tire manufacturing is a pretty mature industry, there are no hidden skills to making tires, and cars need tires no matter the country.
That said, if you can ship a tire from Thailand to Texas and sell it for 90 dollars, it definitely has to be pretty basic, or perhaps corners were cut that are unavailable down at the Goodyear plant. It is definitely not some kind of extraordinary rubber compound tire.
In my opinion, I would only consider buying such a tire from a local brick and mortar store, because if you get a defective product, dis mounting and the time to arrange a shipping solution will cancel whatever price advantage makes the deal attractive.
I knew a woman the actually got four new defective tires for her truck, a situation I would have thought impossible. I don't want to slander the company because I can't recall the brand, but they were a good second tier name brand company, like a Cooper tire.
Her truck didn't ride right, she went back to the shop, and the manger identified all four tires as defective, and replaced them all free of charge. I saw the tires and the sidewalls looked odd, they had a visual imperfection instead of being smooth.
Personally I see tire brand names I never heard of on really big rims, probably for lack of other choices, because rims like those and the modified vehicles running them are not cheap, and they seem to be working ok. But I certainly wouldn't mess with them with normal sized rims.
Perhaps if you asked around at a tire shop that handles dub wheels, they could give you info on Thailand or general advice on way off brand tires.
Myself, I consider tires a safety component first, because I live in an intense traffic environment , but also realize they are the primary mechanism that will effect my enjoyment of the car. I am fortunate that I can afford high line tires for my vette, but instead of the usual michelins, I went with Goodyear, said in some reviews to be a touch sportier, although for my needs I won't need top performance, except in case of an emergency, where an once of prevention is worth a pound of cure.
