Also just because a tire is supposed to be made in China, Mexico, USA doesn't mean it really is!
My dad worked @ General Tire in Mayfield, KY for many yrs.
Then in 2002 or 2003 some idiot politician put the cost of clean up of their "dump site" to be included in the "Mega-Fund" bill and the parent company of General known as Continental Tire (a German owned company) decided it was time to get rid of that plant.
In-spite of all the union's, employees, and local community efforts to keep the plant open they were told point blank @ one point "You couldn't pay us to keep this plant open!"
Then they shipped the equipment down to Mexico (they already had the plant in Mexico), and started using it to produce tires.
Next thing you know they are getting many many complaint's of tires made in Mayfield. Upon checking they found they were getting more complaints than the actual # of tires made the last week of production in Mayfield and investigated farther.
What they found was the equipment in Mexico still had the Mayfield plants last id & date code still in it and still making tires 8 months after it was put into production in Mexico.
They recalled tons of tires and shipped them to Mayfield to be checked and tested at the closed plant. (I personally saw 40-50 truckloads show up one day in about 7 hrs as I went by both ways that far apart!)
End results were said to be that 95% of the tires recalled were made over the 8 month period the equipment was in Mexico and had various defects!
Also during their investigation they found some bad tires showing to have been made in other plants such as Mt. Vernon, IL ~ Akron & Bryan, OH, ~ Charlotte, NC ~ and even Barrie, ONT, CA were actually came out of Mexico where those plants had retired equipment that had ended up in Mexico and was used with the old location and dates codes still in them.
I ain't say'n just because it's made in Mexico it's bad.
Nor am I saying that the plants in Mexico are the only places this could be happening!
My guess is that any old equipment going into any plant (new or old) in any place of questionable ethics could result in this happening.
I know in Mayfield where the employees were permanently laid off without any hope of rehire they could care less where the equipment ended up or how it was used. But I would like to think it should be mandatory that any equipment leaving any plant have the plant code removed so that who ever used it next would have to put their own in!
