I think those tires are Red Dirt Road tires made by Kunlun tire co. (China). Lot of tires are made in China. Some of the Chinese tire companies are quite large. They sell more cars in china than anywhere else ...and think about all the concrete trucks and so on? I've been to China several times and most of the cars on their roads are better than you find on USA roads. And owners are finicky about what they put on their cars. And the gov't would make the company take back a defective product too (so no incentive to "knowlingly" produce a defective product).
"Founded in 1970, Double Coin Group (Xinjiang) Kunlun tyre Co., Ltd, under supervision of the State-owned Assets Supervision and Administration Commission of Xinjiang Uygur Autonomous Region, is a joint-equity tyre company with DOUBLE COIN holding 51% shares, with registered capital of 937 million RMB, total assets up to 22 billion RMB.

I don't know anything about those specific tires or that mfgr, personally, but, in general, tire manufacturing is a global business. Most well-known mfgrs own multiple plants in different parts of the world ... and any number of plants are located outside the USA (or inside the USA). Tires are also made in Canada, Japan, Europe, SE Asia (Taiwan, Thailand, Vietnam, Korea), S. America, S Africa and some in China. I've owned a few tires which were brand-name tires which were manufacturered in China. The last set I took off my Ram were made in China by a chinese company I'd never heard of ..but a pretty large mfgr. They ran very smooth and lasted a long time. Kunlun quality control "could be" great (or not), there's no way to know since they aren't an estabished brand here. Most name-brand tire companies which have a great reputation here, the Michelins, Bridgestone, Goodyear, Pirelli, etc, have great quality control. But for the other 75% of the manufacturers ...we just have to hope they're doing the 'right thing'. I bought an inexpensive set for my plow truck a few yrs ago which were a name I'd never heard of before. But turns out the mfgr was one of the top 10 manufacturers. They were made in Vietnam and they've been a great tire so far. Not low tread either.
Generally speaking when a guy buys down-market tires there are sometimes a few compromises (not always though). Often one can look at the spec sheet there is usually less tread-depth than a similar set of more expensive name-brand (similar) tires, and a thinner side wall, or fewer plies. Could be as much as 2-3mm's lower tread. But i t's not a 100% thing, maybe yours aren't lower tread depth. Maybe the company's trying to buy market-share to gain a toehold in the USA market??. What do yours have for tread depth? A guy I know always buys the cheapest no-name tire and when you measure the tread depth, it's always pretty low ...ha ha. But here's a contridiction: Often some of the down-market no-name tires I've bought did NOT suffer rapid sidewall dry-rot like yer Michelins/Goodyears and others which use a "High Silicone" compound. They lasted a long time outdoors till they were worn out. So, if that turns out to be the case, that's a benefit right there.
Regardless, they look like a decent tread. Don't overinflate. Put some of the money you saved into regular rotations and checking balance. Once tires like that get out of balance they hop around and the wear pattern is set for life.
I hope they work out great for you. Keep us up to speed on how they run out.
