Tire Safety Guide Manual
To find the proper air pressure for your tires, look in the vehicle owner s manual, on the driver s side door jamb or in the glove box. And if you buy new tires, be sure to learn the correct pressure from your dealer. Check your pressure at least once a month, and use a good quality air gauge. Or, stop by your local Goodyear dealer and have your air pressure checked and corrected for free. Maintaining proper air pressure is the single most important thing drivers can do for their tires. In the space of just one month, a tire can lose 10 pounds of air pressure.
It is important to check your air pressure regularly, to make sure your tires are neither under- nor over-inflated. Under-inflation is the worst enemy your tire can have. It causes increased treadwear on the outside edges (or shoulders) of the tire. It also generates excessive heat, which reduces tire durability. Finally, it reduces your fuel economy by increasing rolling resistance - soft tires make your vehicle work harder. Over-inflation is also detrimental to the tire. Too much air pressure causes the center of the tread to bear the majority of the car s weight, which leads to faster deterioration and uneven wear. Any kind of uneven wear will shorten the lifespan of your tires. over-inflated wear zone under-inflated wear zone
