Did you know that the tire pressure number written on your tires might not be the right pressure for your car? When filling your tires, it is always best to follow the vehicle manufacturer's recommendations. This information is in the owner's manual.
Tire pressure is important because it affects how much of the tire comes into contact with the road. Overfilled tires have less surface area touching the road, which reduces traction and handling. Tires with too little air pressure produce a lot of drag, and they can be difficult to control on poor road surfaces.
