Correct Tire Inflation

Correct Tire Inflation is critical for the following reasons:

1. Fuel savings: It has been reported that for every 10% of under-inflation on each tire on a vehicle, a 1% reduction in fuel economy will occur. In the United States alone, the Department of Transportation estimates that under inflated tires waste 2 billion US gallons (7,600,000 m3) of fuel each year.

2. Extended tire life: Under inflated tires are the #1 cause of tire failure and contribute to tire disintegration, heat buildup, ply separation and sidewall/casing breakdowns. A difference of 10 lbs. in pressure on a set of truck duals literally drags the lower pressured tire 13 feet per mile resulting in reduced tread life. Under inflation can significantly reduce the number of casings that can re-treaded. Over inflation  wears excessively in the center of the tread

3. Safety: Under-inflated tires lead to tread separation and tire failure, resulting in 40,000 accidents, 33,000 injuries and over 650 deaths per year. Properly inflated add greater stability, handling and braking efficiencies. Not all tire failures are caused by under-inflation. Structural damages caused, for example, by hitting sharp curbs or potholes, can also lead to sudden tire failures, even a certain time after the damaging incident.

4 .Environmental Efficiency: Under-inflated tires, as estimated by the Department of Transportation, release over 57.5 billion pounds of unnecessary carbon-monoxide pollutants into the atmosphere each year in the United States alone.

Cold temperatures affect the air pressure in your tires. There is a loss of one pound for each ten degrees of temperature drop.

Check pressure when tires are cold having been sitting for a few hours. Low profile tires do not necessary look underinflated so check your tire regularly.

Under normal loads, you should inflate tires according to the vehicle manufacturer’s recommendations, NOT the maximum pressure listed on the sidewall.
