Excessive tire wear - wilsont - 07-25-2018

I purchased 8 new drive tires and have only driven 860 miles on the tires. All of the outside sidewalls of the tires both inside and outside are worn. All of the miles driven have been bobtailed. I had new torque bars installed. What could be causing this so soon?

Sidewalls are wearing? Are they aired up? Lets see some pic, how much weight, inflation psi what kinda tires?

They're wearing on the top sides of the tires. I'll go by the shop tomorrow and take pictures to upload.

860 miles?!? WOW! Did they install the torque arms properly?


RE: Excessive tire wear - smorgan87 - 07-26-2018

If theyre all doing it underinflation comes to mind.

improperly torqued bearings, bad bearings, or too much play in the torque bars can cause edge wear too.

My vote is overinflated. They’re probably fine for normal loads but bobtailing will allow the center of the tread to radius up and out making the center spin slower (largest circumference) than the outside of the tire that is held to a smaller circumference by the side wall thus making the edges spin faster and scrubbing them off. Try 85psi and see if that helps. Makes it ride a little nicer too.

I've attached pictures to the original thread. Thanks everyone!
