As I said, my previous Jeeps were all capable in snow. My last was an '02 GC Overland with 235/65-17 on General Altimax winter tires (traded for the WK2).

I tried it (WK2) on snow covered quiet roads and country roads recently and it didn't do too bad. I even adjusted the tire pressures down to 33 psi (from 36 psi as recommended for the 20" Fortera) and that improved things. I felt that I had this figured out and solved until we had another bout of bad weather on the weekend.

Nope. On the WK2, the front uses a brake lock differential, only the rear has a ELSD. There's been debate as to how much the off road performance has been impacted, but it's looking like in actual real world terms, the front ELSD isn't missed.

I've had zero snow issues in my QTII vehicle. I've been out in the nasty stuff several times and never had any real issues with the stock Forteras. I did feel a little squirm a couple times when I got on the power while turning, but certainly nothing that made it step out. I have been thinking about some dedicated winter rims and tires for this thing, but I'm still not sure if I'll pick up $1300-1500 worth of traction (which is what they'd end up running).

Thanks for the clarification. I knew the rear for sure but I thought I read that the front had something similar in order for any one wheel to get 100 % power.

I suspect it's tire size that may make a difference in snow. I should have gone with narrower tires but that meant going one more step down to 17"...245/70-17. The 17" winter packages (Tire Rack) had more choices of tires too.

That's why I'm trying to figure out if the 17" rims will fit my GC. In the 18" size (265/60R-18), there's only three or so choices- Bridgestone Blizzaks, Pirelli Scorpion Ice/Snow, and Yokohama Geolandar I/T. Of those, the only ones that seem to be readily available now are the Blizzaks, and I'm not sure they'd be the best for me (early Blizzaks seemed to wear really fast when they weren't on snow; around here, snow really only sits on the roads for a day or so after a weather event). At the 17" range, there's a dozen or so choices, some well under the price of the Blizzaks. But then, I would not be able to use the sweet looking black Jeep rims (which are themselves not cheap).

Re: Unsure about snow performance

Ever since I deflated the tires to a normal setting versus the factories way high pressure, I've had tons more confidence with the stock 18s... I went up and down a Hell of a steep inplowed mountain road with about 6" of snow on it without any problems

Re: Unsure about snow performance

Just to clarify, the QDII has the ELSD while the QTII does not...or did Jeep change the layout? My QTII does not have the ELSD although relatedly the QDII and QTII share the same 2-speed transfer case. I haven't had the thrill of the rear kicking out yet and I've tried (stock 20" Forteras). RedG8R I'm surprised the Blizzaks are not preventing the happy-tail you are experiencing. Do you have QDriveII with the ELSD or QTrakII? Have you eliminated the transfer case as the culprit (not actually engaging the front wheels)?.

With the WK2 I was testing the abilities in a empty lot so I could get use to it's feel and the tail end would come around on me almost every time. Normal and snow modes.

I thought maybe that the Hemi just had too much power but the more I test it the more it seems like something is wrong. This morning I put it into 4 low to see if I could feel the front end grab on dry asphalt and even around a corner i did not feel the binding like I think it should have.

Anyone else think this is very wrong ? I'm getting to the point of changing clothes when I get home tonight and making sure the factory didn't forget to install the front drive shaft!
mine is nothing like that. i put mine 4low to make sure it worked and it pop my head off the headrest.

May I ask what pressures are you using?

Re: Unsure about snow performance

[QUOTE=wjs81866;317543]What tires do you have? The 18" latitudes are poor on ice and snow. Changed mine to Michelin LTX M/S 2's and it made a big difference. The system as it works is very different then my 98 5.9 LImited and 96 Limited. I have been driving around a lot more in the snow and I have become more accustomed to the way it behaves on ice and snow. The old school driving skill is at conflict with the system wanting to take over and go about the braking to prevent oversteer etc. The tires made a difference though. My wifes Limited has the Goodyear 20" and they seem to handle much better. None of these tires are over the top great on snow ice but I find the LTX M/S 2's to be the best all around tire.[/QUOTE]

You are correct I was in the mountains in PA this past December hunting with my Dad and he had the Michelin LTX MS2s on his '04 Dakota. We were going places in deep snow and ice in other places where all others were running tire chains just to make it up hills and even to stay on the narrow mountain passes. I can't speak for how well they are on road but I just couldn't believe it…the traction that truck had. I thought we were going to get stuck because of how deep the snow was (dragging bottom and pushing snow at times) but the tires never slipped a wheel they just went even on ice it was remarkable. His previous tires were Goodyear's and we couldn't go anywhere without putting on tire chains. It was like a different truck. They're an awesome tire.

Re: Unsure about snow performance

It took approximately 1,000 miles for the WK2 and I to get comfortable with one another in the snow, etc. Blizzaks and all. Now I'm quite comfortable driving in the flakes.

Re: Unsure about snow performance

Did any of you guys get the ESC update from 1/8/2011? Or have a Jeep built in January?

I wonder how this would impact everyone's snow performance.
