Gladiator tires are a house brand for a U.S. and Canadian tire distributor.
The problem with SOME Chinese tires is that the companies buying the tires from China are not watching to make sure Chinese factories are properly compounding, heating and molding the tires. Most if not all manufacturing is a joint venture with China controlling the factories and tire companies buying the product. Some tire companies
Virtually all tire companies in the world have a presence in China and are having tires made there. Yes even Michelin has tires made in China for the European market.
So it is not Chinese junk it is lackadaisical manufacturers. The same thing happens with many third world countries; there is no regulation or manufacturing standards so Chinese manufacturing companies are allowed to do lots of things not allowed in North America.
So not all Chinese made tires are junk it depends on how much oversight the tire company gives the manufacturer. In Michelin's case I would not hesitate to buy a Chinese made Michelin.
Would I buy a Gladiator? NO!
