There's absolutely nothing wrong with Chinese tires sold in the US in our sizes. IMO.
Lurking on several RV'ing forums I've kept an eye on people reporting blow outs and other issues and it seems to me that Michelin with their sidewall cracking is the most common problem. Chinese tires are no more susceptible to blow outs than any other brand, as far as I've found. Blow outs can happen to any tire, and are usually caused by chronic low pressure, bad stem or valve, or hitting debris on the road. The numerous 'China Bomb' stories from a few years ago caused by defective tires made in China applied to smaller trailer tires. Not the big RV or truck tires we use. Those tires have been removed from the system and new regulations on imported tires were instituted back then.
I've used Roadlux, Double Coin, Michelin, Toyo, and Bridgestone and they've all given me good service except the Michelin with it's sidewall cracking, which is more 'disconcerting' than a big issue. Still running them on the rears since they came with the RV but I'll replace them this year (I stagger my tire purchases).
You have time to make a decision too, as Roadlux is available on Amazon at $215 with free shipping. Love's tire stores will balance and mount them for ~$40 each. Double Coin is available on Amazon as well.
Here's a tire size calculator to check your size against what's available to see if it's a good substitute:
