This recommended tire pressure is specified by the vehicle manufacturer to provide the best balance of handling, comfort, and fuel efficiency for the vehicle. Tires that are inflated to the proper pressure will allow the vehicle to handle properly and provide a comfortable ride. Under-inflated tires can cause poor fuel efficiency, uneven tire wear, and can eventually lead to a tire failure. Over-inflated tires can make the ride harsh and uncomfortable, and can also lead to premature tire wear.
It is important to check the tire pressure regularly and adjust it as needed to ensure that it is at the proper level. The tire pressure should be checked when the tires are cold, which means they have not been driven for at least three hours. The tire pressure can be checked using a tire pressure gauge.
If the tire pressure is not at the proper level, it can be adjusted using a tire inflator or deflator. When adjusting the tire pressure, it is important to only add or remove small amounts of air at a time. Over-inflating or under-inflating the tires can damage them.
If you have any questions about the recommended tire pressure for your vehicle, you can consult the owner's manual or contact a tire dealer or automotive service center.
