Rim flange
wear
3-12
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.
Rim Flange wear is not a warrantable issue. Only Dura-Flange
®
wheels have a warranty on rim ange wear against sharp edges for
the 24 month warranty period.
THESE GAUGES ARE TO BE USED FOR RIM FLANGE WEAR ONLY. THEY ARE NOT A BEAD SEAT ANGLE OR DIAMETER TOOL
UNACCEPTABLE
To obtain a gauge(s) at no charge and information on free training on proper installation
and maintenance procedures, contact Alcoa Wheel Products at (800) 242-9898 or on the

STEP 1. Remove the wheel/tire assembly from the vehicle. Remove the valve core to deflate
the tire completely. Remove the tire from the wheel according to OSHA regulations, TMC
recommended practices for tire and rim safety procedures and/or the Alcoa Wheel Service
Manual.
