Possibly, but probably not anywhere near as much as you might think (if much at all), especially if ALL tires are properly inflated. If properly inflated, the weight of the car is only going to displace or spread the tread out on the road surface to the degree that the weight of the vehicle is supported. Now, different rubber compounds, different radial/bias, etc. tire-construction types and tread configurations can make a difference in road adhesion qualities, but amazingly, tire contact patch area doesn't change that much with 'LARGER' tires. Simplistic example below! DD
