Michael: I recently switched from Vredesteins to Michelin XAS's. I am =
experiencing the same situation. The only thing I can do is guess =
because I don't know the tire construction and science. The XAS has a =
wider sidewall, 90 aspect ratio I think, about 4 inches wide, versus the =
Vredestein 70 aspect ratio, about 3 1/2 inches wide. Is this extra =
width allowing for extra movement of the tire from side to side? I =
don't know. =20
As I say, I am only guessing but I have experienced the sensation =
before. When I was stationed in France, I had a Renault Dauphine.The =
original tires were bias ply tires. When you turned the steering wheel, =
the car turned instantly. The old tires were replaced with XASs. Then, =
when I turned the steering wheel, there was hesitation. It was as if =
the tires were tracking into the turn but the body of the car didn't and =
had to catch up. With nothing else changed, the answer, to me, was a =
more flexible tire. =20
One, or more, of our experts may provide the answer as to whether or not =
the wider XAS sidewalls are allowing more tire/body motion.
One other note, the situation seems to be aggrivated by grooved =
highways.
