I have been driving on these tires for a month now and havent heard any noise until I took this long trip. We were on the highway and we heard a zzzzzzip sound then it went away. We got almost home and then heard the loud whirring sound, The sound stops if I am going 15 mph or less, and gets louder when accelerating. The only thing I can figure is that I need to replace the axle needle bearing and get new wheel bearings, Also maybe I have the wheels bearings too tight right now also.
Needless to say, the truck is staying home for about 4 more days until I get some time off of work.
