire is wearing evenly, but the other three tires all show wear on the inside of the tires. Took it to the dealer, and he said the axles, tires, etc are all aligned as they should be. He has a call into Keystone to talk to their tire/axle expert. Any suggestions from the group would be appreciated. Thanks.

This just doesn't sound right depending on what your indicating "wear" to mean. If three tires show inside wear it would suggest camber out and is due to possible axle bow. Have you looked down from under the king pin to see if the axles look parallel to the ground? If they sag (low in center) then its possible this loads the inside edge of the tires.
The right front tire sounds like it has a belt separation and needs someone to inspect closely looking for a band that shows on sidewall as an indentation going in the radius...from center to tread. Do detailed inspection...may not show on outboard...so look inside as well.
Let us know how you do...

Sorry if I did not fully explain the problem, it has nothing to do with the side walls, just the tread. By 'wear' I mean the tread shows more wear (less tread remaining) on the inside tread of the three tires mentioned than on the outside tread. The right front looks normal, with all the tread wearing evenly. The dealer did all the axle/tire checks while he had the rig and said all were okay. Have not heard from him/Keystone yet, but something is definitely wrong.

Tire wear was the second reason I went to MOR/ryde Individual Suspension axles. It allows for wheel alignment just like wheel alignments on cars and trucks. First reason was to help keep things from jumping around inside the rig.

Is that different from the Mor/ryde suspension system that comes on the RV as standard?

Eagle Man I heard ya. I still would do my own gander down under to just eye ball them there axles. Camber can do exactly that to the outside as it loads that outside edge and may be even wear all the way around. The one tire that is odd-ball of group needs to be further investigated for another complication...like a failed band/weave internal construction and often shows as dimple on outer shell. This failure can happen from hitting really bad road condition...like (snow sharks...big ugly pot hole) and such.

Yes, there's quite a bit of difference. The individual suspension system allows each wheel to move up and down independently from each other. In other words, when you ride over a bump, the front wheel goes up and over, followed by the second wheel that goes up and over. This is as opposed to the suspension systems mounted on keaf springs to the chassis. If you go to www.morryde.com you will see an actual demonstration of this action.

Please be aware that I in now way am associated with MOR/ryde. I just like the product.

I had the same uneven tire wear that you are describing. Inside wear is caused by axles that have lost their camber. The axles were made with an upward bow in center them that keeps the wheel flat on the pavement. This bow creates the camber that makes the tires match up with the crown in the road. The also lets the axles flex with the load on the trailer as it goes over bumps in the road. Do a search on technical problems and you can see my story.
