Currently in Ecuador. It seems that Goodride, Double Coin, and other Chinese brands are very common. They had General Tires in a department store at about $100.00 more than what I was quoted in the US for my wife's Santa Fe. I suspect that and the average monthly income being around $800.00 has something to do with it.
Goodride is super common in Canada as well.
Major brands are using Chinese factories more and more though.
Last time I looked at the tire section half the tires from major brands (Bridgestone, Firestone, Ubiroyal, Continental, etc) were made in China.
Pirelli is owned by a Chinese SOC so they are using their technology to improve production.
