I was told the same when talking to GY after my 614 blew a fist sized hole in the sidewall. However, GY did send me a check for half the price of the tire that blew out even though the cause was undetermined. That helped as my rig is only two years old and has 614s on it.
Now about the Sailun S637s being made in China. Yes they are, but they are the only Chinese tire that meets BOTH the US import and export specs. Most only meet the import as oddly as it sounds. That being said, make sure you have the clearance between the tires you will need as one size of the Sailuns are taller than the other and may decrease the gap between the tires for those that use X-chocks. Most people do not realize that Sailun S637s now come in two sizes. 235/80/16 and 235/85/16..
Attached is the load chart of you would like to see them.
