Irregular wear on the surface of the rim flange is caused by abrasion from the
tire chafer and sidewall. Rim flange wear happens most often in applications
with heavy or shifting loads. If you are experiencing excessive rim flange wear
in your operation, consider using Alcoa Dura-Flange
®
aluminum wheels. These
wheels have been specially treated to significantly reduce rim flange wear.
Remove wheels from service when rim flange wear is excessive. Excessive
wear can be determined using an Alcoa approved wear gauge and procedures
detailed below. If rim flange wear becomes sharp and/or cuts the tire, contact
Alcoa for recommended maintenance procedures.
