what is the ideal tire pressure for a car
One thing that is important for proper driving conditions is proper tire inflation and pressure. The ideal range of pressure in cars is between 193-234 in kPa (kilopascal) or 28 to 34 psi (pounds per square inch). However, in heavier cars, such as minivans, the pressure can be higher, upwards to 303 kPa (44 psi). If a tire is under inflated by 41.4 kPa (6 psi), a loss of handling will be noticed and tire life will decrease. Most notable, fuel economy is reduced by 5%. If over inflated by 41.4 kPa (6 psi), the car will ride harsher since the car is more susceptible to potholes and debris.
