I have been running the at3 35x11.5 all year in all the weather and terrain I can find. Love them. Great in snow and mud, forest roads, rocks. They've done it all. I went with them so there would be less poke and less rocks flung into my hinges. I usually run them 36psi on road, 15-20psi offroad.
skinny tires are better at almost everything, fat tires are better in mud and sand. This is not fact. It's purely opinion, but to my knowledge it's the general consensus.
A toyota guy released a very informative video coming to the same conclusions that most of us around here watched about 6 months ago. There were some potential errors in isolating variables though, for example he used the same width wheels for both tires, when testing them both with their ideal width wheel would have been a touch better. But this is the internet, and a guy made a video agreeing with my previously held beliefs so i gotta believe it, right?
For bias identification: i run 315s (12.4) because i was one of the lucky kenda blowout beneficiaries, but if price weren't a factor i'd probably be running 11.5s
Narrow tires are better in most situations, other than deep off-road snow, water on top of mud and sand.
Pounds per square inch.
He also mentions not having 12.5” wide on his daily, but… Wisconsin.
Better on road in rain.
Narrow tracs better on road.
Just a few snippets from:
I runs a 10” wide all terrain on base Mojave wheels in the winter and they are phenomenal. Michigan.
I myself will never ever again want anything wider than my summer 10.5” wide R/Ts and I could do without them and stick to my winter 10” wide A/Ts year round.
Like my dad tried to tell me at 16 (I’m 51), “wide is just more slippery surface you’re riding on.”
