Very Good,glad to help.Below,it's put in perspective.
Facts:
1) Under Inflated Tires decrease a vehicles MPG by 3.3%
with over 250 Million Non-Commercial vehicles citizens could save 5.0 billion gallons of fuel.That's roughly over 650,000 fuel transport trucks parked in line reaching from Seattle, WA to Key West,Florida and back.
2) 40,000-70,000 accidents occur each year die to under inflated tires.Over 30,000 of them results in injury.An estimated 660 deaths could have been prevented.That's the equivalent to the number of passengers and crew aboard 3-4 Boeing 727's crashing each year.
3) Under inflated tires increases green house gas emissions by 250 Lbs. per. automobile each year.Americans contribute 57.5 Billion extra pounds of CO2 per. year due to under inflated tires.That's equivalent to the weight of over 520,000 Elephants.
Mind boggling isn't it?
