Although toe out/in plays a role in this road behaviour, it is fairly
limited. In most of the cars I have had, I preferred a zero to a slight
toe out with negative camber and zero to slight toe in with positive
camber. Castor and camber however are more important but usually limited
in adjusting if adjustable at all. If possible adjust to slight negative
camber. Make sure left and right readings are the same.
Also the alignment and tightness of the rear axle suspension should not
be overlooked and last but certainly not least even tire pressures and
tire condition have a major influence.
So check your tires and their pressures, tighten up all the nuts and
bolts, check all bushes and joints and have the complete 4-wheel
alignment checked if the problem still persists.

<div>Michael:Â 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. </div>
<div>Â </div>
<div>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.  </div>
<div>Â </div>
<div>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.</div>
