[QUOTE="Fred W, post: 1230099, member: 3828"] From what I recall, the contact patch size (total area) is not affected much, if at all, by the profile of the tire. The shape of the patch will certainly vary, but the size of the patch is entirely dependent on the amount that the rounded tire deflects, which is more related to the weight of the machine and the pressure in the tire. When a lower profile allows a wider patch, the weight being supported by a wider area of tire will deflect the tire less producing a shorter patch. And vice versa. Now the shape of the tire might bias the various performance characteristics of the tire differently; for instance, the lateral adhesion (for cornering) vs. longitudinal traction for acceleration and braking. Just something else to consider. [/QUOTE]
