"Suspect Chinese made tires has some issue with their manufacturing
process. Am seeing so many separations from that country and must
say have from other country sourced too, but the lions share 'today'
are from China"
Correct. And just about 100% are Chinese branded tire (Because they have OEM and the largest market share). AND just about 99.5% are unsubstantiated claims since the tire was never sent in to be evaluated to the manufacturer or third party.
Most blow outs and tread separation are due to speeding, road hazards, and under inflation.
I have towed 6,500 miles in the past 7 months and have witnessed the "speeding situation" first hand.
