Matt is right. Tire pressure and weight of car are the determining
factors of contact patch size. Wider tires just make it a different
shape; i.e. extended crosswise. But for the purpose of snow braking, it
may very well be that you want the patch extended lengthwise, as it would
with narrow tires.
Matt Pringle had this to say:
