I have some feathering on my tires (see signature). The fronts have it, the tears don't. My alignment as far as I know is good.

My previous truck also had feathering. They were duratracs and again the siping was the issue.

Included are pics, they look like they are wearing evenly but it's only been 3k kms.





I do have a on ramp at a higher speed and I thought that might have been contributing to the duras so I've been avoiding it and using the service roads at less speed but I still am getting it.

I realize any tire issues such as cupping, feathering, uneven wear can all be traced back to the alignment and wear and tear of parts. My truck has 51k kms (30k miles). The bilstiens are my only modification to my suspension.

I also checked my tires pressure. Driver side was 38, passenger side was 36. I added to make them even.

 

If that's the outside edge your truck is toed in too much, if it's the inner edge, it's toed out too much.

Alignment will fix that.

Ok, thanks. I'll bring it in.
