 Get in your car prepared for travel. Don't think it and don't over-flate it. Inflate your tires to tire pressure listed on the vehicle's placard. Don't over-inflate. You'll wear them out quicker. Don't under-inflate. You'll wear them out quicker as well. Tire pressure should be checked when tires are cold and be sure that the car has not been driven for at least three hours. Remember to tightly close those valve caps. Rotate for uniform wear. Every 5,000 miles, guys, you got to rotate your tires.
