Unsure about snow performance

Ok so after a few weeks of driving on snowy/icy roads I'm not really all that happy with the performance on snow and ice. Honestly it feels more like a rear wheel drive vehical than not.

With my old TJ and even my 06 Grand (basic laredo 4x4) when I'd get on the gas in a snowy corner the vehical would spin but the front wheels would pull it around the corner and keep from getting too loose. 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!

Re: Unsure about snow performance

Not a ton of snow input just yet from members, but I specifically like how getting on the throttle post rear slide can pull the rig straight.

Are you running stock rubber? Would be interested in what you find out.

Re: Unsure about snow performance

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.

Re: Unsure about snow performance

Blackwolf, did your '06 GC have ESP? wjs is on to something with having to learn to drive a modern, computer-controlled car differently in the snow. I've found the WK2 to be very sure-footed in the snow, even with the stock rubber. My old '06 KJ (which had ESP) was like a mountain goat, especially with A/T rubber on it. I'm finding the WK2 to be just as good in the snow even with the crap tires. Having full-time 4wd (versus part-time in the KJ) is nice, too, because I don't have to turn it off & on all day as I hit dry patches.

Re: Unsure about snow performance

No issues for me in the snow. We had another 10cm last night and while other vehicles were sliding around, the WK2 felt very secure. I went through a 2.5 foot bank in front of my house like there was nothing there. Running Hakkas for tires.

Feels as good as my 2000 model with QD1. That Jeep had so much traction it was almost a fault. It could drag it's belly when it did not have the clearance on obstacles.

Re: Unsure about snow performance

I can't remember what set of rubber came with mine, it's the stock 18in tire but I believe there were two options and I can't remember whaich I have. I'll look tonight.

My 06 was a QD1 with ESP. So far it handeled better in the snow than this one does.

The thing that really has me worries in the fact that I felt no driveline bind around a dry corner with 4Low engajed this morning. I'm going to sniff around underneath the truck this evening maybe do some more controlled tests.

Maybe I just have to get use to it but it just feels a lot less in control than I feel it should.

Re: Unsure about snow performance

No problem for me with the stock Latitudes so far, but then again I only had a couple inches to play in so far.... forward traction was impressive, abs modulation in snow mode was spot on, and I could do 4 wheel drifts with ease

in any event its much more stable then a rwd Mazda RX8 with snow tires -shrug-

Re: Unsure about snow performance

I've been pleasantly surprised so far. The roads here have been more icy than snow, but in the snowy patches and unplowed roads, the performance has been great (I have the 20s).

I have noticed that the 4WD engagement has been completely seamless (QTII). I noticed slight differences in snow mode vs. auto mode, but it's certainly nothing like an old-school 4WD system (and definitely not like the 4WD in the 07 Wrangler I turned on). No crow hop around corners, which I certainly don't miss.

The combination of ESC, all-speed traction control, and the 4WD system can take some getting used to if you haven't experienced the systems working together before. I noticed that depending on the conditions, the ESC and traction control seem to kick in, and not the 4WD system itself. It really depends which wheels have traction and which don't.

But overall, the system has worked well so far.

Re: Unsure about snow performance

I had my first chance to try mine out with a snow storm we had a couple days ago. I think the snow traction was great on take off it would bite good and I didn't have any problems or complaints. The next day we had a lot of icy roads all day and I had to do a lot of driving probably 70 miles on off and on icy roads. There was one time slowing down on pure ice it seems like the rear wanted to kick out but didn't. Then later that night driving home I approached and areas that was all ice again and as I started to slow this thing went almost sideways. Not really sure why just started to slow from about 35 and the rear started to come around and then I was able to get it staightened out and continue. I was lucky no cars were coming from the other direction. I have had 5 Grand Cherokees and never had this happen. Normally when you slow on ice I hear the ABS and the vehicle stays straight and this one seems to do the same in almost all cases except those two incidents.

Towed a 3300 lb trailer about 15 miles the other day in 3 inches of fresh snow. I have the 18's and had no problem. But definitely glad I had the Hemi power for that. I do like the ability to manually control the 4 wheel drive like in my 02 grand but this jeep seems to handle better than my 06 commander in the snow probably because of the extra weight.

Re: Unsure about snow performance

I think it is the ESP you are not use to. You steer as if you would on a normal dry road pointing the car in the direction you want to go, not by thinking of the conditions and preemptive correcting for the motions. It is very hard to get use to in the snow and it varies by vehicle.

Re: Unsure about snow performance

I have the 18" latitudes. We have had lots of snow and a rain / ice storm that has coated our roads creating the worst situation (ish).

I am not very impressed with the traction from these tires. I get by....but I don't think I have the traction my old Acadia provided. I don't want to get a second set of winter tires.....as I thought that's what Jeep would provide with ALL SEASON tires on an OFF ROAD ADVENTURE rated vehicle with traction control, yadda yadda. What was I thinking?
