Comment:
I have about 40k miles on these AT3's and they have been great. They are a bit noisier than other tires but the wear life and handling along with the excellent price (I paid $170 per tire for LT265/65R17C). Based on the wear so far I should get another 40K miles out of these tires before I will need to replace them. I live in the county and have to travel gravel roads and muddy lanes in addition to paved roads. The tires work well in all cases. I rotate them every 5K miles and check air pressure regularly. I've run Goodyear Wrangles, Michelin, and Firestones and for the money you cannot beat Coopers for lite truck tires.

Comment:
The tires developed an odd wear pattern which generated a lot of vibration and noise. I thought it was my front suspension or driveline. Rotating the tires front to back helped for a while. The tire dealer told me that the tires were out of round and that was causing the odd wear pattern, vibration, and noise. Won't buy another set since this seems to be a common issue.

Comment:
I roll these tires on a 50 mile commute between Laramie and Cheyenne WY on I80. This stretch runs from 5000' to 9000' and is notorious for wind, snow, ice, more wind and hail. The A/T3 is the most stable tire I have driven on this highway; previous brands have included Goodyear, Goodrich and General. the most impressive recent event was encountering a 100 meter area of deep slush on the road at about 70mph. I attribute the control offered by the A/T3 as a major factor keeping me on the road during deceleration! Dry road noise is far less that competitors offering a similar tread pattern. Overall very pleased after 6 months.
