First, please do tell more.
Second, I was thinking that the contact patch is dependent on tire stiffness (pressure largely) and normal force (weight and downforce). If you merely fit two tires where there was once one it would seem that the contact patch would be the same. However, if you want to run lower pressures and increase the contact patch and get into a better coefficient of friction due to non-linearities in friction vs. load, you get more heat in the tire due to deformation. If you increase the diameter to make it cooler, then the tire sticks up high and messes up suspension geometry and aerodynamics, but if you do not have to have the rubber in a circle and can split it up into two tires then the aero is better for a given contact patch...
Am I going in circles with this reasoning?
