heent gives good advice.
A big part of winter driving is to be smoooooth. Real smooth with the brakes, gas, and steering.
Don't do anything real suddenly, if you can help it, or you will be sliding.
In 4wd the front end will want to push around corners in the snow, i.e. go straighter than what you have turned the wheel, and the more gas you give it the worse that will be. I try to coast around sharp corners or give it as little gas as possible and in my '05 I'd often just switch the 4wd off to turn a corner, then switch it back on when I got straight. Not an option in my '08.
I never put weight in the back of my Tracs (I'm on my second one) like I did my Rangers, I don't think it needs it.
I'm with
Todd Z on tires. I had Bridgestone REVOs on my old '05 also and it would chew through anything mother nature could throw at me until such point as it was snowing so hard that I couldn't see where I was going. Which has happened. Curiously my '08 goes and turns very well in snow with the stock Goodyears but braking in snow is horrible and downright dangerous. Be getting Bridgestone A/T's or REVOs this summer.
Dedicated snow tires do make a difference if you need to get serious, but I've never bothered to get them on my trucks. My wife's Taurus has Bridgestone Blizzak snow tires and it goes every bit as good in snow as my truck and better on ice and in braking.
Ice basically sucks and there isn't much you can do. Winter here is more wet than anything, past two weeks excepted
and I think studs do more harm than good. Plus once they wear down they're useless anyway. Snow tires have real soft rubber to grip on ice without studs plus it doesn't get as hard when cold. The tread on my wife's Blizzaks feels like a pencil eraser and it's literally tacky.
