SUMMARY
The formula for calculating gauge pressure in tires is derived from the relationship between force, area, and pressure. In this case, the total weight of the car, 1142 kg, is distributed equally across four tires, each with a contact area of 96.5 cm². The pressure can be calculated using the formula: Pressure = Force / Area, where Force is the weight of the car divided by the number of tires. Therefore, the required gauge pressure for each tire is determined by converting the weight into force (using gravity) and dividing it by the contact area.
