I'm really curious about how the Toyos do in snow/rain - their tread siping is almost none existent. Definitely look like an excellent offroad tire though.
Like a tank tread. Even now with 20k miles on them, showing moderately heavy wear wear, they still do the job. The fronts have been in need of replacement since last August, I've just been too lazy to have the new ones mounted. Ice. Snow. Mud. Sand. Roads ranging from tire tracks through the Sandhills to the pavement on the interstate in all weather conditions. I have a set of tire chains that I have never even opened the package.
I run mine at 30PSI on pavement and hardpack off road, 22 when I am crawling through the rough stuff Took some experimentation but chalk test showed me the proper inflation for pavement. (rated at 33). Off road pressure depends on the terrain. Softer for solid rock, slightly harder for sand and mud. I am also careful with my "empty" loading. I keep a wide range of tools and science equipment in Bert at all times with the weight stowed to offset my weight- in other words, I keep it balanced.
I think a lot of tire traction complaints are a result of improper inflation, something I learned about here on the forums. (Like most folks, I was taught you always run at the pressure on the sidewall. I also joined the local Jeep club for their annual Newbies run last year, where I got excellent driving instruction from a professional trainer. I think a lot more complaints relate to poor driving style- it's a Jeep, not a racecar.
We joke at the Fortress of Squalitude that "Bert just drives over stuff."
