Very impressive research, Larry.
The tire industry is similar to the auto industry ...it has global orientations.
Personally, for me, it's more important what the parent company might be more than it is where the tire is manufactured. All the big tire companies have plants not only in China but in other countries as well.
I am hesitant to buy a tire from a Chinese company. However, I don't have the same reservation in buying a tire that is made by a reputable company that has a plant in China ...there's a difference.
Michelin, Goodyear, etc. all have plants in China. And remember, Michelin is a French-based company with subsidiaries all over the world.
Hankook is a South Korean company that also has a plant in China. I cited an article in another post where Hankook's plant in China is managed by the home office and has personnel from South Korea supervising the manufacturing process at the plant in China. The manufacturing techniques mirror those at their home factories and they claim the quality is the same as the tires they make in their plants in South Korea. This is similar to the claims that Michelin, Goodyear, etc. make that also have manufacturing plants in China.
On the flip side, there are Japanese tire companies that have subsidiaries in the U.S. and have a plant here. The most prominent one that makes commercial truck tires is Yokohama that is a Japanese company. It now makes just about all their commercial truck tires in their plant in Mississippi. Sumitomo is another Japanese company that has a plant here in the U..S. ...in Tonawanda New York, that makes some of their commercial truck tires at that location. Both put out excellent products in my opinion.
My favorite Tire is Toyo that is a Japanese company. It makes some of its car tires in Georgia ...but I believe many of their commercial truck tires are still made in Japan ...they too have various tire plants all over the world, however.
BTW, Bridgestone is a Japanese company. It purchased the struggling Firestone, an American company in Akron Ohio, I believe in the late 1980s. They merged the Firestone name in the 1990s to form an American subsidiary but still under the corporate umbrella of Bridgestone in Japan.
So tires, like cars, are really a global operation. We had a Subaru Outback, made by a U.S. subsidiary of a Japanese-based company, that was assembled in Indiana from majority of U.S. parts. As you know, many foreign car companies have U.S. plants in addition to Subaru ...Toyota, Nissan, Kia, Hyundai, VW, BMW, etc., etc.
