The China bomb era ended in about 2012 or so. Some folks didn't get the memo.
It is true the that performance characteristic of the high dollar tires include improved speed rating, improved compounds and more efficient tread designs. That plus the fact that they are a low volume is why they cost more.
The TT and 5ver OEM market has consumed over 2,000,000 tires annually for the last four years, add the horses, utility and large boat trailers and they have quite a track record. I doubt any of the high dollar tires have sold a million units yet.
To answer your question, I replaced my seven year old OEM tires with Tow Max tires 18,000 miles ago. I did purchase based on my local tire shop's recommendations, rather then Wal-Mart or TSC type stores.
However, in the end, facts are only facts but the choice of tires is based on your personal comfort level.
Good luck
