Re: Tire Markings
It is a Dealer Service Info Bulletin dated 12-8-67.This may not apply to all applications.Noted are the Chevrolet at the Flint plant,Camaro Norwood,and Chevy II Willow Run."This process was not effective at the start of production on all models,but is being introduced as sufficient quanties of marked wheels and tires become available."Take this for what it's worth,I don't know how long it lasted in production.My rims were marked with a 6/68 date and have the " bb shot".I have a assy line shot of a 70 Monte,check the intro of CBTN for the photo,with a two letter number shown on it as well.I also have a double pin stripe Goodrich with a "23" on a early 72 Chevelle.Looks like the number practice is a safe bet......
