Had literally 40 Coopers on different trucks, trailers, spouses Astro Van in the 90's. I have yet to have a blow out due to a case issue. Micheblows on the other hand. Wish I would have put the AT3 on my truck last summer vs the GY Duratrac. Nothing wrong with the GY's. BUT the AT3 is quieter on the freeway etc. traction snow wise in maybe a bit less to more depending upon Type and style of snow/slush you are in. Utah should not be an issue with AT3's.
I too found the BFG AT to be the worst snow tire I've had. Both sons are running AT3's too. Probably because I've been buying them since the early 90's.
Schwab is selling a private brand Salun tire. Seen a bunch running around the Seattle area. Thought about that option last summer too.
