    D3 Snow Performance & 19" MTR's

    Just got back from Mt Skene where I was somewhat disappointed with D3 performance in snow.
    Got stuck twice where others notably same spec TD5 D2 (my son) as my old D2 got thru and snatched me out.
    DSC was off, low range engaged, snow terrain response selected.
    I have rear diff lock fitted.
    First time stuck at 26lb in MTR's.
    second time at 20lb in MTR's.
    Apart from driver error (This was my fourth trip to Mt Skene where previously the only time I got stuck was snatching some one out) what did I do wrong.
    I am now seriously considering bigger tyres!!!
    In addition even though the chassis was rubbing on the snow I was not able to get grounding height selection.

    Have to admit though the drive there was good.

    Any Thoughts???????

    Regards

    Chuck

    wat was the reason for getting stuck,, was its just plane run out of clearance?? i cant say iv never driven in snow, but it is sorta the same as sand, just keep going? and with the rear locker, find it werd for a d3 to get stuck were a stock d2 made it easy

    The D2 is modified notably 265 x 75 x 16 MTR's & 50 mm lift.

    Tried to attach 3 photos.

    First photo shows your D3 half a car width off line. Keeping on line is v important in snow.

    Your setup and technique sounds fine except that selecting snow mode is not the best for deep snow. In that mode the car is set for slippery surfaces, and deep snow requires more power, certainly uphill and even to the depth you had it to as seen in the shots. Normal mode is what I would use (and in fact did that same weekend in snow elsewhere), or maybe mud/ruts. I think that would be the difference. The tyres and diameter would have been fine as were the pressures.

    Snow mode is fine for a thin, loose, slippery covering. Not what you were wading through.

    To answer another poster; sand and snow driving are more different than alike.

    A mate that runs MTRs on his cruiser has changed back to AT or road tyres after he found he was sliding off the road while stationary on snow. His theory is the lack of sipes on the mud terrain tyres prevent them gripping in icy surfaces.
    May not be the vehicle at fault, maybe the tyres.

    MTR Only Way To Go

    Hi,
    I lived at Guthega past Perisher for 4 years and disagree totally, I drove through a lot of very deep snow most days in the winter on BFG Mud Terrains. It will amaze you where they will go. Its like sand; momentum but not too much!!!!!!! (have even had them up the ski slopes).

    MT/R only way to go. Sounds like your technique was wrong.

    Second that. Mud terrains will work really well in the sort of snow you were in. Snow of that nature isn't quite like sand, with snow you're compressing it more whereas with sand it's more about pure flotation. Try shovelling sand vs snow and you can see the difference in texture.

    The LC100 experience was probably more to do with maybe the compound than the tread pattern.

    Hey Chuck,

    I was first time in snow 2 weekends ago in my D3. I didn't like the snow selection with the terrain response, didn't feel like I had control, so reverted back to Mud/Ruts and found it much better.

    Looks like Mt Skene had plenty of snow. Did you have to get a permit to drove there as I heard it's closed at Wren's Flat turnoff?
    Land

    Cheers Neil.

    Neil,
    Yes we did get a permit thru LROCV.
    There was plenty of snow & there should be more this week.

    No one ended up checking permit however on the way thru Mansfield there was a blitz with breathaliser, rego checks, warrant checks, outstanding fines checks & the DSE were there as well.

    In some respects the D3 is harder to drive off road than my old D2.
    I noticed far more sliding down the cambar of the road.
    I have been up there three times in the D2 with much more snow, each time I did not get stuck however that was with 265 x 75 x 16 Mickey Thompson MTZ's aired down to 16lb & a 50 mm lift.

    Perhaps I am not as "brave" with the D3.

    Tyres do make a huge difference if you are doing to try the harder stuff.
    The MTZ's never broke the seal on the rim even when down as low as 12lb.
    On the 19's I have been down to 20lb twice & both times developed an air leak after breaking the bead seal. So naturally now I am averse to going down lower than 20lb.

    One comforting thought though - an RRS with standard tyres was having a much harder time than I did.

    I think I might go to bigger tyres in LT construction that I know I can air down with confidence.

    Does anyone know if 265 x 70 x 17 Goodyear Wrangler MTR's fit in the spare wheel well.

    Regards

    Chuck
