This bulletin provides information regarding the normal tire wear condition of slight or mild tire feathering and recommended practices.

If a vehicle comes into a dealership with a concern of slight or mild feathering-type wear on the tires, review with the customer their past tire rotation history. Tires should be rotated every 8,000 to 13,000 km (5,000 to 8,000 mi) for applicable vehicles with tires where a tire rotation is possible or recommended. See Service Bulletin 05-03-10-015A for information on tire rotation for vehicles with different front/rear tire/wheel sizes. Make sure to document this type of tire wear on the Repair Order.

SOME TIRE FEATHERING IS A NORMAL PART OF TIRE WEAR AND THROUGH PROPER TIRE ROTATION AND INFLATION, THIS TIRE WEAR CAN BE MINIMIZED AND TIRE LIFE MAXIMIZED.

If the customer has not rotated the tires within the last 8,000 to 13,000 km (5,000 to 8,000 mi), a tire rotation in the modified X-pattern is necessary to clean-up the feathering, rather than placing the vehicle on the alignment machine.
