Both Shoulder Wear

Appearance


What's Happening
The tread is not making flat contact with the highway. The outer portions of the tread are carrying most of the load because the tire is underinflated for the load.

Probable Causes
- inflation pressure and load

Corrective Action
Refer to tire manufacturer's load and inflation table for recommended inflation pressure at the speeds the tire will operate. Establish a fleet standard inflation and maintain tire inflation to fleet standard.

What to do with the tire
Because this tire has run underinflated for the load, it may have been damaged internally. Running underinflated can lead to zipper rupture, a very dangerous tire condition. Use extreme caution in handling this tire.

If tire inflation pressure is less than 80 per cent of fleet standard, deflate the tire by removing the valve core, then remove tire and wheel (or rim) assembly from vehicle. Demount tire. Ask your Kal Tire dealer to inspect the tire for evidence of run flat damage and, if none is found, to retread tire.

If tire inflation pressure is over 80 per cent of fleet standard, inflate (or deflate) tire to fleet standard and continue to run it. When worn area reaches tread wear indicators, have Kal Tire retiread tire.
