Heel & Toe Wear

Appearance


What's Happening
The trailing portion of the lugs are scuffing like a rubber eraser. The lugs are distorting during acceleration or during operation so they are not making flat contact with the highway.

Probable Causes
- mismatched duals
- inconsistent dual inflation (10 psi or greater)
- torque stress
- tread design/tire design

Corrective Action
Match duals by tire brand, size and series (difference no more than 1/4" in overall diameter). Inflate tires to fleet standard. If the tractor has a single drive axle, torque stress may be unavoidable. Also, in some applications, heel/toe wear may routinely develop on certain tread types. The only solution may be a tread design with larger, more stable tread elements or solid outer ribs.

What to do with the tire
Continue to run tire. When worn area reaches tread wear indicators, have Kal Tire retread the tire. To obtain maximum mileage from the tread, rotate the tire to a different drive wheel position.
