Yup Stevens Pass. On the way up to the ski area. The stock MT's just would not go straight or move me forward. Was a very tense bit a driving. I drove really slow on the way back down, those things would never stop that jeep in those conditions. Not doing snow trips with those tires again.

As far as the debate to air up or down, it doesn't matter. I know this sounds counter intuitive, but friction force is not relative to surface area. The friction force is simply your weight multiplied by your friction factor. That being said, narrower tires can have added benefits. They sometimes allow the tire to dig deeper and gain an increased friction factor with the road. The only time air pressure really does anything is when rock crawling because it allows the tire to grip around rocks and it changes the spring rate of the tire.

I have stock BFG Rubi tires and I think they're fine in the winter. A lot of people complain that they're bad on ice, but I don't see any real issues. You just have to know how to drive in these conditions.

Exactly my experience, granted there are way more experienced drivers but in this same road to steven pass, oem tires were bad, duratrac 285/70 r17 were perfect. Same jk, same driver, same road one week apart.

Definitely another vote for;

-Good snowflake rated tyres, like Duratracs (I have GoodYear Territory, but same thing, though they are being discontinued so Duratracs next gen).
I have wheeled extensively in the snow on the following stock tyres (SRA-s, Duellers, MT KMs, now Silent Armor) and the only one I'd say is 'good' for everyday snow is the Silent Armour (though I'm going to swap them out for the Territory tyres now that they've been extensively tested in deep snow in Fernie as they don't dig deep like the Territory). To me, the KMs are 'good' for deep off-road snow, the Duellers are OK in Snow but get hard and skatey as you get near 30F/5C, the SR-As are acceptable, but not good and pack up with slush quickly and get just as hard in cold temperatures. But the KMs are particularly bad in ice and crushed snow because of the large tread blocks. Sure they are acceptable at getting around, but there is a night/day difference between them and a pair of snowflake rated tyres on compacted snow/ice, especially for stopping distance and lateral grip.

- Start in 2nd gear on polished ice intersections.

-Air down a bit for slow going in town or slow non-paved roads, stay well inflated for highway treks.

-If you are going to put ballast in the back, make sure it's secured, and be aware that it becomes lateral inertia if you're trying to correct a wayward rear.

Some suggested instead of putting weight in the back, you might as well fill up the tank.

Agreed....
Air down when the depth of the snow exceeds your ground clearance and at that point it is better to float.

Outside of that, used good tires and maintain the proper recommended air pressure.

The name of this thread is winter driving, so I'm assuming we are talking about paved roads.

They are gone as soon as I can get them off of there. Tire choice is key, if it wasn't for 4-high it wouldn't have been able to move up that pass.
I put Nokians on my HR. Drove up to VT in some snow the other day. Much, much improved. They look good too. (265-70-17 on stock rubi rims).

MT tires on slick streets = bad idea.

We had an event in Atlanta 2 years ago that we called Snowmageddon. I know, that term is used a lot these days and our event pales in comparison to others around the world...

But we had a half inch of ice with 4" of snow on top of it. GEMA thought that the storm was going to hit south of here and deployed all of our snow remediation resources south of Macon; there was nothing available here.
When the scope of the event was recognized, every entity in the Atlanta metro area told their employees to go home.
Gridlock of epic proportions.

I closed my lab, sent my students and instructors to their hotels. Most of them walked.
Then I went into the parking lot and did donuts in my Power Wagon for a half hour. Aired-down and then hit the road.
I had no idea about the gridlock...

While trying to get around traffic I encountered so many accidents and stuck vehicles that I literally lost count (stopped counting at 200 wrecks).
Every hill had cars/trucks slid to the side of the road, rolled over, stuck against guardrails. My wife was ahead of me by 5 car-lengths, had aired-down her FIAT, and was moving along fine. She made it up one particularly nasty hill and the vehicles behind her wrecked, blocking the bridge.
I was also blocked from behind by stuck cars/trucks.
So I got out, walked up to the other vehicles, showed them how to air-down.
Every single one of them got un-stuck and I drove home leisurely from there.

Airing-down works quite well on ice. Nothing beats studs and chains though.
I was also carrying a variety of tools, snow melt, cat litter, etc. I was ready...

My wife and we're both stuck on 400 during this. She was in her Acura MDX and me in my Audi A6 (pre-Jeep vehicle). Both AWD on all seasons. We got lucky and found each other on 400 at exit 7. We got through the mess just fine by slightly airing down and going slow....and my wife is a noob but she had me guiding her on the phone. It's amazing how many people I saw in big honking AWD SUv's that were stuck or wrecked. Whole lotta good that AWD does you when you're on summer tires or all season! A little prudence and common sense would have avoided so much pain that day/night.

That's cute. Here that's called a Tuesday. Just teasing, I'm sure on an average summer day there I'd be complaining of the "heat wave" and begging for mercy. Snow is all about proper tires and experience, and it's tough to get that experience unless you live on the ice planet of Hoth like some of us. Mainly don't surprise the vehicle with any sudden inputs (braking, acceleration, steering). If you're in a manual rev matching downshifts keeps things smooth and compression brake as much as you can before stepping on the brake pedal. Leave much more space than normal between you and the car in front, be aware of how cars around you are moving and reacting to the road surface. Reduce speed, keep all your windows clear of snow and ice and have warm clothing with you in case the worst happens. My jeep always has a toque, mits, scarf, snow pants and winter boots in it to complement the warm winter coat I'm wearing. I do also carry recovery gear.

8 hours from Exit 10/Old Milton to Canton.
Only 15 minutes from Arnold Mill to home though. So more than 7.5 hours just to get out of North Fulton.

I have a picture somewhere from 2 days after

That's rough. Took us 13 hrs total to get home from Buckhead. 8 of those hours trying to get off on exit 8. Like you it only took 10 minutes to get home once we were off the highway. So many cars blocking the exits...

I was stuck at the Atlanta airport for that storm. Workers for the airline couldn't get in, and I was desperate to fish in Belize. Luckily we had a huge group of highschool kids on our flight, and they managed to get a crew together for us. All because this didn't happen in Buffalo.

Being a lifer from the Burgh, I would just say:

1. Have the patience to sit behind people who don't know how to drive. They will be driving too slow, and inevitably getting stuck.
2. Be prepared to help pull them out once they've blocked the road 100%
3. Be prepared to drive around idiots "Rambo style" once they've mostly blocked the road / use berms and grass.
4. And don't drive around crappy city areas like Mount Washington in the middle of a snow storm.
5. Don't drive on ice. If you can't get anywhere on foot, you won't by vehicle.
6. Have common sense and a grasp of all-weather driving skills and you'll be fine.

That is all.

It is really based on your individual situation. Where you live, where you are going, how you are getting there, etc.

I don't think a single tire manufacturer advises drivers to air down for winter driving. But is certain situation, airing down could help.

Up north, we don't air down for the winter because that means you would be riding on low tire pressure for multiple months straight....and that would be really bad. You don't want to commute 30 miles on the highway at 60 mph on tires that are aired down.

But a specific short time event is another story.

Just depends...
