People complain. "I ran 100 mph while 30 lbs low on pressure and my tire blew out" or "I clipped 17 curbs because I can not drive and then spent 10 miles at speed on the shoulder". One thing is 100$ certain with complaints and that is the complainer is never at fault.
And even more exaggerations.
There have been ST tire brand recalls before. Even at the rate they have given owners problems NHTSA may not issue a recall because a blow out or run flat on a trailer isn't nearly as serious as one on our tow vehicles. Now if injuries had occurred then like the Firestone tires/Ford vehicles debacle some years back then recalls can be issued.
What most folks find out is there are better ST brands out here or tire types that eliminated their tire issues on their trailers. They/we continue driving the same roads and driving style but no more ruined tires and damaged trailer.
We had the same type comments from certain folks over on several Ford truck forums when owners started having issues with the infamous 6.0 engine. They also made exaggerated comments about those owners who had issues with them as some how it was the owners fault and not the engine.
