Sypping not cut all the way threw on tread
Although the tread is wearing evenly on all the tires , in production the sypping which is cut all the way threw on 98% of the knobby's ( tread lugs) on some it wore off rather quickly. Again all even , no cupping. So the manufacturer needs to do better quality control because it has happened on all but 2 out of the 5 tires.. they are kind of noisy at like 25mph to 45 mph then they quite down nicely on highway virtually no noice at all.. I currently have about 9 thousand miles on them and these are my thoughts so far..
