Local dealer says stay away from new Maxxis tires??

Haven't heard anything negative lately about Maxxis ST tires. Already have four seasons on current set of Maxxis tires and I estimate going a couple of more before getting another set. I guess any tire manufacturer can have a bad batch make it to the marketplace, will wait to see if newer Maxxis ST tires begin to indicate a higher failure rate compared to years past. Hopefully not as I have grown dependent upon their durability, effectively serving our needs on our current 32' 9K# TT.
