The ALCOA Rim Flange Wear Gauge is used to assess whether a wheel should be withdrawn from service due to excessive wear on the rim flange. This component plays a vital role in supporting the tire sidewall and bead, and the gauge ensures that the material remaining is adequate for this purpose.

Rim flange wear, caused by road debris, is a common issue for vehicles carrying heavy or shifting loads, or those with underinflated/overloaded tires. This problem arises when abrasive substances rub between the wheel flange and the tire, gradually wearing down the flange.

The wheel flange is essential for maintaining the tire's integrity and preventing tires from detaching from the wheel. Regular inspections and maintenance are crucial to preserve this part of the wheel, thus ensuring maximum safety and minimizing costs.

Without proper maintenance, flange wear can cause premature wear of tires and therefore unnecessary and costly replacements.
