How to extend the life of your car tires
Check your tire pressure weekly.
Unscrew the cap on your tire's air intake and hold a tire pressure gauge against it, allowing air to flow out of the tire and into the gauge. All tires on your vehicle should be evenly inflated.
If you don't know the proper tire pressure for your vehicle, consult with the vehicle owner's manual. Additionally, all tires imprint recommended tire pressure directly onto the tire.
