The recommended tyre pressure for cars generally falls between 28 and 36 PSI (pounds per square inch). The exact pressure for a specific vehicle can be found in the car's operator manual or on a sticker inside the driver's door post. This recommended value is the optimal cold pressure for safe handling, braking, and overall vehicle performance. It is important not to inflate tires to the maximum pressure stated on the tire sidewall, as that can negatively affect handling and tire wear. Checking and maintaining the recommended tire pressure regularly helps ensure safety, fuel efficiency, and tire longevity.
