Severe fishtailing on snowy roads - tires are fine Sign In

Ive got a 1990 Chevy Malibu. 3.1 L

2 front tires are 1 year old. 2 back tires are still in good shape.

This winter ive been fishtailing severely, even when the roads aren't all that bad. And its not my brakes. It does it all the time. It's very scary. I hardly go over 30 mph and it still fishtails. Even goin 20 mph right down a straight road in town.

What the heck is going on?

The first thing I would look for is a broken shock or sway bar. Make sure the brakes are not dragging or grabbing too much.

To add: Tires are not created equal. Take a good look. If fronts are better put them on the back as a test if all else checks out on HT's list. I own lousy real snow tires with 3/4 tread on working 4X4 that just don't have plain good traction!

Tires for "all season" are rated for traction with a letter designation but that's not 100% truth IMO. Also know that 1/2 worn tires don't have half the traction of new - it's more like 1/4 of new - big difference.

If this can fishtail on dry road it more suggests a mechanical issue,

One more thing to add to the list would be to have the alignment checked.
Have you recently hit a curb hard, pot hole or backed up & hit a parking block?

The rear tracking could be off off & what happens is the rear will start to go to one side or the other and then frt will pull it back into line. It feels like a kind of jerking in the rear, I could only imagine what it would do on a snowy road.....

Well, last winter I lost control and hit a snow bank pretty hard with my front end. That's about it though.

I was told if it was the sway bar or something of that nature, it would be fishtailing all the time, regardless of the weather. It seems fine on dry roads.
