According to the National Highway Transportation Safety Administration * proper tire maintenance will ensure:
“Protection against avoidable breakdowns and crashes. Improved vehicle handling. Better fuel economy. Increased tire life. These are just a few of the reasons to take five minutes every month to check your tires.”
What to check
As the only contact point between your vehicle and the ground, tires have an important job. To make sure they perform at the highest level there are several safety items that should be checked regularly.
Tires naturally lose air pressure and should be checked at least once a month (including the spare) to prevent dangerous under-inflation. Your vehicle may be equipped with a Tire Pressure Monitoring System(TPMS) which identifies an under-inflated tire. Whether or not your vehicle is equipped with TPMS, tire pressure should be checked regularly.
Accurate Pressure Reading
The tire inflation number is your vehicle’s recommended tire pressure and vehicle load limit. Tire inflation pressure can be found in several places:
- Your owner’s manual
- Printed on a permanent tire placard attached to the vehicle door edge, on a doorpost, glove-box door or inside the trunk lid.
Use your vehicle’s PSI number to accurately inflate your tires.
Note: To obtain an accurate tire pressure reading, measure tire pressure when the tires are cold and the car has been unused for at least three hours.
Rotate your tires every 7,500 miles or during your regularly scheduled oil change. (Some Mitsubishi vehicles require tire rotation at 3,750 miles. Make certain to consult your maintenance guide for the specific mileage interval.) This process will ensure your tires are wearing evenly and your brake components can be checked at the same time for wear and safety.
Balancing and Alignment
Tires can vibrate or ride harshly if they are not properly balanced. This condition can be corrected through rebalancing. Also, making sure your vehicle is properly aligned will make sure your tires are tracking correctly, and prevent excessive wear.
Advantages of properly maintained tires
Original Equipment (OE) tires are highly recommended for your vehicle. OE tires are tested during vehicle development and are chosen for their ability to provide a smooth ride, increased performance, better handling and improved fuel economy by up to percent.** By maintaining your tires you’ll decrease the likelihood of a blowout and increase the safety of your vehicle, especially in bad weather. It’s easy to overlook the importance of the tires, but a little preventative maintenance can help your vehicle drive better, safer and more efficiently.
You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
When it comes time to replace tires, ensure the same tire type and size as originally installed on the vehicle are used. To ensure the proper operation of ABS, speedometer, and transmission, always match tire sizes at all four wheels.
