The wear looks to be what the Tire Rack blog is calling "heel-to-toe wear."

For myself, having been educated just enough in tire manufacturing when I defended some US tire companies, I prefer to stick to major brands, regardless of the location of manufacture for a specific tire.  The big brands have a vested interest in maintaining a reputation for quality that could be easily lost if they were to put their names on inferior products.  Though that is no guarantee of quality, it improves one's odds of getting tires that are safe and durable.  

That's certainly a personal choice you can make. For myself, I run Chinese 15 inch LRD's, keep them inflated properly, and am OK with it. 

I do get noticeable trailer drum heating after a couple of stops. but I didn't at first. If you're not the you might want to make a few stops or do a downhill run then compare brake temps between the tow vehicle and the trailer. After I did that the first time I realized the TV brakes were doing all the work so I bumped up the level on my brake controller and did it again and things evened out a lot better. 

You need to look deeper into this than just the manufacturer. Load capacity and proper inflation are critical. FR has at least till recently shipped rpods with 14 inch LRC tires on them that are rated just at the minimum they can be to maintain the 3500 lb axle rating (1750 lbs per tire). That is a blowout waiting to happen, especially with improperly inflated tires. I personally have no concerns about running Chinese tires, but mine are 2500 lb rated 15 inch LRD's and I check the inflation daily.

To check for tire sidewall heating (as well as bearings and brakes) an IR thermometer is handy, can be done quickly at every fuel stop. 

What is the load range of the tires? If they are load range C like my 2016 RP 179's tires, they are close to the top of their carrying capacity. That said, I used mine for several long trips before changing to load range D Carlisle tires. Goodyear Endurance load range D tires have a pretty good reputation also.

If you plan on using them, keep an eye on the tire pressure. I did and I was still told by someone that my tires looked like they were low. That is when I realized that the weight of the 179 which is similar to that of the 180 was too much for the LR-C tires. The side walls flex too much which means that heat is building up. If that can't be dissipated it will build to the point of tire failure, even if the pressure is correct. I think that is what has happened with many of these tire failures. While I have seen tire pressure monitors, I have not seen anything that is also a tire heat monitor.
