* 4WD doesn’t mean that your vehicle has the ability to make a 35 mph curve at 75 mph. I know. I lived in and near ski resorts for decades and watched many a brand new crunched SUV go back toward the cities on the back of an AAA flatbed. 4WD is great for going forward and backwards on snow and ice, but does little in turns except for those experienced enough to know how to correct with the throttle and not the brakes in snow (for older vehicles without traction control). City flatlanders get a new SUV and drive like they see on the commercials without knowledge and skill to know better. Especially adolescent ones, which can and will take out the most experienced snow and ice driver along with them.
* As mentioned before, get some practice if you can. Learn how your rig handles snow and relax and don’t white knuckle it. Quick and erratic steering inputs often lead to negative results.
* In most states, there are special speed limits imposed when there is snow on the road. They are there for a reason. Unfortunately, many flatlanders tailgate those who are sticking to the rules, with negative results mentioned above.
* It sounds as if where you are going will receive little snow or if it does will be quickly plowed. Actually, all terrain tires do best in deeper snow, as unpacked snow actually enhances traction. Plowed roads lead to ice, which is more likely to lead to driving issues. If it’s sunny, ice will have a melting ice water coating, making things worse.
* As said, put it in 4WD HI as soon as you encounter ice. It doesn’t hurt to have your vehicle in 4WD HI for short stretches of dry highway if the road doesn’t have sharp turns (I know, I’ve more than once accidentally knocked my old 2002 Tacoma, with an electronic 4WD activation button on the side of the transfer case shift lever, into 4-HI while vacuuming and went on my merry way for tens and dozens of miles at highway speeds before making a 90º turn onto another street and then encountered drivetrain wind up). I often leave my old trucks and current 4Runner in 4-HI on stretches of highway and interstate with stretches of alternating dry/snow/ice/wet conditions without issue.
* And if you feel you are getting in over your head, there is no dishonor in turning around and getting out of the snow and ice.
