Why tire air pressure is important:
- Underinflation increases treadwear on the outer edges, and generates excessive heat, which can age tires faster
- Fuel economy is reduced as rolling resistance increases — soft tires make your vehicle work harder
- Too much air pressure causes the center tread to carry most of the car's weight, leading to faster deterioration and uneven wear
To find the proper air pressure for your tires, look in your vehicle's owner's manual, on the sticker on the driver's side doorjamb, or in the glove box.
