First point - I've been running the Toyo AT2's on my new truck. We've had a substantial amount of snow here in Colorado since March, and from that standpoint (fresh powder/ice/slush), these things have performed flawlessly. I've been driving in snow for many years, and these felt rock solid. Light trails (mud/sand/rocks) so far have been super tight. My only negative thus far, is traction from a start on wet pavement (fresh rain, puddles, etc). I would say PART of that is due to the fact that this is my first go around with a naturally aspirated hemi with a lot of gumption off the line. If I take it slow, they do fine. On the highway (in rainstorms), they've performed well, no hydroplaning at all yet.
Second point - The reason I switched (was running Hankook Dynapros and Wranglers on my last F150), was about three years ago, some guys at my office (7 in total) all made the switch. We're all Auto Brokers, and part of what we do is aftermarket setups for our clients, helping with mechanical, buying tires, etc etc. Three guys here at the office in particular, are truck nuts. ALL of them have 30 foot toy haulers, do some hefty off-roading, and travel often. They've been running AT2's, and switching all of their clients over as well. Their main reasons for switching: Tread Life (50-60k easily with proper rotation), tire noise (very quiet for a fairly aggressive A/T), Look, and value. I have since begun switching all of MY clients to them. No complaints from anyone. Everyone who's truck I've put them on loves them. At least 15 or 20 peeps in the last few years, no issues (and people WILL call me when they have problems).
Per the guys in my office with towing/offroading experience - rock solid, track well, no "squirming", wear well, one puncture between the three of them over the years. MOSTLY hard pack/rock trails here, some sand areas. No issues towing. Excellent performance in snow/mud. Tread life has been consistently loooooong.
Anywho, I've only personally had them on my rig for the last 3 months, but I'm a huge fan. The road noise (compared to some KO2's that my buddy is running on his F150) is much quieter, if that matters. Highly recommended.
EDIT: Airing down - forgot to ask them about that aspect
