Been following this. Newbie question, what is flat plt? ........
The following is from a Goodyear / Titan tire information publication.
A NOTE ON CONTACT AREA
The only contact area that we publish in this handbook is the 敵ross Flat Plate contact area. This is the total area contained within the ellipse of contact resulting from applying rated vertical load to a tire at rated pressure on a smooth hard surface. Previous editions of this book have also published a figure know as 菟enetrated area which was all the area under a tire at the stated penetrated soil depth. It was felt that this figure was misleading because of the many assumptions made in its determination. In soft soil, the ratio between the pressure in the tire and the pressure that the soil can support determines the degree of soil deformation. This is why soil disturbance is minimized by opting for larger tires that can carry the required load at lower inflation pressures.
