I love Toyo's, and up until about 6 years ago, only ran the AT's. However, something changed with the AT3 that made the tread less able to clear mud. Whenever I was in a muddy place, I was having to spin the tires aggressively to clean them off. While I never got stuck, I was being rough on my roads. I switched to the R/T's and then to the M/T's because of this. Now I run M/T's on everything except the wife's vehicle.
