Everyone that has issues with equipment and they feel it's a common or a safety issue should file a complaint with the NHTSA
I looked and there are 197 complaints against Carlisle tires. Some of those are not ST tires but most are. Please when filing a complaint, be precise and provide all pertinent info. I saw a lot of complaints that gave almost no details.
If they get enough complaints they may start an investigation. My feeling is that it's going to take a lot of complaints because though it's dangerous and a real safety issue. People are not getting injured and their not on passenger vehicles. I don't agree with this but injuries get the most attention.
My Grand Surveyor came with Goodyear Marathons on it so FR does use other tires.
