Flat Spot On Tires - Please Explain

Could someone explain what he did in order to cause this? The comments are full of insults and I'm not able to determine exactly what he did in order to ruin his tires overnight.

If there trailer tires, did he set his trailer brakes I spend the night there a 2 days a go it was all snow and ice. If he set his brakes could have frozzen the shoes to the drums and driving on the ice he would not have noticed it that easly. But those look like drive tires to me so maybe the same thing, but I have never Hurd of that happing to drive Axel before. Maybe a non powered Axel?

Looks to me like his breaks froze and he drug his tires. Very probable staying in OR overnight.

There are only 2 things that cause this. One is locking up the brakes in an emergency stop situation. The second and most common is frozen brakes. This looks to be the rear axle on the tractor that is not engaged unless you flip on the power divider. Oops the last thing is a mechanical failure on the brakes.

Drug his tires, tires were not moving, and skidded off all the rubber. tires are shot need replaced. Could have been frozen and not released, from driving in snow and slush then parking in below freezing temps. Could also be a frozen or kinked airline. Basically the spring brakes need air pressure to release them from parking mode, pushing the springs back. So either air was not getting to the brake chamber, or air got there but the pushrod and S-cam assembly was frozen, or the shoes were frozen to the drums. All of which cause a no-turn situation. These are either his engage only drive axle or his trailer tires since you would really know it if your normal drive axle had a frozen brake somewhere.

If you ever are "struggling to move forward" that's a time you should GOAL!

Looks like his breaks froze or he forgot to release the brakes That or he locked them up I'm willing to bet they were frozen though saw this a lot back in North Dakota in the oilfields.

Hey sometimes you have to do what it takes to get the load there.

Including driving with defective equipment, am I right?

On another note, I spent last night in Chemult, OR. The place was iced up, especially the parking lot, its no wonder his tires locked up.

I just came from (near) Portland, OR. I agree that it is pretty bad up there, and in Yakima, WA.
