Greetings All,
Actually, the more narrow tire will perform better in snow that the fat tire
(why drive your MG in snow?) It will "cut" into the snow where the fatter
tire will tend to "ride" on top of the snow.
Many years ago there was an excellent article on this topic. The wider tire
with the lower aspect ratio actually has the same size footprint as the
narrow tire with a taller aspect ratio. Something about the Law of Archemedes
and equilibrium of the forces involved. The key point is the shape of the
footprint. The wider tire will have a wider footprint and that will be able
to generate a larger slip angle before the limit of adhesion is reached.
Therefore, cornering forces will be greater than otherwise.
Should I put on my flame suit now?

Oh, yeah, that's right. It is best to decrease your footprint for better
tractions in all situations.
