According to the U.S. Department of Energy, underinflated tires waste up to 3.3% of your fuel costs
You are less likely to be stranded on the side of the road by keeping your tires properly inflated. According to AAA, 13% (4 million of the 29 million) of their calls annually are tire related
Properly inflated tires wear more evenly and reduce pressure on the sidewalls extending the life of your tires and tread. According to a Goodyear Tire Corporation study: For every 1 PSI drop in inflation pressure, tread wear increases by 1.78%. If a tire remains underinflated by 2 PSI over its lifetime, the tread wear would increase by 1.78% or about 1600 miles (45,000*.0356). If a tire is underinflated on average by 6 PSI or 10.7% , tire life will decrease by 4,800 miles.
