What's better on deep snow (snow offroading), all-terrain tires or mud tires?
And
What's better on deep snow (snow offroading), narrow but high tires or wide but low tires? (talking about 2" or 3" inches difference)

 

Deep Snow would be a wide mud tire. only if its like snow wheeling you're talking about.

on the road snow you want a skinny A/T

 

my wide all terrains do fine on road and off road in deep snow

its when i hit ice they hate it =P but thats all tires worse enemy's right ?

 

Thanks for the reply.
Yes I'm talking about snow wheeling, and could you explain why (mud tires and wide but marrow AT on-road)?

 

It's all about weight, footprint pressure, sipes, lugs, flotation etc.
Lets say you want a tire that's good off road in deep snow, flotation tire - wide with big lugs is probably best because they have a wide enough footprint to ride ON the snow & shovel through it.
A skinny tire will cut through the snow & possibly dig you deeper BUT on the road it will offer better grip because the weight of the vehicle is in a narrower area giving better grip - to a point.
In my view a good tire for off road, snow, mud etc will have enough siping (the narrow slots in the tread which = more biting edges) to give you good on road traction & yet be wide enough to "float" over the snow at low RPM while moving you forward.
Look at the Antarctic expedition vehicles, they all have wide tires with a lot of siping for flotation to ride ON the snow & have grip on the ice etc.
Keep in mind that a lot of it has to do with the driver & their skills in & out of 4wd.
You're not going mud bogging where you mash the gas & take off to skim over the mud. In the snow a better choice may be slow & easy as to not dig yourself in.
BFG KM2's are an all around great tire in my view, but there are many more out there to suit your budget & likes.

 

I like the narrow mud tire in the snow better. Instead of floating on top, dig down through the snow to where the traction is.

Of course this won't work if the snow is really deep, then it'd be better to try and float on top.

 

i run a 39.5x13.5 inch tire for really deep snow and a 32x11.5 for on road snow driving. both work great. the 39 is a irok and the 32 is a bfg a/t.
