Maintaining the correct tire pressure is crucial for both safety and fuel efficiency. Driving with under-inflated tires can reduce gas mileage and cause uneven wear, leading to a shorter lifespan for the tires. On the other hand, over-inflated tires can lead to a rougher ride and less traction on the road. To ensure that your tires are properly inflated, it is recommended to check the tire pressure at least once a month. This can easily be done using a tire pressure gauge, which can be purchased at most auto supply stores. The recommended tire pressure for your vehicle can be found in the owner's manual or on a sticker inside the driver's side door jamb. By regularly monitoring and maintaining your tire pressure, you can improve your vehicle's fuel efficiency, prolong the life of your tires, and ensure a safer driving experience. Remember, proper tire pressure is key to optimal performance on the road.
