I personally feel that folks put way to much thought into the name on the tire. 99.9% of the tires are made by the same manufacturers onshore and off shore.
Basically they just change the MOLDS which have the manufacturer name to be sold in it.
I just replaced my Carlisles which had a manufacturer date of 7yrs (I had them for 6 yrs). The reason as to why I replaced them? Bad VALVE stems!
Thats right, I had one valve stem over winter BROKE OFF.
I decided since one stem broke the others would follow. Since I was needing to replace the stems it made sense to put new rubber on at the same time.
A search of the Internet revealed that there was a bad batch of valve stems sold which lined up with the time frame I had the new tires mounted.
There is a good chance that there is STILL bad valve stems being installed yet TODAY since there was millions of stems manufactured before the recall and many shops may have never seen the recall.
Chances are many people have had a bad valve stem and blamed the TIRE MANUFACTURER for the tire blowing out.
Simply put if the valve stem breaks it is the same result as a supposed "defective" tire, basically shredding the tire and trailer. The problem is the process of the tire shredding damages any evidence of the broken valve stem. Then EVERYONE on the forum jumps to conclusions and automatically blames the maker of the tire.
