I have been running these Geolandar ATS for 2 months now and I live in a tropical country so my "SNOW" rating isn't relevant.
Noise - I came from a Dueler HT and I cannot tell the difference!!! Finally an AT that is as quiet as a HT!! I am so satisfied!
Grip - Great in both Wet and Dry! It grabs on and gives me so much more confidence on road than my Dueler HT. Off road is good and does as expected. However, dont expect this to be your ultimate offroader option. This is really perfect for the 90% on road with occasional offroading type of driver.
These are stiffer than my HT but that is also expected. I suggest going up a sidewall height when switching to these from HT. Switching from another AT should be the same.
