Tire failure - possible axle alignment problem?

[loukywells]

I had tire failure last weekend on my way home from the lake. Sheared off the center of my tire. Looking at the side view, it looks like the tire assembly/hub has shifted back. However, looking from the inside out, there does not seem to be any movement at all...viewing the rust lines. Should there be a difference in this measurement as seen in the attached pics? Could the fender hit the tire to cause this failure? I'm not familiar with this setup and would like some input.

Alright...took another look and the entire wheel sticks out and it seems that the fender cut into the tire. 1. Why would the tire be out that far? 2. How do I correct this as I just purchased and installed 2 new hubs. Can I unbolt the axle and move it forward?

How long have you owned the trailer and was tree an issue before replacing the hubs?

I'm thinking the tire is sticking out further because of an issue with that hub.

You did not post a picture of the tire on the other side, is it centered or stick our as far? From what you said I don't think so.

Looking at the pictures again where the fender would hit the tire is not the same area that failed, it would be closer to the sidewall.

I have owned the boat for two years and never had a issue. While changing the tire, I did notice that the bearings needed changing as both were shot. Both sides are identical in spacing and sticking out from the fender. I actually took the hub apart and had a trailer company take the numbers off the inner and outer bearing to make sure it was the right one...unless someone originally installed the incorrect ones. MIKE: I saw that too, however, there is a spot on the other side of the tire that it matches the fender. It looks like the corner of the fender cut into the tire (towards the outer side of the tire) and then just took the rest of the tread off. My question is: if I unbolt the axle from the frame, am I able to move it forward?

If you look at your 3rd pic you can see the centering pin in the middle of the black plate. This is a pin on the leaf spring which centers the u bolt plate.

So, no, you can't move the axle on the springs.

Can you move the fender?

The tire failure looks to me like overinflation. What Tire pressure do you run?

I agree with Kev on the centering pin that will prevent the axel from being moved. Either move or modify the fender.
