This spreadsheets calculates the tyre contact pressure and contact area for a special dual or super size tyre arrangement.
The spreadsheet takes user input values for wheel type and wheel load, then calculates the tyre contact pressure and contact area. The contact area is calculated as either a circular or rectangular area.
The spreadsheet also a includes unique tool allowing the user to see the effects of different wheel loads without re-entering any of the input data. This makes it easy for the user to calculate the contact pressure for different wheel loads and pavement thicknesses.
