Thanks for the snow pics, very (very) nice, makes me so jealous of the real snow and mountains you guys get to play in!
Our snow is very wet and heavy, and nowhere near as deep, compared to the light/dry pow you guys get in the US and Canada, ours is probably more like late spring snowfalls in your coastal mountains. We get fresh snow, but nothing I'd call powder, maybe one or two days each year you might get a little pow if there on the day it happens.
And some of the tracks are much poorer quality than the sorts of roads I imagine logging trucks would use, rougher, less defined, ungraded, and steeper for short sections.
No idea yet how my truck will go on it with aired down tyres on our snow, but I do plan to get front/rear diff locks, and internal bead locks to allow the tyres to be aired right down. I also want to have the chains in case I can't get up the short steeper sections just by airing down, as well as a creek crossing up to above the bumpers I will have to get into and out of with snowy banks on each side.
I am leaning towards the 35's, due to the much cheaper cost of the tyres and the mods to make them work, but would still like to be able to go for the 38's.
Wanting to have clearance for the snowchains probably adds an inch or two onto the clearance requirements for whatever tyre size I choose to go with as well.
Stepping up to 35x12.5 from my current 33x12.5 isn't much of a jump in cost, but going to the light truck sizes such as 36x15.5, 37x13.5, 38x15.5, etc. is a massive jump, nearly twice the cost for the tyres in 38x15.5 compared to 33x12.5.
I do not really like the look of the high sidewall balloon style tyres, if I went 38's I would like to go with larger than 16" rims, something like 18" or 20" rims to reduce the sidewall height. Something like these 38's on 20" rims that ujoint has on his truck...
...I think they look much better than really high balloon style sidewalls, but I can not find any custom rims, steel preferrably, in larger sizes than 17".
