Right now: -18F at my house with a windchill of -33F. I’m with @Braxo on this - nothing. Go slow, go easy on the start, leave plenty of room between yourself and the car in front, make sure to have a warm coat, hat and gloves with you in case of an accident. I drive icy roads every day - I really only lock the center diff if I’m driving it off road in unplowed conditions. I wouldn’t drop tire pressure way down - maybe just a little. Increasing the contact patch can’t hurt. You’re in Texas - the most dangerous thing you’ll face in the next couple of days are other drivers being morons. Good luck, stay warm!OK, here in Texas we are expecting some serious ice storms over and through the weekend. Does anyone have any suggestions on the settings while traveling in these conditions? I know the obvious one is to "Just stay home", but I am the only testosterone in the family (besides a neutered dog), so inevitably I am required to run errands, go to the liquor store, pick up toilet paper, etc. All that being said, would you suggest center diff locked in High, or something else? We may have some snow but sleet and freezing rain are the expectation for now. I would drop tire pressure down to 25 maybe if in agreement.
Thanks for your suggestions.
