I have a 1994 Full-Size (K1500?) Blazer. I live in Colorado and this is the first winter that I have owned it. It seems a little squirrelly on wet or snowy roads. Is this normal? The 4x4 seems to work fine and I can definitely tell a difference when engaged.

 

What tires do you have and what kind of shape are they in? You can have all the 4wd in the world but it's still going to suck in the snow if you don't have good tires.

 

Any rwd vehicle will feel squirrely in the snow if you tend to be going just a little bit faster than the conditions allow. Shifting in to 4wd will get rid of the feeling and keep the rear end planted better, until you exceed the safe speed again. Fwd vehicles do really well in the snow, or rather packed down snow, but will turn squirrely with the speed again.

Using tires made for snow (NOT all season tires!) is probably the best thing you can change to make your vehicle better in the snow, other than chains. Living in Colorado, you really should have a second set of tires for the winter, regardless of what kind of vehicle you own. If you live in the mountains, you should also carry chains or cables.

Where I live, we have snow that stays on the ground from November through April. These are the months I have the winter tires on. We tend to get our first snow in late Sept/early Oct, but that snow melts off pretty quickly. Our last snow is normally late May, but the snow in April and May melts off quickly, too.
