tire problem

I just now zoomed in and saw what you meant by eraser there is nothing wrong it's just from turning
Check again in a few thousand and make sure it is wearing evenly my tires have those exact same marks and they been on for 60000.

 

That’s normal if you had weird grooves that’s a different story. That little edge helps the rest of the tread on steer tires last longer. I forget why but my tire vendor mentioned it awhile back.
There’s a few different things that cause abnormal tire wear. All related to steering components.

 

Low pressure will cause them to wear on outside, high pressure wear in middle. Might want to get front end checked. Maybe just new freshly made tires, soft rubber. Nothing wrong with tires, yet anyways. Condition of old tires should tell you more about alignment.

 

mite need to true the tire

 

I had the same wear on my last set. The first picture is after 2,000 miles. I am running 11R22.5 H rates tires. I stated out running 115psi, but immediately started running 125 psi. That weird wear stopped after about 4,000 miles and I was able to run those tires to 199,999 miles.
