Service bulletin CALFTLWS000-01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Freightliner 108SD/114SD, Coronado, New Cascadia, and Business Class M2 vehicles and Western Star 4700 and 4900 vehicles equipped with a certain tire rating have the wrong Component GWR label.
