Tire Tread And Tire Inflation

For the most part, it won't have any effect on it. The reason for this is steel belts which run the circumference of a radial tire (radial tires are found on almost all passenger vehicles ... bias ply may be used for specialized vehicles/needs, but really aren't too prevalent in day to day life). The steel belts help the tire roll, but they also provide a fairly solid surface as well, which means there isn't going to be much flex in the tread area.
