When the air pressure in a tire is too low, the tire can become soft and squishy. This can cause the car to handle differently than it normally does, making it more difficult to control. For example, the car may feel like it is pulling to one side or the other, or it may be more difficult to turn. In addition, low tire pressure can increase the risk of a tire blowout, which can be very dangerous.
It is important to check the air pressure in your tires regularly and maintain the recommended pressure listed in your vehicle's owner's manual. This will help to ensure that your car handles properly and is safe to drive.
