Just bought some AT51s (285/75R16) because of good reviews and price. I ordered them on-line from Tirebuyer for $610 shipped for the set and had them delivered to the local Firestone dealer to install at a quoted price of $78, and upgraded $22 for lifetime rotation and balance. And FYI, I am coming from Dueler AT REVO2s in same size that I was very happy with-- lasted 70K miles, low noise, and good snow, wet and gravel performance.
Now that I have ~2000 mi on the At51s, I am already regretting it due to their droning noise. They're not real loud per se, but have a this low, buzzy hum at almost any speed that is really annoying, kind of like a bad, white-noise soundtrack. I guess I should have listened to one of the tire shops I visited in Boise told me that they were loud and recommended I go with Hankook Dynapro AT-M. The dealer said he put some AT51s on his dad's F150, and they swapped them for the Hankooks the next day because of noise. Most reviews say their are pretty quiet. Maybe I'm just sensitive to their frequency" Oh, and I'm now also experiencing extra noise in the form of 1-2 Hz harmonic at greater than 60 mph. I'm going to have them rebalanced and see what happens. Could also be my spindles or bearing (or?) as I was getting some Birfield vibration due to lack of grease in the knuckles.
