I've at the Toyos AT3's for about 2 months now. Here is what I've noticed:
Tires ride slightly stiffer than stock tires. They take SOME of the "CADILLAC" ride out, but not to the point that it is disappointing. I've not noticed any more noise from them, as I suffer a little bit of tinnitus (I'm over 50 lemme lone) I've not had the chance to take them back in the thick dirty dirt roads, I've only have highway miles on them and they are some pretty good tires, with no complaints. I've also noticed less body roll while turning corners, the truck feels slightly more planted, as there is less sidewall flex.
Wet conditions, they feel really solid. I've not had any incidents when they didn't feel planted/solid on wet surfaces.
Snow...Just this weekend, here in Dallas, we got some snow and I got out and put them to the test, and for a short 30 minute drive, I never felt uneasy coming from a dead stop, turning, or accelerating (Take it, I never got over 30mph)
OVERALL....I LIKE EM ALOT....I will get another set when these wear out
