I never really had this problem in a car or truck or at least I never notice it. But on the other hand when I drove a truck with new drive tires, oh yeah definately squirrely. Matter fact I jumped in the mack a few months ago with an empty side dump trailer. Did notice it at first until I was tooling down the road about 60mph and come around the curve and I about crapped my pants. I was like oooohhh ****, its coming around. It was like you were driving on ice. Once I got it loaded it wasnt as bad, but still wasnt very fun to drive. Until they got broke in, absolutely no fun to drive unless you like excitement.
